This is when you need a flesh-eating lawyer.
I don't know what I'd do if I ever found Diana like that. I know that I'd lose it, especially if it was a drive-away. That's one of the reasons I never park in parking spaces in shopping center lots. I find a nice place out of the way off to the side where no idiots ever drive. At the local Lowe's, there's a little courtyard with a big planter in the middle of it. I park behind that planter, about 20 feet from the contractor's entrance. All the Lowe's employees that have ever seen me park there have said it was a good idea to be there and was okay, since no one ever goes behind that planter.
Man, I really hope you find the driver, and get the book thrown at him or her. Hitting the bike, damaging someone else's property, hit and run, leaving the scene of an accident, and anything else you can think of.
