There is no message here. I've lived in NYC. If you mouth off to someone - whether they are cyclist, a pedestrian, or flying a zeppelin - you can expect a response. NYC is a dangerous city - despite the mayoral campaigns to boost the image of the place to draw in more visitors - and you don't do that!
The fact the person had a bicycle is about as indicative of cause/result as wearing shoes. He might as well be riding a broomstick, and the other one having springs on his feet.
I smell TROLL here. Pathetic. Please don't turn this turkey into a 20-pager.
