<prompt> Human: Im hoping someone has some insight into our situation and can provide advice for the best possible outcome.Last night in Denver we had some incredible hail for about 30 minutes. My wife currently has a rental car, as her vehicle is being repaired from an accident two months ago in which she was rear-ended.As the hail started, my wife ran outside to move the rental car from the street to the driveway in hopes of better protecting it from hail we have a large tree that overhangs the driveway.After she got into the vehicle, some random guy driving down the street pulled closely behind her in the gutter to wait out the storm, I presume, completely blocking our driveway. My wife did not see him do this through the rain and hail, backed up, and hit his car. The rental car bumper is damaged as is the hood of the other partys car.We have already informed the rental car company and will be speaking with our insurance today. We will be returning the rental car tonight.What should we expect from a liability standpoint? What will this cost us? Is there anything we can do to help our case? Yes, my wife did back into his vehicle, but who pulls directly behind a running vehicle and blocks someones driveway?!We were apologetic to the man as we all stood on our porch waiting for the storm to pass and he never said sorry in any way. The more I think about it, the more pissed I get. Im at the point where Im angry to pay anything. In my mind, he caused all of this by making a stupid decision.What do you think? How can we best resolve this?  <response>: Its a public street and she should have looked behind her. Blaming him is silly. She simply wasnt paying attention.
