What does the law say about sleeping in your car? A coworker's son went to a bar, got drunk, started to drive but realized that he was too drunk to drive, pulled over, threw his keys in the back seat and went to sleep. Some cops woke him up, arrested him for a DUI, and took him to the station. He's got a medical condition where he sometimes can't hold his bladder, pissed his pants, and got punched in the neck and kneed in the groin for it by the arresting sherriff.
