That's fantastic! I was thinking that NYC would be a perfect city to try separating the bike/car traffic (cars on specified main arteries with protected bike lanes, with trucks allowed to make deliveries on smaller streets during business hours, otherwise all other streets are for cyclists only), but our winters are so brutal, it wouldn't make sense to shut down so much of the city to traffic year round.
I wish they would just push through the legislation that would tax the hell out of traffic coming into the city, but there is too much pressure from the rest of NY state (not to mention NJ and Conn) to not do this.
