A major scandal rocked the auto industry two years ago when it was discovered that the car company Volkswagen had been systematically cheating on diesel emissions tests. That scandal might soon turn into a big boon for electric cars in the Central Valley.
The company agreed to a massive settlement worth more than $1 billion. Over the next ten years, $800 million is supposed to be spent in California to beef up electric car infrastructure and access. Of that, 35%, or about $280 million, is earmarked for low income and high pollution areas like Fresno, Bakersfield and much of the rest of the San Joaquin Valley.
Joel Espino, with the environmental advocacy group The Greenlining Institute, says the focus is on these areas because they have suffered the most due to VW’s deceit.
“Those emissions, those extra emission, that were put into the air, didn’t affect everyone equally. A lot of the communities who live near busy roads and freeways, low-income communities of color, were harmed the most as a result,” Espino says.
So now a plan is in motion to build up the support network needed to make electric cars viable in low-income areas and across the broad rural plains of the valley.
Dean Florez is with the California Air Resources Control Board, which helped craft the settlement.
He says previously the Central Valley was not appealing for companies to set up charging stations on their own. This led to a chicken and egg scenario, where there aren’t enough places to charge so people are turned off by EVs but there aren’t enough EVs for companies to install charging stations.
“I mean it is kind of like asking someone to buy an IPhone, having it fully charged. And then leaving the store and being told you can only charge it at the local post office which might be 30 or 40 miles away.” Florez says.
Florez sees this settlement as just the boost electric vehicles need. And it’s coming at a time when electric vehicles seem to be finding their niche. This year, EVs are expected to represent about 3% of new car sales state wide. That would be an all-time high.
According to the California DMV, there are almost 168,000 all electric vehicles registered in the state.
“We really want folks to feel like even though they can’t charge at home, they still will have the ability to charge out in the world. You know, you can’t put gas in your car at you home. Most people don’t have a gas station at their house. So it%u2019s really it’s no different than that”-Jamie Hold
At this point, it is unclear where the stations will actually go. However, Florez says they have an agreement with Volkswagen to check in every month and make chargers are being spread out to the areas that most need them, not just the areas where they will be most used.
“Unless we have more density in terms of infrastructure, getting the Central Valley, which is dire need of mobile source reduction in pollution, to move to EVs is almost an impossibility,” Florez says.
This new plan could help people like Jessi Fierro, who is a busy mother of two young children and with a typically packed family car.
“It’s kind of a mom mobile. I manage to keep the front pretty clear. But you will see in the back I have both my car seats ready to go,” Feirro says pointing to car seats in her car at her office.
She drives a Chevy Bolt. That’s an all-electric car with a range of about 230 miles, which for electric cars is really good. She is lucky because her office offers a charging station for her.
Still, Fierro says she is always aware of where the next charging station is and sometimes plans her trips around them.
“And when I have taken my longer trips out of town I am trying to find destinations close to chargers, just so the kids aren’t getting too fussy while I am charging my car. But for the most part, when I am putzing about town I know where a handful of charges are. And actually there are aps too for your phone so you can say ‘I am going to be here. Where are chargers nearby,’” Fierro asks.
Fierro says she has no regrets about going electric and rarely charges her car at home, preferring to find chargers in the wild.
Some possible sites for the new chargers include workplaces, grocery stores, public parks and big box retailers with their massive parking lots. The San Joaquin Valley Air Pollution Control District says they are working to convince, and financially incentivize, businesses to install the chargers for their employees and customers.
Frequent and convenient charging stations are perhaps the most critical part of the plan according to Jamie Holt with the San Joaquin Valley Air Pollution Control District.
“We need charging stations to be as prevalent throughout the valley as gas stations are now,” Holt says.
She says they are trying to change hearts and minds about the reliability of access to power for electric vehicles, especially for people who live in apartments or park on the street where at-home charging is not possible.
“We really want folks to feel like even though they can’t charge at home, they still will have the ability to charge out in the world. You know, you can’t put gas in your car at you home. Most people don’t have a gas station at their house. So it’s really it’s no different than that,” Holt says.
Holt says the more the cars saturate the market, the more likely it is people will become more comfortable with the idea of driving an electric car. She also says they are working to break the perception that electric cars are only something that rich people on the coast use.
To that end, she says there are a wealth of rebate and pre-bate programs, some that are income based, to help low and moderate income families go electric. And especially in the valley, those families could stand to the benefit the most.

More Americans are going to college than ever before. The most recent census found that 33.4 percent of adults over the age of 24 have earned a bachelor’s degree or more. Kurt Bauman, Chief of the Education and Social Stratification Branch for the U.S. Census describes this as, “a significant milestone” for the country.
For many, however, higher education remains a privilege that is financially inaccessible. One way students can invest in their futures without investing in a bachelor’s degree is through vocational education. By enrolling in vocational education programs, students can earn degrees in high-demand fields like nursing, business and engineering which can lead to high-paying jobs. Still, many students believe that a bachelor’s degree is the only path to success.
In order to change this, the state of California is spending $200 million to encourage more students to earn a vocational certificate instead of a bachelor’s degree.
The U.S. Government defines vocational education as, “organized educational programs offering a sequence of courses which are directly related to the preparation of individuals in paid or unpaid employment in current or emerging occupations requiring other than a baccalaureate or advanced degree.”
These programs, offered by community colleges across the country, are by definition designed to help students find employment. Reports from the U.S. Department of Education indicate that people with vocational education have slightly higher rates of employment than those with academic credentials. According to the Georgetown University Center on Education and the Workforce, there are over 30 million jobs that pay an average of $55,000 a year and do not require a bachelor’s degree. The healthcare industry alone is creating millions of high-paying jobs that don’t require students to study for four years.
Despite the benefits of vocational education, it has yet to appeal to American students on a broad scale. According to the National Center for Education Statistics, only 8 percent of undergraduates are enrolled in a vocational certificate program. Derrick Roberson, 17, tells PBS, “All throughout high school, they made it sound like going to college was our only option.” Today, Roberson is training to be an electrician.
In many regions, vocational programs have even declined in popularity. For instance, in 2000, 31 percent of community college students in California took vocational courses. Today, only 28 percent of students take these courses.
Experts believe that students hesitate to enter vocational training programs in part because of fears that industries like manufacturing will replace workers with robots. Business consultant Sam Geil told PBS, “It doesn’t help when industry is moving out and laying people off.”
Despite these fears, California is investing over $200 million in vocational education. Today, California Community Colleges is the largest provider of workforce training in the country. The state hopes to use the money to improve the reputation of vocational education and deliver it more effectively.
The New York Times points out that this kind of investment from the government helps corporations cut costs: “They want schools and, by extension, the government to take on more of the costs of training workers that used to be covered by companies as part of on-the-job employee development.” In other countries like Germany, companies are heavily involved in training workers.
Still, Andrew Hanson, a senior research analyst with Georgetown University’s Center on Education and the Workforce told Matt Krupnick, “Efforts like California’s to broaden the appeal are exactly what we need.”

• “The region is currently experiencing solid manufacturing growth”
The San Joaquin Valley Business Conditions Index, compiled by researchers at Fresno State University, has moved down, but still points to strong growth in the next three to six months.
“The region is currently experiencing solid manufacturing growth combined with upturns in regional construction,” says Ernie Goss, research faculty with the Craig School of Business at Fresno State. “However, as in past months, durable, or heavy manufacturing, continues to lag behind non-durable manufacturing, including food processing.”
The index is a leading economic indicator from a survey of individuals making company purchasing decisions for firms in the counties of Fresno, Kings, Madera and Tulare. It is produced using the same methodology as that of the national Institute for Supply Management.
“Over the past 12 months, the San Joaquin [Valley] region has experienced strong and improving job growth at 2.1 percent, which is well above the pace of the nation’s 1.5 percent,” says Mr. Goss.
• Wholesale Prices: The prices-paid index, which tracks the cost of purchased raw materials and supplies, slipped to 70.2 from 71.2 in July, indicating modest but elevated inflationary pressures at the wholesale level.
“I expect inflationary pressures at both the consumer and wholesale level to moderate in the months ahead. As a result, I expect the Federal Reserve to delay another rate hike until the end of the fourth quarter of 2017, or first quarter of 2018,” says Mr. Goss.
• Business Confidence: Looking ahead six months, economic optimism, as captured by the business confidence index, slipped to 65.3 from July’s 70.0.
• Inventories: In another show of economic confidence, the inventory index remained above growth neutral for August. The August inventory declined to 52.3 from 54.5 in July.
• Trade: The new export orders index fell to 46.9 from 53.8 in July while the import index dropped to 41.9 from July’s 48.1.
• Other components: Other components of the August Business Conditions Index were: new orders at 60.5, down from 67.1 in July; production or sales at 62.8, down from July’s 71.7; and delivery lead time at 61.4, up from last month’s 57.4.

Sungrow, the global leading PV inverter system solution supplier, announced that it would supply 205MW of central inverters for a utility-scale solar project in California’s Central Valley.
The Central Valley is home to many of California’s solar farms because of its abundant land space and frequent sunshine. It experiences high temperatures in the summer months, putting significant wear-and-tear on solar hardware. The power plant is expected to be completed in late 2017 using Sungrow’s newest 1500V turnkey central inverter solution, the SG2500U.
The product is designed for easy integration–with a containerized pre-integrated option also available–and simplified installation making it the ideal plug and play solution for utility-scale systems. For O&M, all serviceable components can be accessed externally, meaning lower repair times and service costs. In addition, the product is one of the first 1500V inverters be listed with the stringent UL 1741-SA certification required for most North American projects.
“Sungrow is always committed to technical innovation which drives our rapid growth. We will continue to offer better products and solutions to customers globally”, said Professor Renxian Cao.
The project signifies Sungrow’s rapid growth into North America, being the company’s largest project win in the continent since it entered the market in 2011. Earlier this year, the company announced it shipped an unprecedented 10.9 GW in the first half of 2017, moving up from its already impressive 11.1GW number for 2016.
Sungrow is a global leading inverter solution supplier for renewables with over 49GW installed worldwide as of June 2017. Founded in 1997 by University Professor Renxian Cao, Sungrow is a global leader in research and development in solar inverters, with numerous patents and a broad product portfolio offering PV inverter systems as well as energy storage systems for utility-scale, commercial, and residential applications.

The Central Valley Business Journal
Chances are, when you think of the Central Valley, you think about tomato trucks rumbling down the freeway or shakers knocking down almonds amidst endless rows of trees. You probably don’t think about modern tech companies or millennials working while sipping lattes in open, co-working spaces. But an ever-increasing group of local techies and entrepreneurs are working to change that.
Over the last few decades, the Central Valley’s tech community has been growing — slowly and under the radar. Local commuters working in Bay Area tech companies and tech-related professionals in Central Valley companies now number thousands across the region. Many software developers, often known as coders or hackers, have begun gathering at fun local events such as the Modesto-based Valley Hackathon (https://valleyhackathon.com/), a programming contest where Star Wars-costumed teams furiously write computer code to win thousands in cash and prizes.
Local business leaders who see the economic benefit tech jobs can bring to the region have also jumped in to accelerate the development of a tech community in the Central Valley. Launched several years ago, The Huddle is a co-working space in downtown Stockton which provides entrepreneurs a place to collaborate and create synergies to help each other’s companies grow. Tech startups in Sacramento now have communities like Hacker Lab where they can co-locate with other companies and get access to mentors and resources to improve revenue trajectory. In Fresno, Geekwise Academy has trained thousands of people to develop software over the past few years and its parent company, Bitwise Industries (http://bitwiseindustries.com/), has helped create over 1,000 tech-related jobs in the region. Bitwise now partners with Amazon to train developers on the latest platforms and eventually plans to occupy 2.5 million square feet of commercial space in downtown Fresno.
In Modesto, ValleyWorx, a tech and digital design co-working hub, will begin taking applications from tech companies and entrepreneurs later this month. One of its first tenants will be Bay Valley Tech (http://bayvalleytech.com/), a code academy focused on providing affordable hands-on software skills to working professionals and students preparing to enter the work force. Locating tech students and tech companies in the same building will allow students to more easily find internships and jobs. At the same time, companies based out of ValleyWorx will have access to an ever-expanding talent pool proficient in the latest technologies.
You may be wondering how all of these “geeks” are going to help the rest of our non-tech economy. By creating a thriving tech community in the Central Valley, we will make it a more attractive place for software professionals to settle.
Senior software engineers in California now earn an average salary of $129,000, and some make over $200,000 annually, according to Indeed.com. Not only will ‘hackers’ infuse disposable income into our local economy, their presence will attract Bay Area firms looking for tech talent.
For example, Oportun, a Redwood City-based venture-backed company, set up a software development office in downtown Modesto two years ago and is already outgrowing their space due to rapid hiring. Their executives indicated availability of software talent as a key driver for expanding into the Central Valley.
Other Bay Area companies are also considering expanding to Sacramento, Stockton and Modesto due to the availability of high-tech talent.
In order to continue the momentum and attract even more tech companies to the Central Valley, local businesses, non-profits and government entities are working to do the following:
The creation of a growing tech-enabled workforce will make the Central Valley an attractive investment destination for Bay Area tech companies who are now overlooking this region and expanding out of state to cities such as Austin, Denver, Seattle and Portland.The Central Valley needs more high-paying jobs, local residents need a realistic path into software-related careers to prepare for the changing world and Bay Area tech workers need affordable housing.
According to a recent poll by the Bay Area Council, a staggering 46 percent of millennials (people age 18 to 39) living in the San Francisco Bay Area say they’re now ready to leave one of the nation’s most unaffordable housing markets. Many have already left California, expanding the tech talent pool in other states.
As high paying software job openings continue to outpace the supply of programmers in California, this is the perfect time for Central Valley leaders to come together and create a win-win-win solution. A tech ecosystem generating exciting, well-paying jobs will also encourage local students to participate in junior high, high school and college programming and robotics initiatives.
Jumpstarting a tech economy in our ag-focused Central Valley is undoubtedly a Herculean task requiring a community-wide effort. Here are a few opportunities for business and community leaders who would like to help:

In a corner of Alphabet’s campus, there is a team working on a piece of software that may be the key to self-driving cars. No journalist has ever seen it in action until now. They call it Carcraft, after the popular game World of Warcraft.
The software’s creator, a shaggy-haired, baby-faced young engineer named James Stout, is sitting next to me in the headphones-on quiet of the open-plan office. On the screen is a virtual representation of a roundabout. To human eyes, it is not much to look at: a simple line drawing rendered onto a road-textured background. We see a self-driving Chrysler Pacifica at medium resolution and a simple wireframe box indicating the presence of another vehicle.
If Waymo can deliver fully autonomous vehicles in the next few years, Carcraft should be remembered as a virtual world that had an outsized role in reshaping the actual world on which it is based.
Originally developed as a way to “play back” scenes that the cars experienced while driving on public roads, Carcraft, and simulation generally, have taken on an ever-larger role within the self-driving program.
At any time, there are now 25,000 virtual self-driving cars making their way through fully modeled versions of Austin, Mountain View, and Phoenix, as well as test-track scenarios. Waymo might simulate driving down a particularly tricky road hundreds of thousands of times in a single day. Collectively, they now drive 8 million miles per day in the virtual world. In 2016, they logged 2.5 billion virtual miles versus a little over 3 million miles by Google’s IRL self-driving cars that run on public roads. And crucially, the virtual miles focus on what Waymo people invariably call “interesting” miles in which they might learn something new. These are not boring highway commuter miles.
To get to Castle, you drive east from San Francisco Bay and south on 99, the Central Valley highway that runs south to Fresno. Cornfields abut subdevelopments; the horizon disappears behind agricultural haze. It’s 30 degrees hotter than San Francisco and so flat that the grade of this “earthen sea,” as John McPhee called it, can only be measured with lasers. You exit near the small town of Atwater, once the home of the Castle Air Force Base, which used to employ 6,000 people to service the B-52 program. Now, it’s on the northern edge of the small Merced metro area, where unemployment broke 20 percent in the early 2010s, and still rarely dips below 10 percent. Forty percent of the people around here speak Spanish. We cross some railroad tracks and swing onto the 1,621 acres of the old base, which now hosts everything from Merced County Animal Control to the U.S. Penitentiary, Atwater.
The self-driving cars are easy to pick out. They’re studded with sensors. The most prominent are the laser scanners (usually called LIDARs) on the tops of the cars. But the Pacificas also have smaller beer-can-sized LIDARs spinning near their side mirrors. And they have radars at the back which look disturbingly like white Shrek ears.
When a car’s sensors are engaged, even while parked, the spinning LIDARs make an odd sound. It’s somewhere between a whine and a whomp, unpleasant only because it’s so novel that my ears can’t filter it out like the rest of the car noises that I’ve grown up with.
As we pull into the parking lot, there are whiffs of Manhattan Project, of scientific outpost, of tech startup. Inside the main building, a classroom-sized portable, I meet the motive force behind this remarkable place. Her name is Steph Villegas.
Villegas wears a long, fitted white collared shirt, artfully torn jeans, and gray knit sneakers, every bit as fashionable as her pre-Google job at the San Francisco boutique Azalea might suggest. She grew up in the East Bay suburbs on the other side of the hills from Berkeley and was a fine-arts major at University of California, Berkeley before finding her way into the self-driving car program in 2011.
“You were a driver?” I ask.
“Always a driver,” Villegas says.
She spent countless hours going up and down 101 and 280, the highways that lead between San Francisco and Mountain View. Like the rest of the drivers, she came to develop a feel for how the cars performed on the open road. And this came to be seen as an important kind of knowledge within the self-driving program. They developed an intuition about what might be hard for the cars. “Doing some testing on newer software and having a bit of tenure on the team, I began to think about ways that we could potentially challenge the system,” she tells me.
So, Villegas and some engineers began to cook up and stage rare scenarios that might allow them to test new behaviors in a controlled way. They started to commandeer the parking lot across from Shoreline Amphitheater, stationing people at all the entrances to make sure only approved Googlers were there.
These became the first structured tests in the self-driving program. It turns out that the hard part is not really the what-if-a-zombie-is-eating-a-person-in-the-road scenarios people dream up, but proceeding confidently and reliably like a human driver within the endless variation of normal traffic.
Villegas started gathering props from wherever she could find them: dummies, cones, fake plants, kids’ toys, skateboards, tricycles, dolls, balls, doodads. All of them went into the prop stash. (Eventually, the props were stored in a tent, and now at Castle, in a whole storage unit.)
They needed a base, a secret base. And that’s what Castle provided. They signed a lease and started to build out their dream fake city. “We made conscious decisions in designing to make residential streets, expressway-style streets, cul-de-sacs, parking lots, things like that,” she says, “so we’d have a representative concentration of features that we could drive around.”
We pull up to a large, two-lane roundabout. In the center, there is a circle of white fencing. “This roundabout was specifically installed after we experienced a multilane roundabout in Austin, Texas,” Villegas says. “We initially had a single-lane roundabout and were like, ‘Oh, we’ve got it. We’ve got it covered.’ And then we encountered a multi-lane and were like, ‘Horse of a different color! Thanks, Texas.’ So, we installed this bad boy.”
And then there are the test assistants, who they call “foxes,” a sobriquet that evolved from the word “faux.” They drive cars, create traffic, act as pedestrians, ride bikes, hold stop signs. They are actors, more or less, whose audience is the car.
The first test we’re gonna do is a “simple pass and cut-in,” but at high speed, which in this context means 45 miles per hour. We set up going straight on a wide road they call Autobahn.
After the fox cuts us off, the Waymo car will brake and the team will check a key data point: our deceleration. They are trying to generate scenarios that cause the car to have to brake hard. How hard? Somewhere between a “rats, not gonna make the light” hard stop and “my armpits started involuntarily sweating and my phone flew onto the floor” really hard stop.
Let me say something ridiculous: This is not my first trip in a self-driving vehicle. In the past, I’ve taken two different autonomous rides: first, in one of the Lexus SUVs, which drove me through the streets of Mountain View, and second, in Google’s cute little Firefly, which bopped around the roof of a Google building. They were both unremarkable rides, which was the point.
It’s time to go. Cain gets us moving and with a little chime, the car says, “Autodriving.” The other car approaches and cuts us off like a Porsche driver trying to beat us to an exit. We brake hard and fast and smooth. I’m impressed.
Then they check the deceleration numbers and realize that we had not braked nearly hard enough. We have to do it again. And again. And again. The other car cuts us off at different angles and with different approaches. They call this getting “coverage.”
Two cars merging at high speed, one driving itself (Alexis Madrigal)
We go through three other tests: high-speed merges, encountering a car that’s backing out of a driveway while a third blocks the autonomous vehicle’s view, and smoothly rolling to a stop when pedestrians toss a basketball into our path. Each is impressive in its own way, but that cut-off test is the one that sticks with me.
As we line up for another run, Cain shifts in his seat. “Have you ever seen Pacific Rim?” Cain asks me. You know the Guillermo del Toro movie where the guys get synced up with huge robot suits to battle monsters. “I’m trying to get in sync with the car. We share some thoughts.”
I ask Cain to explain what he actually means by syncing with the car. “I’m trying to adjust to the weight difference of people in the car,” he says. “Being in the car a lot, I can feel what the car is doing—it sounds weird, but—with my butt. I kinda know what it wants to do.”
Far from the haze and heat of Castle, there is Google’s comfy headquarters in Mountain View. I’ve come to visit Waymo’s engineers, who are technically housed inside X, which you may know as Google X, the long-term, high-risk research wing of the company. In 2015, when Google restructured itself into a conglomerate called Alphabet, X dropped the Google from its name (their website is literally X.company). A year after the big restructuring, X/Alphabet decided to “graduate” the autonomous vehicle program into its own company as it had done with several other projects before, and that company is Waymo. Waymo is like Google’s child, once removed, or something.
So, Waymo’s offices are still inside the mother ship, though, like two cliques slowly sorting themselves out, the Waymo people all sit together now, I’m told.
The X/Waymo building is large and airy. There are prototypes of Project Wing’s flying drones hanging around. I catch a bit of the cute little Firefly car the company built. (“There’s something sweet about something you build yourself,” Villegas had said back at Castle. “But they had no A/C, so I don’t miss them.”)
Up from the cafeteria, tucked in a corner of a wing, is the Waymo simulation cluster. Here, everyone seems to have Carcraft and XView on their screens. Polygons on black backgrounds abound. These are the people creating the virtual worlds that Waymo’s cars drive through.
Waiting for me is James Stout, Carcraft’s creator. He’s never gotten to speak publicly about his project and his enthusiasm spills out. Carcraft is his child.
Back then, they primarily used the tool to see what their cars would have done in tricky situations in which human drivers have taken over control of the car. And they started making scenarios from these moments. “It quickly became clear that this was a really useful thing and we could build a lot out of this,” Stout says. The spatial extent of Carcraft’s capabilities grew to include whole cities, the number of cars grew into a huge virtual fleet.
Stout brings in Elena Kolarov, the head of what they call their “scenario maintenance” team to run the controls. She’s got two screens in front of her. On the right, she has up XView, the screen that shows what the car is “seeing.” The car uses cameras, radar, and laser scanning to identify objects in its field of view—and it represents them in the software as little wireframe shapes, outlines of the real world.
Green lines run out from the shapes to show the possible ways the car anticipates the objects could move. At the bottom, there is an image strip that displays what the regular (i.e., visible-light) cameras on the car captured. Kolarov can also turn on the data returned by the laser scanner (LIDAR), which is displayed in orange and purple points.
There is one key difference: In the real world, they have to take in fresh, real-time data about the environment and convert it into an understanding of the scene, which they then navigate. But now, after years of work on the program, they feel confident that they can do that because they’ve run “a bunch of tests that show that we can recognize a wide variety of pedestrians,” Stout says.
So, for most simulations, they skip that object-recognition step. Instead of feeding the car raw data it has to identify as a pedestrian, they simply tell the car: A pedestrian is here.
At the four-way stop, Kolarov is making things harder for the self-driving car. She hits V, a hot key for vehicle, and a new object appears in Carcraft. Then she mouses over to a drop-down menu on the righthand side, which has a bunch of different vehicle types, including my favorite: bird_squirrel.
Once they have the basic structure of a scenario, they can test all the important variations it contains. So, imagine, for a four-way stop, you might want to test the arrival times of the various cars and pedestrians and bicyclists, how long they stop for, how fast they are moving, and whatever else. They simply put in reasonable ranges for those values and then the software creates and runs all the combinations of those scenarios.
They call it “fuzzing,” and in this case, there are 800 scenarios generated by this four-way stop. It creates a beautiful, lacy chart—and engineers can go in and see how different combinations of variables change the path that the car would decide to take.
Here we see a video that shows exactly such a situation. It’s a complex four-way stop that occurred in real life in Mountain View. As the car went to make a left, a bicycle approached, causing the car to stop in the road. Engineers took that class of problem and reworked the software to yield correctly. What the video shows is the real situation and then the simulation running atop it. As the two situations diverge, you’ll see the simulated car keep driving and then a dashed box appear with the label “shadow_vehicle_pose.” That dashed box shows what happened in real life. To Waymo people, this is the clearest visualization of progress.
“That iteration cycle is tremendously important to us and all the work we’ve done on simulation allows us to shrink it dramatically,” Dolgov told me. “The cycle that would take us weeks in the early days of the program now is on the order of minutes.”
Well, I asked him, what about oil slicks on the road? Or blown tires, weird birds, sinkhole-sized potholes, general craziness. Did they simulate those? Dolgov was sanguine. He said, sure, they could, but “how high do you push the fidelity of the simulator along that axis? Maybe some of those problems you get better value or you get confirmation of your simulator by running a bunch of tests in the physical world.” (See: Castle.)
The power of the virtual worlds of Carcraft is not that they are a beautiful, perfect, photorealistic renderings of the real world. The power is that they mirror the real world in the ways that are significant to the self-driving car and allow it to get billions more miles than physical testing would allow. For the driving software running the simulation, it is not like making decisions out there in the real world. It is the same as making decisions out there in the real world.
And it’s working. The California DMV requires that companies report the miles that they’ve driven autonomously each year along with disengagements that test drivers make. Not only has Waymo driven three orders of magnitude more miles than anyone else, but their number of disengagements have fallen quickly.
While everyone takes pains to note that these are not exactly apples-to-apples numbers, let’s be real here: These are the best comparisons we’ve got and in California, at least, everybody else drove about 20,000 miles. Combined.
The tack that Waymo has taken is not surprising to outside experts. “Right now, you can almost measure the sophistication of an autonomy team—a drone team, a car team—by how seriously they take simulation,” said Chris Dixon, a venture capitalist at Andreessen Horowitz who led the firm’s investment in the simulation company Improbable. “And Waymo is at the very top, the most sophisticated.”
I asked Allstate Insurance’s head of innovation, Sunil Chintakindi, about Waymo’s program. “Without a robust simulation infrastructure, there is no way you can build [higher levels of autonomy into vehicles].” he said. “And I would not engage in conversation with anyone who thinks otherwise.”
Other self-driving car researchers are also pursuing similar paths. Huei Peng is the director of Mcity, the University of Michigan’s autonomous- and connected- vehicle lab. Peng said that any system that works for self driving cars will be “a combination of more than 99 percent simulation plus some carefully designed structured testing plus some on-road testing.”
He and a graduate student proposed a system for interweaving road miles with simulation to rapidly accelerate testing. It’s not unlike what Waymo has executed. “So what we are arguing is just cut off the boring part of driving and focus on the interesting part,” Peng said. “And that can let you accelerate hundreds of times: A thousand miles becomes a million miles.”
And in reality, those 20,000 scenarios only represent a fraction of the total scenarios that Waymo has tested. They’re just what’s been created from structured tests. They have even more scenarios than that derived from public driving and imagination.
“They are doing really well,” Peng said. “They are far ahead of everyone else in terms of Level Four,” using the jargon shorthand for full autonomy in a car.
But Peng also presented the position of the traditional automakers. He said that they are trying to do something fundamentally different. Instead of aiming for the full autonomy moon shot, they are trying to add driver-assistance technologies, “make a little money,” and then step forward toward full autonomy. It’s not fair to compare Waymo, which has the resources and corporate freedom to put a $70,000 laser range finder on top of a car, with an automaker like Chevy that might see $40,000 as its price ceiling for mass-market adoption.
And even just within the race for full autonomy, Waymo now has more challengers than it used to, Tesla in particular. Chris Gerdes is the director of the Center for Automotive Research at Stanford. Eighteen months ago, he told my colleague Adrienne LaFrance that Waymo “has much greater insight into the depth of the problems and how close we are [to solving them] than anyone else.” When I asked him last week if he still thought that was true, he said that “a lot has changed.”
“Auto manufacturers such as Ford and GM have deployed their own vehicles and built on-road data sets,” he said. “Tesla has now amassed an extraordinary amount of data from Autopilot deployment, learning how the system operates in exactly the conditions its customers experience. Their ability to test algorithms on board in a silent mode and their rapidly expanding base of vehicles combine to form an amazing testbed.”
In the realm of simulation, Gerdes said that he had seen multiple competitors with substantial programs. “I am sure there is quite a range of simulation capabilities but I have seen a number of things that look solid,” he said. “Waymo no longer looks so unique in this respect. They certainly jumped out to an early lead but there are now a lot of groups looking at similar approaches. So it is now more of a question of who can do this best.”
Waymo seems like it has driving as a technical skill—the speed and direction parts of it—down. It is driving as a human social activity that they’re working on now. What is it to drive “normally,” not just “legally”? And how does one teach an artificial intelligence what that means?
It turns out that building this kind of artificial intelligence does not simply require endless data and engineering prowess. Those are necessary, but not sufficient. Instead, building this AI requires humans to sync with the cars, understanding the world as they do. As much as anyone can, the drivers out at Castle know what it is to be one of these cars, to see and make decisions like them. Maybe that goes both ways, too: The deeper humans understand the cars, the deeper the cars understand humans.
A memory of a roundabout in Austin becomes a piece of Castle becomes a self-driving car data log becomes a Carcraft scenario becomes a web of simulations becomes new software that finally heads back out on a physical self-driving car to that roundabout in Texas.
Even within the polygon abstraction of the simulation the AI uses to know the world, there are traces of human dreams, fragments of recollections, feelings of drivers. And these components are not mistakes or a human stain to be scrubbed off, but necessary pieces of the system that could revolutionize transportation, cities, and damn near everything else.

Merced County is in the process of developing a 2,000-acre site encompassing the former Castle Air Force Base, which it hopes will become the center for testing, development and manufacturing of automotive technology, including for many of the self-driving cars being developed in Silicon Valley.
Adam Wasserman, managing partner of Scottsdale, Arizona-based GLDPartners, which consults with international companies on optimizing their supply chains, said the project expects to announce its first tenant — likely linked to Silicon Valley’s R&D efforts on autonomous driving R&D — by early fall.

Google is already using a 91-acre site for its own autonomous car testing program adjacent to the planned Mid-California AutoTech Testing, Development and Production Campus, county officials said.
At full build-out, the development plan calls for 8 million square feet of industrial space employing about 9,300 people.
“It just puts us on that technology map that everybody in Silicon Valley is enjoying,” said Daron McDaniel, chair of the county’s board of supervisors.
Merced County hired GLDPartners after several failed attempts to commercialize the Castle property, which it took ownership of in 2006 following the air base’s 1995 closure.
The county’s median family income was about $43,000 in 2016, about 80 percent of the national median, and about a quarter of its 262,000 residents live below the poverty line, according to census figures.
Before settling on auto technology, the company researched several other business sectors including food production, medical products, commercial space systems, industrial machines and specialty chemicals based on how they might fit in those sectors’ supply chains.
“The project takes advantage of the dire lack of testing facilities anywhere in the country, much less in California, where much of the research that is shaping the global auto industry is now taking place,” Wasserman wrote in an email.
The site works because of the concentration of international auto tech research in Silicon Valley, the proximity of Bay Area universities and 13-year-old UC Merced, which is forecast to double its enrollment to 14,000 students within three years and already has solar energy and drone facilities at Castle.
That is coupled with transportation infrastructure including an airfield capable of handling the largest cargo planes and two major railroads connected to ports in Stockton and Oakland so that the site can handle manufacturing as well as testing.
The county is securing $200 million to connect the site to State Route 99 by a road to be called the Atwater-Merced Expressway.
“We strongly believe — and it’s obviously been evidenced by Google and the work they do onsite with their autonomous vehicle program — we’re going to be incredibly competitive in the auto tech sector,” said Mark Hendrickson, the county’s economic development director.
Part of the site was originally pitched by the county to California high-speed rail officials for the system’s heavy maintenance facility, which is to be located in the San Joaquin Valley, but McDaniel said there has been no indication when they would make a decision.
“If high-speed rail wants us they need to pull the trigger right away,” he said.

Technology giant Google has entered a lease agreement with Merced County to use 60 acres of land at Castle Commerce Center to help develop the company’s self-driving car technology, the Sun-Star has learned.
Google officials confirmed the lease agreement Friday morning after speculation about who was going to be using the property at Castle. In late December, the Board of Supervisors approved the lease agreement with Google.
It wasn’t immediately clear until Friday that Google was behind the project because the company is listed in the lease agreement document under the name LRC Engineering LLC.
Katelin Jabbari, Google spokeswoman, confirmed her company will be using the Castle site. “It’s a nice space, and we’re happy to be there,” Jabbari said.
Regarding Google’s self-driving car technology, Jabbari also wrote in an email: “We’ve successfully driven in self-driving mode across a wide variety of terrain and road conditions — including a loop around Lake Tahoe and through the Santa Cruz Mountains — and we’re very pleased with the technology’s performance.”
“We’re continuing to develop and refine the technology in a variety of environments, including closed tracks where we can set up challenging courses and obstacles — and the space available to us at Castle is very helpful for that,” Jabbari added.
Mark Hendrickson, director of community and economic development, said the site, referred to as Building 175, includes the old flight simulator facility from the property’s days as Castle Air Force Base.
Google will lease the space for two years for $456,000, according to county documents. The lease payments are about $19,000 a month, beginning in May 2014.
Many details about the project are still preliminary, and it still remains to be seen how many new jobs the project will mean in the immediate future for Merced County residents. Jabbari said she could not comment on how many jobs could be added.
Hendrickson said Google will bring about 10 to 15 people to work at the site. He said the long-term implications for the agreement are very positive, particularly with the contractors, engineers and ancillary spin-off projects associated with the endeavor.
Hendrickson said the deal represents one of the most important moments in the county’s recent development history. “With Google, they represent the future, and we are so pleased to have a good relationship with them, and so pleased they chose Castle and Merced County to launch this venture,” Hendrickson said.
He said talks between county officials and Google began about six months ago.
Crews are currently preparing the site, enveloping it with fencing and getting the building ready for use. The company plans site improvements to build a low-speed closed course for vehicle testing. The company will use the area for the “operation and testing of motor vehicles,” according to county documents.
Google’s project lead Chris Urmson worked on some of the very earliest self-driving car projects, according to Jabbari. Prior to joining Google, Urmson and his teams tested their vehicles at Castle. “So he knew it was a great community to work in,” Jabbari said.

Dan Hirleman, dean of UC Merced’s school of engineering, said Google’s announcement about the project could have positive ramifications in the long term. He’s also hopes the development will lead to future technology opportunities for UC Merced students.
“A company that high profile globally having a footprint here is huge for UC Merced and huge for Merced and the region,” he said.
Hirleman is also familiar with self-driving car technology, having worked on a team that tried to qualify in the Defense Research Project Agency’s (DARPA) Grand Challenge. DARPA Grand Challenge is a competition involving autonomous vehicles. “I’ve ridden in these cars myself. (The technology) is here. How we adapt (the cars) to the laws of the road is probably the main question, and how we deal with the liability,” he said.
Stefano Carpin, UC Merced engineering professor, said it will be great inspiration for his students to know the tech giant is holding court in their backyard.
Carpin, who holds a doctorate in robotics, established UC Merced’s robotics lab in 2007. The campus is also developing unmanned aerial vehicles at Castle, not far from where the Google site will be located. “It’s great that they are very near and training here in the county.”
Carpin said the amount of progress that has been made on self-driving cars has been “tremendous” over the years, with research taking place in the United States and Europe. Carpin said it won’t be long before self-driving cars are a familiar sight for the average person. “A major stumbling block is how do we put them in a legal framework so we are all safe with having these vehicles around?” Carpin said.
Merced Mayor Stan Thurston, who is also co-president of Gemini Flight Support, the airport’s fixed-base operator, said he suspected something might be in the works a few months ago when a few Google employees turned up at Castle.
Thurston said the Google employees were at Castle to take a driving class and written test, which is required in order to drive vehicles on the airport side of the center.
“The footprint they are going to use immediately screamed ‘driver-less car,’” Thurston said. “Obviously we’re very excited to have them here.”
Thurston also expressed high hopes that UC Merced professors and students might eventually be able to collaborate with Google, as a result of the project. “We’ve got a high-tech company and a high-tech university, and I just can’t believe that those two aren’t going to start dating each other. At least I would hope that would happen,” Thurston said.
Castle Airport and Commerce Center covers 1,912 acres in Atwater, 450 acres of which have non-airport uses.

It has updated its “Census Flows Mapper” to include data from the 2011-2015 American Community Survey. Census Flows Mapper is a web mapping application that allows users to view and save county-to-county migration flows in the United States. Users can sort and customize maps by dataset, type of migration flow, colors and range of movers.
Each dataset features different characteristics using five-year American Community Survey data. The updated tables cover migration flows between counties by selected characteristics including sex, age, race and Hispanic origin. Additional characteristics such as household income, educational attainment and employment statistics are available in previous datasets.
