The United States National Highway Traffic Safety Administration (NHTSA) said it is opening an investigation after a Waymo self-driving vehicle struck a child near an elementary school in Santa Monica, California, last week, causing minor injuries and renewing concerns about the safety of robotaxis. The car safety agency said on Thursday that the child ran across the street on January 23 from behind a double-parked SUV towards the school and was struck by the Alphabet-unit Waymo autonomous vehicle during normal school drop-off hours. The agency said there were other children, a crossing guard, and several double-parked vehicles in the vicinity. The US Senate Commerce Committee had already scheduled a hearing on self-driving cars for February 4, which will include Waymo Chief Safety Officer Mauricio Pena. The National Transportation Safety Board (NTSB) also said it will investigate the incident.

US safety officials opened a preliminary investigation into Tesla's Autopilot after identifying 11 crashes involving the driver assistance system, officials said Monday. The incidents dating back to 2018 included one fatal crash and seven that resulted in injuries, according to the National Highway Traffic Safety Administration. Tesla founder Elon Musk has defended the Autopilot system and the electric automaker warns that it requires "active driver supervision" behind the wheel, but critics, including in Congress, say the system can be easily fooled and have called for NHTSA to take action. Testers with the magazine Consumer Reports demonstrated in a video that Autopilot could be fooled into driving with nobody behind the wheel, an exercise also shown in widely-seen videos on Tik-Tok and other social media platforms. "A preliminary evaluation starts the agency's fact-finding mission and allows additional information and data to be collected," a NHTSA spokesperson said.
