Smrobs, I had something similar happen to me. Had the ball on the back of my truck, and some moron wasn't paying attention and slammed into it. Buckled the whole front of her car, and my truck had no damage whatsoever.
She was shrieking about her car, I was going to get sued, blah de blah blah, when I reminded her that SHE hit ME and I'd be more than willing to wait for the cops to show up and make a report. That shut her down pretty quickly.
The strange part is that it was during morning rush hour, and I was stopped at a red light when she hit me.
