I appreciate the story, and I can understand that mindset personally because I have also been dissuaded from driving by my knowledge of the danger of cars.
But it has never persuaded me to support tough car restrictions or bans on cars for other people. It's a personal risk calculation that I do not impose on others. I don't know the shy child you mention at the DMV, but I doubt he was persuaded to outlaw cars for other people either. That's a mindset I do not understand.
