US seeks information from Tesla on how it developed and verified whether Autopilot recall worked
Federal safety investigators want Tesla to tell them how it developed the fix in a recall of more than 2 million vehicles with the company’s Autopilot partially automated driving system
DETROIT (AP) — Federal highway safety investigators want Tesla, Inc. (TSLA) 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.
In a l etter to Tesla posted on the agency's website Tuesday, 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 sent out. The agency said it will evaluate whether driver warnings are adequate, especially when a driver-monitoring camera is covered.
The agency asked for volumes of information about how Tesla developed the fix, and zeroed in on how the company used human behavior to test the recall effectiveness.
