Amazon’s self-driving robotaxi unit Zoox under investigation by US after 2 rear-end crashes WHIO TV 7 and WHIO Radio [Video]

DETROIT — (AP) — Amazon’s self-driving robotaxi unit is being investigated by the U.S. government’s highway safety agency after two of its vehicles braked suddenly and were rear-ended by motorcyclists.

The National Highway Traffic Safety Administration said in documents posted on its website Monday it will evaluate the automated driving system developed by Zoox.

Both crashes involved Toyota Highlander SUVs with autonomous driving technology. They happened during daytime hours, and the agency confirmed that each of the Amazon vehicles was operating in autonomous mode leading up to the crashes. In one crash a motorcyclist suffered minor injuries, and a Zoox driver reported minor injuries in the other, according to reports. Both happened last month, one in San Francisco and the other in Spring Valley, Nevada.

The agency said the probe will focus on the performance of the company’s automated driving system during the crashes, as well as how it behaves in crosswalks around pedestrians and other vulnerable road users.
