the economist report some year ago, that NY was the only city in the America's to experience "pedestrian traffic jams"

A certain amount of foot traffic is required to have effect.. it is (according to the Economist) quite common in old world cities, like hong kong, or bombay, but not general found in new world cities, since it takes a large populations and a certain attitude..

i think it is one of the pleasant endearing charms of "small towns" like chicago or LA that they do yield to pedestrians. i have also heard, that LA cops will ask for ID, and give NY'ers a warning for jaywalking... but natives they actually fine!

Jaywalking is very rare in Japan, and my sisters kids have learned two languages, and two sets of rules.. at home you speak japanese, and when in NY, you can sometimes jaywalk.
