came here to say this, been riding in NYC since a little kid from brooklyn to manhattan and beyond.

I see people who can barely ride a bike try to lets say ride down Atlantic during rush our -- Atlantic ave all these years will still turn you into a white bicycle. I see people who ride like they are in a small cul de sac in their former suburbs assuming a car will stop for you , or can even see you over parked cars. I see people ride right into the tail of a tractor trailer or truck or long bus in thier blind spot as they are turning and they have no idea how trucks turning work - they are like - they should be aware of me and ride right into being crushed.

I see people skip lights (ps i skip lights but i look :) without looking because they think they did it 20 times on that street, the 21st no one will be barreling down to catch the yellow.

I weave in and out of traffic, i used to be a bicycle messenger. Its nothing wrong with it if you know what you are doing. If you came from the suburbs of NJ and just start weaving, yeah you probably gonna get crushed. I think the main thing is really sloppy intersection crossing without being aware, and the dynamics of turning vehicles and their blind spots. I see a vehicle wants to turn and they dont see me? I have no problem stopping and waiting for them to complete the turn -- even if I have the green light and right of way. Try telling the car is wrong when you are under it, when they barely can see , they forgot their glasses and decide to catch a parking spot that just opened in the middle of your right of way. keep your eyes open and watch the patterns!
