That's not why most people drive cars. I've lived in cities with public transport all my life. But when I got my driving license, my life quality increased enormously. It's like night and day. Not only can I drive where I want when I want, I can avoid other commuters that are very often loud or annoying. I don't have to stand at bus stops or train stations and seeing them being delayed or canceled either.
I agree that some people drive poorly though. But the solution is to train them better, not to get rid of cars. You can hardly have an adult life with family without a car.
