Hah, with all due respect, 11 year of riding in urban areas prove you wrong. I've constantly got my head on a swivel, and do anything to stay away from cars as much as possible. I've gotten to the point where I feel safer on a bike than in a car.
Motorcycles respond 100 times better than cars to locked up brakes and such, because they're much more maneuverable. I can't tell you how many times someones locked up their brakes in front of me and I've been able to completely maneuver around them.
A bike is only as safe as the rider, and, in my case, I'd rather be on a bike than in a car any day.
