"There are only six American downtown districts that are dense enough to support mass transit, which you need if you’re going to be carless: New York City (Midtown and Downtown), Chicago, Philadelphia, Boston and San Francisco.That’s it."
So, other downtowns don't _have_ mass transit? Funny. I could have sworn Seattle had mass transit. Maybe it only counts if it has rails under it? Then what about Portland, OR?
I'm just going to leave alone the whole idea that without cars or mass transit, you can't possibly survive anywhere. I mean, what? Walk?!? Like, live close enough to the places you go to _walk_? Inconceivable? And don't get me started on human-powered vehicles.
