While on paper the allowed speed is 80 km/h, in fact it is 89 which is the hard-wired technical max speed of most trucks. Additionally, driving 89 is not prosecuted. In a capitalist world, a trucking company whose trucks sticked to 80 km/h would vanish very soon. Therefore 89 km/h is the standard speed. If a driver decides to go slower than that, trucks will try to pass them, period. Additionally, there is the "Richtgeschwindigkeit" for cars of 130 km/h in Germany as you may be aware of. That being said, I do not endorse tailgating or speeding in any way. I just wanted to add another perspective.
