The 2026 Tesla model Y was driving in FSD (Supervised) mode in the Home Depot Colma, California parking lot, located at [XXX] on [XXX] at [XXX]. It stopped to let a black pickup truck in front of it pull about 3/4 of the way into a parking place on the right side. After waiting several seconds, it turned the wheels slightly to the left and slowly crept around the pickup truck, when the truck reversed and hit the passenger side of the vehicle at low speed just ahead of the rear wheel well. I believe a human driver would have waited until the pickup truck was fully parked before proceeding, thus preventing this accident, thus highlighting a failure of the FSD (Supervised) system. There were no warning lamps, messages or other symptoms of the problem prior to the failure, The accident was reported to my insurance company and the vehicle was inspected by a collision repair shop. The manufacturer has not been informed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
