A Florida jury has found Tesla partially liable in a fatal crash involving its Autopilot system, ordering the Elon Musk-owned company to pay $329 million in damages. The verdict marks a major legal blow for Tesla and a significant moment in the broader debate over the safety of autonomous driving technology.

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.

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.
