The Autobahn doesn't have many rules, but you are expected to maintain some sort of order while driving on it. It's a German highway after all. Their idea of humor is studying an Ikea manual and mocking its lack of organization.
This video predictably ends horrifically, with the out-of-control Audi driver ramming into a minivan, flipping the larger vehicle. The driver then bails out of the car on the side of the road, where he is apprehended by police. The driver was sentenced to three years and nine months in jail.
No word on the condition of the people or person in the van. Hopefully they were not hurt.
