One street in a city the size of NY?
I thought you were joking when I read that reply. I thought it might have been straight out of a Monty Python sketch. ;)
On that note, if you want to get an idea what pedestrianization does to cities, enter "Barcelona Superblocks" into your fav. search engine.
GP's premise was there "Are none" -- I shared the progress I'm aware of.
NYC needs more, but I think the tide is turning the right way.
