The Big Rig Next to You on Arizona Roads Might Be Driving Itself

Here's a new game for the kids on the boring drive between Tucson and Phoenix: Spot the big, green-and-white 18-wheelers driving by themselves.

Chinese autonomous vehicle maker TuSimple said on Monday it will roll out up to 40 fully self-driving tractor-trailers on Arizona roads by June. It's part of a test of the vehicles that has been going on since last year with about a dozen vehicles, and the company's ready to ramp up.

TuSimple, with headquarters in San Diego and Beijing, already has clients who pay to have the big rigs haul consumer goods. The new vehicles added to the fleet in Arizona will service routes to and from Phoenix and Tucson, from Nogales to Phoenix, and will soon run from Phoenix to El Paso, said TuSimple spokesman Robert Brown. The trucks run three to five times a day in Arizona.

The trucks' "camera-centric" detection system can see up to 1,000 meters, or about "30 seconds into the future," he said, adding that the driverless system is "always on, and doesn't get sleepy."

The trucks don't look all that different from a regular semi, except for the cameras above the cab. Most, though not all, have the attention-getting TuSimple logo.

"If you pay attention, you'll see us," Brown said.

The trucks have recently gained some experience in the rain, but are still limited mostly to daytime driving, he said.

Governor Doug Ducey touted the company in September when it expanded its Tucson testing facility and announced it would create 500 jobs in the state. The governor has made the state a haven for autonomous vehicle testing, declaring in 2016 that he wouldn't let regulation stand in the way. The policy became controversial after an Uber self-driving car killed a pedestrian in Tempe last year, and Uber pulled its program out of Arizona after Ducey ordered that it cease testing.

Google-affiliate Waymo has continued to test its self-driving cars heavily in the east Valley, and California-based Nuro recently began a test program delivering groceries to a small area in Scottsdale with fully driverless vehicles.

"Exactly one year after debuting our prototype system at CES 2018, we're now running up to five commercial trips a day in Arizona, expanding our fleet and moving quickly toward our goal of creating the first commercial self-driving truck," Xiaodi Hou, TuSimple's founder, president, and chief technology officer said in a statement on Monday.

Brown stresses that safety is a priority. For now, each semi-truck will have a backup driver and safety engineer inside.

TuSimple plans soon to reveal data collected by a third party to show how many times its self-driving trucks need intervention from the backup driver, which is expected to add credibility for the public, he said.

Waymo has yet to release its intervention data showing how cars driving in Chandler and other metro Phoenix locations are doing.
