A federal jury in Miami ordered Tesla Inc. to pay $329 million after finding the company’s Autopilot driver-assistance system partly responsible for a 2019 crash in Key Largo, Florida, that killed 22-year-old Naibel Benavides Leon and seriously injured her boyfriend, Dillon Angulo. The panel awarded $129 million in compensatory damages and $200 million in punitive damages, assigning one-third of the liability to Tesla and two-thirds to the Model S driver, George McGee, who testified he was distracted by a dropped mobile phone and believed Autopilot would brake automatically. The verdict is the first in which a jury has held Tesla liable in a wrongful-death case involving its driver-assistance technology. Plaintiffs argued Tesla marketed Autopilot as safer than it is and failed to restrict its use to highways, allowing the car to speed through a stop sign at about 60 mph. Tesla countered that no vehicle available in 2019 could have prevented the collision and said the driver’s inattention was the primary cause. Tesla said it will appeal the decision, calling the verdict “wrong” and warning it could slow adoption of life-saving technology. The ruling may open the door to additional lawsuits over driver-assist systems as Chief Executive Officer Elon Musk pushes plans for robotaxi services. Tesla shares fell roughly 2% to $301.90 following the announcement.
