This extraordinary video shows a tractor moving along a street unattended after its driver forgot to turn off the engine and left.

Surveillance camera footage captured in Langfang, in Hebei, China, shows the man stopping the vehicle in the middle of the road on March 20.

He can then be seen climbing down from the driver's seat and taking one last glance at the tractor before moving towards the building.

However, just moments after he walked away, the unmanned vehicle can be seen rolling down the roadway and climbing onto the pavement before completely disappearing after making a turn to the left on its own.

Upon returning to the street, the driver was puzzled by the vehicle's disappearance. It reportedly took him a while before he found the tractor down the road.
