Amazon's self-driving robotaxi unit Zoox under investigation by US after 2 rear-end crashes

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 that it will evaluate the automated driving system developed by Zoox. Both crashes happened during the daytime hours. The agency confirmed that each vehicle was operating in autonomous mode before the crashes. In one crash a motorcyclist suffered minor injuries, and a Zoox driver reported minor injuries in the other. Zoox says it's cooperating in the investigation.
