I knocked someone over, quite a few years ago now. It was late at night, I was on way home after a gig. Travelling through the local shopping area, pubs closing, chip shops and curry houses busy. A guy appeared in front of me from behind a van or something. I had no chance of stopping. I was probably doing about 30 mph, it was a 30 mph zone. He went up on to my bonnet and his head smashed the screen.
He picked himself up and apologised. His take away curry was all over the bonnet and screen. He said he was OK, but I insisted on him going to hospital. He refused. I said I would take him. He agreed only if I allowed him to drive his car home first.
We had to push start his car, I followed him, then took him to the local casualty dept.
I was due an early start the next morning, with a long drive. Fortunately I had screen cover on my insurance which included emergency replacement.
After finding out the process, where the nearest 24 hour screen replacement was, and arriving, the guy refused to work on my car - the take away curry was still all over the screen and bonnet, with a head sized hole in the screen. It was only after I assured him that it was curry that he agreed to work on it.
A few weels later I received an invoice for the ambulance for taking the guy to hospital. I phoned the hospital and explained that there had been no ambulance, I had taken him to hospital. They said it did not matter it was a standard procedure and charge and I should send it to my insurance. I threw it in the bin and never heard anything more about it.
