My gated community has a gate similar to a railroad gate. My FSD 12 HW3 model Y cannot be trusted at it. My FSD 14 HW4 Cybertruck does fine except if another car is in front of me. Then it tries to tailgate the car in. Strangely, the Y has the ultrasonic distance sensors and the cybertruck does not. The truck seems to be able to handle the gate detection but doesn’t understand the rule that only one car can go at a time.That being said, if I were first in line at a railroad crossing I think I’d disengage FSD to be safe. If I were in a Waymo I’d be very nervous. LiDAR or not, an error can be catastrophic.
