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.
If one claims that an error at a railroad gate can be catastrophic and therefore FSD should be disabled in that situation, how does one ethically reconcile that with enabling FSD on any regular street with pedestrians?
The principal difference that comes to mind is that in the latter case it would be catastrophic to others as opposed to yourself: you are the train in that situation, except pedestrians have no airbags and without the railroad gate equivalent they are not made aware of taking this risk.
