I friend of a friend told me they were parked on a street outside a friends house after a wedding. Came back to the van after few pints and went to sleep. Apparently they were reported to the police for drink driving. About 3am they were woken by a knock on the door. When they opened the door they were confronted by a young police officer who was adamant that were in charge of a vehicle whilst over the limit and wanted to breathalyse him. But he had left the keys to the van in his friends house in his jacket and a senior police officer pointed out how to the young officer, how can he be in charge of the vehicle if he has no keys to drive it. So if you have not got the keys inside the vehicle you are not in charge of it. (apparently)
Its a second hand story but I think it sounds plausible.
