US SEEKS INFORMATION FROM TESLA ON HOW IT DEVELOPED AND VERIFIED WHETHER AUTOPILOT RECALL WORKED

Federal highway safety investigators want Tesla to tell them how and why it developed the fix in a recall of more than 2 million vehicles equipped with the company’s Autopilot partially automated driving system.

Investigators with the U.S. National Highway Traffic Safety Administration have concerns about whether the recall remedy worked because Tesla has reported 20 crashes since the remedy was sent out as an online software update in December.

The recall fix also was to address whether Autopilot should be allowed to operate on roads other than limited access highways. The fix for that was increased warnings to the driver on roads with intersections.

But in a letter to Tesla posted on the agency’s website, investigators wrote that they could not find a difference between warnings to the driver to pay attention before the recall and after the new software was released. The agency said it will evaluate whether driver warnings are adequate, especially when a driver-monitoring camera is covered.

Phil Koopman, a professor at Carnegie Mellon University who studies automated driving safety, said the letter shows that the recall did little to solve problems with Autopilot and was an attempt to pacify NHTSA, which demanded the recall after more than two years of investigation.

“It’s pretty clear to everyone watching that Tesla tried to do the least possible remedy to see what they could get away with,” Koopman said. “And NHTSA has to respond forcefully or other car companies will start pushing out inadequate remedies.”

Safety advocates have long expressed concern that Autopilot, which can keep a vehicle in its lane and a distance from objects in front of it, was not designed to operate on roads other than limited access highways.
