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.

A Miami jury ordered Elon Musk’s car company on Friday to pay $329 million to victims of a deadly crash involving its Autopilot driver assist technology, opening the door to other costly lawsuits and striking a blow to Tesla’s reputation for safety.

The outcome is a stunning rebuke for Tesla, which for years has fought to absolve itself of responsibility when its technology is involved in a crash.
