http://www.sehinc.com/news/truth-about-speed-limits-explaine... There is no guarantee that a speed limit will have any effect on driving behaviors. The fact is, when driving, most motorists choose a speed in which they personally feel both comfortable and safe.
https://en.m.wikipedia.org/wiki/Autobahn#Travel_speeds on a free-flowing section in 1992, the recorded average speed was 132 km/h (82 mph) with 51% of drivers exceeding the recommended speed. The autobahn has a long history proving that people feel comfortable and safe at excessive velocities.
So it seems that 130 km/h (81 mph) is not all that excessive.
