A Miami jury decided that Elon Musk’s car company Tesla was partly responsible for a deadly crash in Florida involving its Autopilot driver assist technology and must pay the victims more than $240 million in damages.

A federal court jury found Tesla partly liable on Friday in a 2019 car crash that killed a pedestrian and left another person badly injured when the car was in Autopilot mode.

The jury verdict is one of the first major legal decisions about driver assistance technology that has gone against Tesla. Both Elon Musk and Tesla have spent years making claims about Autopilot's capabilities.
