German freeway-system without upper speed limit, but since 1974 an advised speed of 130 km/h. The length of the Autobahnsystem in 1996 11,080 km. There have been 26,627 traffic-accidents in 1999.
This is right, there is no fixed upper speed limit, (having thousands of local ones) for cars, but there is in fact a lower speed limit. No vehicles slower than 60 km/h are allowed to drive on the Autobahn. Large lorries have a speed limit of 80 km/h.
Most of the time there is no advantage of having no speed-limit except in the night as most of the Autobahnen are full and there really is no fun driving then. At night and in a fast car you can have a very fast and pleasant ride. And there is always someone driving faster than you.
