Germany

The Autobahn is the federal controlled-access highway system in Germany. It is widely known for having no federally mandated speed limit for many classes of vehicles. However, speed limits are posted in areas that are urbanised, substandard, accident-prone, or under construction. A study in 2006 showed average speeds of 88 mph on a 6-lane section of the autobahn in free-flowing conditions. Oddly, the largest wreck in the history of the autobahn was a 259-car pileup in 2009, which, although it looked like the car crash scene from The Blues Brothers, did not result in any fatalities–just dozens of injuries.
