I've only owned one car, a German-made left-hand-drive Ford Capri, black with a white roof and all wood and red leather interior. It was a thing of beauty and I got it cheap because it was left-hand-drive and we drive on the left here. I gave up driving after about 4 years as I was useless at it. Not dangerous but certainly annoying to other motorists.
One car? I had double that in my first year of driving at the age of 16/17. Both were piles of junk though. I can't imagine not driving to be honest, but I know many don't. I guess it depends on where one lives and their job and so on.
