I used to be very very precious about my vehicles and would have been up in arms if someone had dinged another car.
I've had 2 very powerful and (relatively) expensive cars. I've had the wing ripped off on one from someone (probably) driving a towbar on a truck into it and driving off. I got dings on the other. On another car I had every single panel on the nearside replaced by a cereless car parker who only owned up because another person had seen her.
However I've changed a bit from that position now. In an ideal world people would own up to it, but we don't live in an ideal world. Car park spaces are too tight, people do things accidentally, peple have kids/old people in cars, people are in a rush.
Naturally many would feel a little hesitant about owning up due to the relatively expensive cost of what will generally be a bit of thoughtleness.
We all know this happens so when you buy a relatively expensive car in some form you accept the risk that going about your daily business stuff like this can happen. You can't control the risk of it happening (you can mitigate it) so don't get concerned about something you can't control.
I CBA these days and just drive around in a car I DGAF about if it gets scratched/dinged (which it has in 9 months of ownership). It's inevitable.
