I think it depends on population density as well. I grew up in a rural area in the US and now live in Philadelphia on a tiny side street barely two cars wide. Every single car on our street has scratches/small dents on the bumper and fender from others parallel parking. If you live here you have to accept that "bumpers are for bumping"!

I did not mean minor cosmetic things.

I mean broken lights, broken parking sensors, broken washer jets, damaged number plates etc. Modern bumpers are designed to prevent injuries to pedestrians - it may "look fine" from the outside but internal mounting brackets etc may be bent out of alignment or otherwise damaged. These are all expensive to put right.
