My father has a similar story. Stop light, dad wants to turn right. There is a car ahead that isn't turning, and no space between the car and curb for a motorcycle to squeeze through. A car in the left lane decides he is going to turn right, and that he can somehow squeeze through where my father's motorcycle couldn't. He turns his head and, looking straight at my father, turned into his lane, pushing dad's bike against the curb, bending the wheel, though fortunately not injuring him. Then the driver, having just wrecked a motorcycle, is stuck behind the same car my father was waiting behind. My father says he walked around to the driver's door and the driver kept his head locked straight ahead, refused to acknowledge anything, refused to get out of the car.
If you get into a similar situation, remember not to do what my father did, which was to spend the rest of the time until the light changed kicking the car with his riding boots.

When the light changed, the driver just rolled on as though nothing had happened.
There are some seriously maladjusted people walkin around.....
