A federal jury in Miami found Tesla Inc. 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 driver, George Brian McGee, was using Tesla’s Autopilot driver-assistance system when his Model S sped through a stop sign at about 62 mph after he looked away to retrieve a dropped mobile phone. Jurors concluded the vehicle was sold with a defect that was a legal cause of the victims’ injuries, assigning one-third of the blame to Tesla and the remainder to the driver. They awarded $129 million in compensatory damages and $200 million in punitive damages, bringing the total verdict to $329 million. Because liability was apportioned, Tesla is expected to pay roughly $243 million—one of the largest sums ever imposed on the company over its driver-assistance technology. Plaintiffs argued Tesla failed to restrict Autopilot to highways for which it was designed and overstated the system’s capabilities. Tesla countered that no 2019-era vehicle could have prevented the crash and said the driver’s admitted distraction caused the collision. The company said it will appeal, calling the verdict legally flawed. The decision marks the first time a jury has held Tesla liable in an Autopilot wrongful-death case and could encourage additional litigation as the automaker seeks to expand self-driving features and roll out a planned robotaxi service.
