Had a student go over my hood when I was in college delivering pizzas! It was dusk/dark and he was riding on the sidewalk on a busy intersection. Came flying out of nowhere when I was taking a left turn. He nor his bike was damaged, my fender had a tiny dent. He apologized profusely as he had no lights of any sort. It was the law at the time to have them. I believe he would have been issued a ticket. Then again, with me in a Domino's outfit I doubt the police would have viewed the situation in my favor. Either way, no harm no foul. I gave him $10 and told him to get a light.
