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.
