It's like a scene you'd see in a slapstick movie, except this one's all too real.

A Mercedes, fully engulfed in flames, sat in the road in Notodden, Norway, a few years back. Firefighters soon came to extinguish the fire, but as they were trying, the car began to roll forward -- possibly from the force of the water, possibly due to a melted emergency-brake wire -- and then straight down a long hill, smoke billowing upward and back the whole way. Fortunately it didn't hit anyone or destroy any property, but wow, that's not the sort of thing you see every day.
