Footage, from China, of an unmanned electric tricycle crashing into five cars.

The video, filmed in Baoshan, Yunnan Province on April 8, shows an out-of-control, unmanned electric tricycle bumping into several cars waiting at a traffic light.

Then, it somehow turns around and comes back to collide with another car before it finally stops.

According to local reports, the tricycle driver hadn't taken the key out or put on the brakes before he climbed out, so the vehicle went on the rampage by itself.
