A couple having sex flipped their car when they released the brake in error.
The lovers, believed to be students, were romping in their Toyota Yaris when the incident happened and were stranded for 15 minutes until they received help from passersby.
The car tumbled down an embankment before it ending up on its side in a dark country lane.
The 18-year-old driver was in his boxers as he scrambled to find his clothes, while his red-faced partner left the vehicle via the boot.
A friend told The Sun newspaper: "It was like a scene from 'The Inbetweeners'. We were meant to be meeting him that night but he took this girl up to Wirksworth in Derbyshire. It's very romantic up there.
"He put on some music and they started having sex. Suddenly the girl's yelled, 'The car's moving'.
"He was concentrating that much he didn't notice the handbrake."
