There is a bowling alley right across from me. The bowling ally is on a one way street, so a lot of people go through the ally to get around the one way street. I believe that this is happening after league bowling lets out. I would bet that there is alcohol involved. They are probably looking at their car the next day and insisting that someone sideswiped them in the parking lot. It would also explain why no one has ever stopped to say they damaged my property, they would get an OWI/DUI to go along with the damages.
