With some exceptions (especially in places where car ownership is a real financial/hassle burden like Manhattan), my observation is that people who choose not to own a car even in an urban environment with good public transit end up making a lot of lifestyle compromises. Even leaving aside trips to the emergency room, sick pets, etc., they just don't head to the mountains/beach/etc. because it's too big of a hassle. And especially once you get past a certain age, you can't rely on friends with cars like we did undergrad. Perfectly valid choice but, for the most part, you just don't do things that are a pain to do.
