Not sure how and why, but a driverless tractor appeared out of nowhere in a Walmart parking lot in Richmond Hill, Ontario, scaring the bejesus out of citizens! As you see in this video filmed  by passer-bys, the tractor circles around itself in the parking lot and crashes into a couple of cars while the Police is just watching incapable of doing anything. The Tractor eventually hits a wall and somebody manages to shut it down. Still, this is a very rare event! The person responsible for this is in some deep trouble.
