Virginia authorities have determined that a Tesla was operating on its Autopilot system and was speeding in the moments leading to a crash with a crossing tractor-trailer last July that killed the Tesla driver. The death of Pablo Teodoro III, 57, is the third since 2016 in which a Tesla that was using Autopilot ran underneath a crossing tractor-trailer, raising questions about the partially automated system's safety and where it should be allowed to operate. The crash south of Washington remains under investigation by the U.S. National Highway Traffic Safety Administration, which sent investigators to Virginia last summer and began a broader probe of Autopilot more than two years ago.

The sun had yet to rise in Delray Beach, Fla., when Jeremy Banner flicked on Autopilot. His red Tesla Model 3 sped down the highway at nearly 70 mph, his hands no longer detected on the wheel. Seconds later, the Tesla plowed into a semi-truck, shearing off its roof as it slid under the truck's trailer. Banner was killed on impact. Banner's family sued after the gruesome 2019 collision, one of at least 10 active lawsuits involving Tesla's Autopilot, several of which are expected to go to court over the next year. Together, the cases could determine whether the driver is solely responsible when things go wrong in a vehicle guided by Autopilot -- or whether the software should also bear some of the blame.
