Car sex?
A good friend had a Triumph Spitfire which wasn't really any good for back seat sex. As a result he used to have sex with his girlfriend across the seats with the passenger door open. On one such adventure they were going at it so energetically on muddy ground that the car was shunted sideways into a slight dip. The passenger door slammed shut on his legs fracturing his shin. Mobile phones were uncommon in those days so he had to drive his girlfriend home then go to hospital.
