Drunken (or well oiled) driver
I used to live on the Suffolk coast and, occasionally after an evening shift, I would pop into the local pub for a quick pint and chat before making my way home.
One of the local pig farmers would be there and, well oiled, would stagger out at closing time, cross the road, get into his car on farmland and drive home across private land.
The local Bill, quite rightly, decided to have a purge on drink driving. (as well as after hours drinking as this was a pub all on its own in the country).
They would regularly sit in their panda car near the pub to get the drunks and the late night opening stopped too.
One night the farmer crossed the road as usual, and as the police watched, climbed into his car, gave them a wave and drove off, honking his horn with the morse code "V" - di di di da repeated. :p We all cheered and clapped.
But the Police had the last laugh. Some days later they parked on an unmade up road called Sandy Lane. When the farmer crossed this gravel road as he went from one field to the other, they stopped him. He protested that he was on private farmland. But they pointed out that for a few yards he had actually been on a public highway and the law applied - and it did - and he lost his licence.
