I test drove Tesla and specifically to test autopilot. I liked it less than Q7 automatic cruise control and line steering. In particular, to my taste Tesla was more/unnecessary aggressive in braking when cars changed lines in front of me. I use Q7 ACC pretty much all the time nowdays. I do accelerate and sometimes brake manually of course. However I enjoy the fact that I don't need to be 100% focused on driving when it is enabled. It is similar to how I operate autopilot in the plane: monitor it does the right thing but don't bother making constant minor adjustments. I am still mentally in the game, just for a different reason/goal.
