Ya I'm living in Hollywood right now w/o a car by choice. It's totally functional for me since I live next to a subway stop and my work is also off a major stop. And the neighborhood is incredibly walkable--everything I need or want. Taxis readliy available should I need one.
Although being a single guy here, I think women see it as a red flag (at least from what I see on okcupid). Interested in moving to NYC unless I find somewhere cheaper and still interesting.
