My car stays in my garage 80% of the week, I only use it when visiting other cities on the weekends. I chose a relatively dense Brazilian city and I do everything here by bike or on foot (about 6-8mi per day). People have started noticing that I'm looking healthier, fitter. It'd be very very hard to do the same in any American city other than New York, you people are trapped.
While it’s by no means the norm in most of the US, you can definitely live that way in other American cities besides New York. Chicago, DC, San Francisco all come to mind.
I drove and walked all over SF a few months ago, and while I agree it’s feasible, the lack of bike lanes is disheartening, much worse dedicated ones. Your standards are so much lower, it looks like your tax money goes into a blackhole never to be seen again, and I’m saying that from a very corrupt third-world country.
I would say that you'd be hard pressed to find a city of any moderate size where it was not possible. Some would be better than others, but it's possible nearly everywhere.
