On august 6th 1932 Konrad Adenauer opened the first German Autobahn. The revolution in transportation made the term Autobahn known all over the world. At the opening only few vehicles could reach the top speed of 120 km/h. Today the German motorways are famous for the lack of speed limit. But motorways are very special in every country. Wide and crowded in the USA or new, long and also crowded in China, which since 2011 has the most motorways in the world.
