I hit my brother once in 1969. Accidently popped the clutch in the driveway and ran him down. Then I got off the bike (it was his) and ran like hell. When it was all over the bike was in much better shape than I was.
My wife ran over her MSF instructor in just about the same way. She went to stop and thought she had it in nuetral. When she took off right at him, he jumped up and straddled the front forks. But she didn't dump the bike! I don't know who was more surprised. When it was over she asked the teacher if that meant she failed the class.
