Hang on, no Snitches get stitches comments? That seems to be the ovveriding theme on these forums!
Nice one though OP. If I ever witcness any accidents etc, I always stop and give them my details. Despite the fact that the only time I had an accident (Other driver went through red light straight across a dual carriageway and I hit him square in the side) no one bothered to stop, despite the car being in pieces in one lane of the road.
