Tesla was found partially liable in a wrongful death lawsuit in a federal court in Miami today. It's the first time that a jury has found against the car company in a wrongful death case involving its Autopilot driver assistance system—previous cases have been dismissed or settled.

In 2019, George McGee was operating his Tesla Model S using Autopilot when he ran past a stop sign and through an intersection at 62 mph then struck a pair of people stargazing by the side of the road. Naibel Benavides was killed and her partner Dillon Angulo was left with a severe head injury.

While Tesla said that McGee was solely responsible, as the driver of the car, McGee told the court that he thought Autopilot "would assist me should I have a failure or should I miss something, should I make a mistake," a perception that Tesla and its CEO Elon Musk has done much to foster with highly misleading statistics that paint an impression of a brand that is much safer than in reality.

The jury heard from expert witnesses about Tesla's approach to human-machine interfaces and driver monitoring, as well as its use of statistics, then considered their verdict on Thursday afternoon and Friday before deciding that, while McGee was partly responsible for the crash, so too was Tesla, which sold a vehicle "with a defect that was a legal cause of damage" to Benavides' relatives and Angulo. The jury awarded the plaintiffs $129 million in compensatory damages, and a further $200 million in punitive damages.

"Tesla designed autopilot only for controlled access highways yet deliberately chose not to restrict drivers from using it elsewhere, alongside Elon Musk telling the world Autopilot drove better than humans," said Brett Schreiber, lead attorney for the plaintiffs. "Tesla’s lies turned our roads into test tracks for their fundamentally flawed technology, putting everyday Americans like Naibel Benavides and Dillon Angulo in harm's way. Today's verdict represents justice for Naibel's tragic death and Dillon's lifelong injuries, holding Tesla and Musk accountable for propping up the company’s trillion-dollar valuation with self-driving hype at the expense of human lives," Schreiber said.

Ars emailed Tesla for a comment but has not had a reply to a PR enquiry from the company for many years.
