Neither of those things were "learned adaptations" from human driving, and this is one of the biggest fallacies around FSD. People letting their FSD do stupid things and only intervening at the last moment (if at all) to let it learn from its mistakes.
That it might use the direction of the car in front of it as a guidance track doesn't mean it understood the human gestures of the cop telling it to do that. Or in a concert parking lot where an attendant might be doing things like alternating cars to the left and right lots.
> Because it copies human drivers, FSD actually was doing slow rolling stops for a while.
No, this was programmed behavior, with an interface/config setting, to do a "rolling stop". People "freaked out" because Tesla was literally allowing the car to perform illegal traffic infractions, and if they'd do it for stop signs, what else would they do it for?
But none of this is some Tesla "swarm" learning to do rolling stops. There is no adaptive learning happening. This is all trained from static models according to parameters from Tesla.
