My best friend once rear ended a school bus one morning at the intersection by our school. TO make it worse, it was the bus we would have been riding if we had not driven. Didn't do any damage, barely hit it, but there was contact. He just didn't completely stop in time.
This same guy did the same thing to the front of a little convenience store too.
And, he helped me learn to drive.
Don't worry, the student surpassed the teacher.
