A moped rider who was violently thrown off his bike, losing his shoes and helmet in the impact, simply got up and run away.
Shrugging off help from a passerby, and not looking at the mangled wreck of the bike, he runs off into a field.
The crash happened close to Hampstead Heath in London in November, with footage only just coming to light.
The dashcam footage shows a silver car waiting to come out of a car park on to East Heath Road.
The car with the camera, which appears to be about to drive into the car park, waits patiently for the car to pull out.
