DETROIT — 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.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.
Zoox said the vehicles had human safety drivers on board. The company reported the crashes under an order to automated vehicle companies issued in 2021. The company has launched a shuttle service exclusively for its employees. Analysts say they expect Amazon to use the Zoox system for autonomous deliveries.
