Car doing reverse donuts

There is something bizarre about watching a car going around in reverse circles on a city street, its open door crashing repeatedly with a post, with police and spectators looking on and doing nothing.

After awhile it gets monotonous but you can skip to the 6:45 mark to see how it ends.

When I first saw this I wondered: Is this for a film? A bet? The description says that this happened accidentally when the car started moving after the driver and passenger got out to switch positions.
