The police will do the square root of fuck all.
I once had a drunk on a motorbike hit my car - took off the wing mirror and dented the front driver side panel. When I called the police about the shitfaced motorbike ride who wanted to "nip home to get his insurance papers" (he wasn't insured), they had zero interest in coming out to nail a drunk driver that had nailed my car. Fortunately - I kept him there while the insurance guy came and the poor drunken bastard had to pay $200 on the spot and sign a direct debit form for the rest of the payments - I think they are used to the police not bothering.
