A 52 car pile-up on the German Autobahn left three people dead. As you can see from the picture above, officials had to spray paint numbers on top of all of the cars just to keep track of them. The Autobahn has no speed limit, but an advisory speed of 130 kilometers per hour (81mph.) Even though the highway has no speed limit, it does have strict rules about passing which helps prevent a lot of accidents from occurring. Watch some footage of the pile-up after the jump.
