There are relatively few cities (of which Manhattan is probably one) where, if I lived in the city, I wouldn't own a car but--yes--I might park somewhere on the periphery where it was cheaper and not use it day-to-day. I know very few people who aren't maybe just out of school who don't own cars even if they live in a city.

It is easier to get by with things like Zipcar and Uber but I'd still probably find it had value so I wasn't structuring things around not having a car.
