I think if you saw an autopilot fly an airplane that might change your mind. I got a front-seat ride on a twin-engine
Beech Baron (a VERY nice airplane, and expensive even by airplane standards) that had an autopilot slaved to a GPS navigational system. The day was very windy with a lot of turbulence that would bounce even that Baron around quite a bit.
This was flying in PA, over a rather mountainous region, and for fun we were clearing some mountaintops by maybe 100 feet. (Yeah, pilots often have a strange sense of what is fun.)
The autopilot made that thing fly like it was on rails, making course and altitude corrections in a fraction of the time that any human could possibly have done. It made a believer out of me. I realize that driving a car is much more difficult than flying an airplane because the environment is much more complex and quickly variable.
I'd be open to having a self-driving car. Especially if that was the only option to getting around.
