NHTSA Complaint #11703481 — 2021 TESLA MODEL Y

Tesla's Full Self Driving (FSD) stopped my car on trolley tracks today, and would have stayed on the tracks for a minute if I hadn't taken control and driven off the tracks. This occurred in downtown San Diego, where the trolley (light rail) has many level street crossings. They are well marked. You are not supposed to enter the zone around the tracks until the vehicle ahead of you has moved far enough for you to be able to cross the tracks and get safely past them. I was using FSD. It drove my Tesla onto the tracks before the car ahead of me had given me room to get off the tracks. The line of traffic was stopped for a red light. I would not have been able to drive forward until the light changed, perhaps over a minute. So, I took over and manually drove the car into the adjacent lane, which luckily was empty, and off the tracks. If a train had come while FSD was still in control, this would have killed me, and perhaps other nearby people. There was no warning message or other indicator.
