Agree with comments about FSD being a catch-all dumb thing but, as a subset, two items are probably tied for dumbest choice by programmers:
1) Forcing the screen brightness up when AP (not just FSD anymore) is engaged - purportedly to provide light for the internal camera to confirm driver is paying attention but, with dark mode, only serves to reduce night vision.
2) Forcing the wipers on (auto or other) during AP (not just FSD anymore) which means the confused camera could be running wipers on a dry windshield dragging muck around to diminish visibility while the distracted driver tries in vain to shut it off only to discover it can’t be done without disabling almost (not TACC) all driver assist features.
Oh, and runner up, Sentry Mode flashing/recording when the person with the Bluetooth enabled key approaches from the front of the car.
