Tesla's Autopilot was not at fault in a 2021 crash in which two people died, according to the National Transportation Safety Board (NTSB). In a final report spotted by Ars Technica, the agency determined that the 2019 Model S accelerated just before hitting a tree in Spring, Texas, just north of Houston. Neither occupant was in the driver's seat when they were found, leading to questions about the use of Autopilot.
