The driver of a 2021 Tesla Model S told California authorities the vehicle was in "full self-driving mode" when the technology malfunctioned, causing an eight-vehicle crash on the San Francisco Bay bridge last month. The crash on Thanksgiving Day resulted in two juveniles being transported to hospital and led to lengthy delays on the bridge. The incident was made public in a police report on Wednesday. It is the latest in a series of accidents blamed on Tesla technology. The electric automaker's chief executive, Elon Musk, has heavily promoted "Full Self-Driving" (FSD) software, sold as $15,000 add-on to Tesla vehicles, but it faces legal, regulatory and public scrutiny.
