Who is at fault when someone opens their car door and hits your car while pulling into a parking space?
It's called, "Undue care and attention" and both of you are at
fault. The person didn't look to see if there was a car coming, and
you didn't look to see if someone was going to open up their door.
This is a "Mexican Stand-off" and it's best to come to some
conclusion over this with the other person if possible ... you each
share half the cost of having your vehicle being repaired. Good
