Autopilot is completely different software from FSD. If you think FSD is stupid then Autopilot is worse because it won't do anything other than stay in the same lane and adjust speed to the car in front of you.

For some reason you could turn this on when you're not driving on the highway. It doesn't do anything for traffic lights, stop signs, obstacles, etc. because it's just cruise control. It's also included with every vehicle (unlike FSD).
