Its weird it wasnt in park. Dudes lucky somebody came along otherwise hed have crashed into something eventually. Going at 2 MPH he coudln't cause that much damage. You think his car tops out at 2 mph? In that case, I don't know what we're all worried about. Considering he was sleeping, I think he's assuming (rightly or wrongly), that at that point, all he'd be doing is idling forward.
