If you're talking about livable within the city limits (i.e., you don't live in the suburbs) then I think you'd find locals in Boston, DC and Chicago would say they can live happily without a car. I think a pretty significant chunk of folks in Philly, Portland (OR) and Seattle would probably say the same, though not to the same extent as those other ones. Not disagreeing that there are few overall, but there are a few beyond NYC and SF.
