I was in a situation very similar to this, the difference was that a child on a bike ran into my car. The kid was fine, but was wailing and bawling. My friend and I got out to check on him and people started coming out of the apartment buildings. I looked up and it was like a swarm was descending on us.
Luckily, the police arrived very quickly and sent everyone home. The child admitted that he wasnt even looking where he was riding and hit my car. His parents (I think aunt and uncle, but not sure) said he does this all the time and wasnt even supposed to be out at that time of day.
I ended up getting off lightly, but before the police arrived I was truly scared for my life.
Geeze, you do the right thing and look what happens. Has it come to the point where a driver has to take his chances with a hit and run charge instead of taking a chance with his life?
