query: What's the speed limit on the autobahn?
passage: Speed limits in Germany
General speed limits in Germany are set by the federal government. All limits are multiples of 5km/h. There are two default speed limits: 50km/h (31mph) inside built-up areas and 100km/h (62mph) outside built-up areas. While parts of the autobahns and many other freeway-style highways have posted limits up to 130km/h (81mph) based on accident experience, congestion and other factors, many rural sections have no general speed limit. The German Highway Code (Straßenverkehrsordnung) section on speed begins with the requirement [1] which may be rendered in English:
passage: Autobahn
Germany's autobahns are famous for being among the few public roads in the world without blanket speed limits for cars and motorcycles. As such, they are important German cultural identifiers, "... often mentioned in hushed, reverential tones by motoring enthusiasts and looked at with a mix of awe and terror by outsiders."[1] Some speed limits are implemented on different autobahns.[25]
