In PA, you only have to have the keys in the ignition lock, that is constituted as intent to drive.
Two guys came out of a bar at closing time, neither one is fit to drive, and they realize that. It was winter time and they were intermittently starting the car in the parking lot to keep warm, while sleeping it off. Cop sees a lone car in the lot, and investigates. The car was not running, but the keys were still in the ignition. He cites the guy sitting in the front seat for DUI because the keys show intent to drive.
A guy I used to work with has a brother that is a state cop, so I asked him about that, he says that it is correct, and it probably would stick in court. It sounded far fetched to me, so that is the reason I asked my buddy's brother. So in PA you can be on private property, not actually operating the car, and still get pinched if the key is in the ignition, it doesn't seem right, but he said it was......
