2025 TESLA MODEL 3 Forward Collision Avoidance Warnings Problems

On [XXX] at approximately [XXX], I was driving northbound on [XXX] in Phoenix, Arizona in my 2025 Tesla Model 3 using Tesla's Full Self Driving (FSD) (Supervised) mode, when the incident occurred. I was paying close attention while driving in the left-most, non-HOV lane coming up to a bend just before the [XXX] overpass, when I noticed traffic ahead slowing down and coming to a stop. I monitored FSD as it went through the act of braking; however, it seemed to wait a little longer than I would have expected before it actually started to brake, and when it did, the FSD system had to brake more aggressively than I've previously experienced. As it neared the end of the braking event (while the car was still moving), the FSD system disengaged itself without any input from me (neither by manually applying the brake pedal, applying torque to the steering wheel,...

2025 Tesla Model 3 the follow distance is too close to front vehicle (only 1 to 2 car lengths) while in full self driving mode and there is no way to adjust it like in cruise control mode. Also, while in auto cruise control or full self driving the forward collision warning has too many false alarms from overhead tree branches to nothing in front of car for more than 500 feet. Finally, the car takes turns too late and at unsafe speeds when autosteer and cruise control are both activated. This also happens during Full Self driving.

I was using full self driving (FSD) and there was no one directly in front of me and thankfully no one behind me when it engaged its emergency brakes and came to an abrupt stop for no reason.
