Many highways in Germany (autobahns) do not to have speed limit.
The Wikipedia says:
In 2015 70.4% of the autobahn network had only the advisory speed limit (130 km/h), 6.2% had temporary speed limits due to weather or traffic conditions, and 23.4% had permanent speed limits. Measurements from the German State of Brandemburg in 2006 showed average speeds of 142 km/h on a 6-lane section of autobahn in free-flowing conditions.
I would like to know not just the the legal maximum but also find some statistics about the real speed people drive on the Autobahn, but I haven't been able to get it. - distribution of measured speed of cars on the autobahn. - statistics of the number of accidents and deceased as a function of the speed.
I've just found very old data saying the average speed in 1992 was 120.4km/h and the 85th percentile 148.2km/h. And in 2006 in 6 lanes areas the average was 141.8km/h.
What percentage of cars exceed 200 km/h?
