Consider what universal adoption of autonomous cars would suggest about the role of the individual versus the collective - what the sociological implications are to that degree of control being imposed on the way people physically move, and the way they make decisions about where they go. The whole premise that people can't be trusted to manage their own autonomy beyond walking distance without being mollycoddled by an AI (and by extension, inevitably, the state) is just creepy.

Unless these advancements are specifically designed to put full control in the hands of the owner of the vehicle and no outside intervention possible then your fears will most certainly come true.
