> A dumb setting that fixes velocity is not the same, in any way, as a sophisticated self-driving mechanism that aims to recognize the world around it and adjust multiple parameters dynamically.

Except plenty of modern cars don't just have fixed velocity cruise control. They have adaptive cruise control that will speed up or slow down to match the velocity of the car ahead of you. They also have lane centering that will keep your car in its lane. That sounds an awful lot like Teslas.
