Maybe its more of a statement of how long I've been commuting, but all of the videos posted so far are daily occurrences. My worst was being hit hit by a car: driver ran a red light, and admitted that he never even saw it (I assume he was texting or something). Right in front of a police station! Thankfully, I walked away with a "few" bruises but nothing broken or seriously injured. So my expectations are pretty low...
I run a few consistent routes where I've learned the typical dangers and traffic patterns. I've had drivers at crossroads look in my direction, but then just take off and cut off my path. At particular stoplights, the red lights are routinely run. Some stop signs are never obeyed. Some lights I routinely see right turns on red without looking or stopping. And other intersections, there are frequently car-car near-misses, so I hang back to avoid getting caught in the debris from a car-car accident. Pedestrian crosswalks - good luck! I always wait for both directions to stop. So much for the NJ law requiring cars to stop.
I always try to take a conservative path. Never jump the green. Avoid blazing through yellows. Usually, I stop 2-3 cars behind the line and let the cars go first, but at specific lights I head to the front to get a good view. At all crossroads, 2-way or 4-way stop, if I can't see the whites of the driver's eyes looking at me, I come to a full stop even if I don't have a stop sign. In some areas I try to mingle with the cars to avoid getting doored or backed into. I pay particular attention to when I leave relative to sunrise or sunset. Some intersections I avoid during times with bad sun glare, which may require that I adjust my departure time by 10-15 minutes or changing my route for a few weeks.
Commuting takes full concentration. I relax on my 6am Saturday morning rides.
Finally, I never yell at drivers (well, almost never

). If I yelled at every driver that did something dumb, I'd wear myself out.
