I was home-schooled, so I didn't have Drivers' Ed. I took some private lessons when I was a teenager. The instructor told me that I had to turn my head to look both ways at each intersection. When I later did so, he told me that I did NOT have to turn my head to look both ways at each intersection and that I should just look with my eyes. ??? He also said things like, "You gotta ask yourself, are you gonna DIE at this intersection? Or just your instructor?" When the lessons concluded, he told me I needed more road time. I never got around to it and I still don't drive to this day.
I grew up in a town where you could easily walk from one end to the other. Also, I didn't have the "normal" teenage inclinations to get away from my parents so I could party, pick up prospective romantic partners, etc., so I don't think I had the motivation.
Also, because I tended to daydream, my stepfather told me that I was likely to do so while driving and would wind up accidentally killing people. I usually got a lecture to this effect whenever I missed something he said because I wasn't paying attention.
I live in California, where it's generally assumed that everyone just sprouts a car when they turn 16. Over the years, I've gotten some funny looks when I say I don't drive. Maybe that's gotten a little less common since nowadays a lot of people can't afford a car. I take the bus to work and I've taken the train a few times to go to Disneyland.
