A Chinese couple had a lucky escape when a driver hit the accelerator instead of the brake and nearly shot off a 50ft rooftop carpark.
A security guard at the car park, in Changsha, capital of Hunan Province, said the couple worked for a company nearby.
They arrived for work, as usual, one morning but while manoeuvring into a space, their black Chevrolet suddenly started shooting backwards.
The car smashed through a perimeter wall before coming to a halt teetering dangerously over the edge of the building.
The guard added: "They both looked terrified as they crawled out of the vehicle. It looked like it could have crashed to earth at any moment."
They escaped unhurt - but an unfortunate deliveryman needed hospital treatment after part of the stone wall landed on his feet.
