That's the decision of a police officer or a judge.
If you are driving the backing car, no matter WHERE the other cas is located, YOU are the one at fault if you collide with it.
The person backing out.
Any time the driver who is backing is at fault, in all 50 states.
The person at fault would be the one backing into a parking space. Because they are going to look at it as, your supposed to pull into the parking space front first, not backing in. So it would be your fault. But I'm sure that both of you would get a ticket or something else, because they hit you, and you are violating parking lot conduct.
Well if you were backing in and hit someone then it is your fault. But if they hit you, then it is their fault.
both of you for not looking back
both because ur not quick enough ;) the other guy is thick cos he drove into you!! So more his fault!!
The driver backing up. Unless you can prove the other car was driving unsafly.

The person backing out. If you were in the lane/road behind them they needed to use caution when backing out.
