Today, while riding, my bike threw up a rock that hit the car next to me in the door. It was a brand new car and may have caused a chip or small dent. The owner looked angrily at me and kept going. If they had pulled over and damage was caused, who's fault is it, from a legal standpoint? I guess it would be like a rock getting thrown up by another cars wheel and breaking your windshield. I think in that circumstance, the problem lies with the vehicle with the broken windshield. What do you think?
