I'm not sure with your area, but that isn't the case here. What if it is a private claim? So lets say John backed his car into his own garage. I doubt he is going to claim insurance, so he brings it over to his buddy Steve who owns a shop. He pays cash and everything is fixed. Everything is off the record.
Not sure how it works elsewhere, but over here, by law, any damage over 2k has to be reported. (Although a lot of people don't)
