So if you are parked in a car park and a car parks up next to you - the driver opens his/her door hitting your car and denting it - you would be happy if he/she just walks away ?
The initial question I was asking really is - does an insurer class the two examples as an ' incident ' say for example , when you are filling in a proposal form for insurance , and the question is asked - ' have you had any incidents .... '
If someone opens their car door into someone else's car, that's negligence.
If someone parks by a lampost, that's stupid on the part of the parker. A lampost is much more solid than another car door. One causes damage, the other doesn't.
I'd report the door incident if opening my door into someone else's caused damage.
