Just set any car on fire and if you don't secure it, the car might just take on a life of it's own. Sometimes even controlled situations get out of hand.

This firefighting demonstration in Somerset, UK gets to rolling on its own and luckily still gets put out. Setting a car on fire, that still has the battery attached and is not properly wheel chucked, might just take on a life of it's own.

All we need is the Benny Hill Theme playing in the background while these firefighters run around trying to stop it. I hear they finally got the blaze they started under control.
