Quoted from pinzrfun:

My son's car got hit in the middle of the night in front of our house. We live in the back of a subdivision, only traffic is neighbors. You could clearly see where the cars fender had dragged down the middle of the street, around the corner and up into a driveway/garage. Went to police station, they wouldn't even knock on the door so I did. They insisted the young daughter, my suspect, hadn't been in an accident but refused to open the garage. Mom said "Let me go ask her", walked around a corner for literally 5 seconds, came back and said No, her car is fine.
That was 2 years ago - the scrape in the road and their driveway has now rusted/oxidized, and you can still see it plain as day.
Don't expect ANY help from the cops.
