I've come to accept that people aren't going to stop for red lights (yellow means speed up), and I habitually check to make sure people have stopped before I enter the intersection when the light turns green.
Last night, I was stopped at a red light at an intersection of two three-lane roads. My light turned green, and when I checked the other road the cars were all stopped at the light, so I started going. As I was in the middle of the intersection, even with the car next to me (neither of us accelerated very quickly), a car flew through the red light and into the intersection.
He passed directly in front of my car, close enough that I could see that the driver was smirking directly at us. Based on the look, I actually think he might have seen us and calculated that he could get through the intersection in front of us.
