It's crazy how in a city of New York's caliber, with great public transport, so much space is taken up by cars for so little gain. The total lack of "walking streets" (streets entirely for pedestrian use for Americans unfamiliar with the concept!) is baffling to me. I think it would be perfectly fine to for example close something like Broadway or even 5th Avenue to cars, the businesses on these streets derive almost no traffic since it's all pass-through. Can you imagine how much better that would be for almost everyone, businesses included, what a destination that would create with a whole avenue packed with people? Close of the streets around squares, instead of creating islands in the middle of traffic you'd get street cafes. Just one, pretty please?
