My father didn't like cars, apart from occasional (possibly midlife crisis type) fantasies. For many years, he did his daily commuting by bus, bike, or foot (depending on the era). He started when he was finishing a degree because the parking situation was so bad. Bus meant no parking problems, no second car to maintain, etc. But the last 20-some years of his working life, a car was the only viable choice, although (before he got married the last time), he did talk about moving close enough to his office that he could easily walk every day.
I'm currently using bus service on a day-to-day basis, but the schedule is pretty limiting at times. One thing that gets me is that there is all the talk about how more poeple should ride the bus, but there is apparently no real understanding that a reason people don't ride is because of service limits. And, of course, the agencies--which try to sell people on using the bus--will say "we can't improve service, because we don't have the ridership."
Past limited service, my area at least has no real problems on the bus. But I hear horror stories about what happens on some routes. Drug use on the bus. Shootings at bus stops. It's understandable that a lot of people who'd have to take those probelmatic routes might decide they'd prefer owning and using a car.
