Rephrasing it: I don't want to be the one preventing the car from doing stupid things. I want the car to be preventing me from doing stupid things.
For example my wife's previous Toyota would gently shake the steering wheel if I were to switch lanes without using the blinker. Or it'd warn me if I were to put my blinker while a car was in the lane I was planning to go to. Or take start and stop trafic, bumper to bumper in trafic jams... I want the car to prevent me from bumping in the car in front of me if I'm not careful enough (the Toyota didn't do that).
Stuff like that.
I find it very stressful to have an "autonomous but not really" car that I must baby-sit. I want instead to feel more relaxed by knowing that the car is probably there to help me should something be about to go wrong.
