The fastest movement allowed for vehicles in a specified area or on certain streets or roads: Germans are all revved up over speed limits on German autobahns.

Half of the 12,000 kilometers of autobahns already have speed limits as do smaller roads; however, the "anything-goes" stretches of the autobahn are the fastest public roads in the world.

Germany has a significant economic incentive to resist a speed limit because it builds some of the world's fastest cars, and the autobahn is a valuable showcase and marketing tool for the industry.
