Par for the course on the Autobahn. Trucks are forbidden from the left lane where there are 3 lanes, and even the slow cars do over 100mph.
I hit 270kph or 168mph almost every day on my short commute to work on A81. Perfectly safe if you pay attention and look far enough ahead and envision what the people to the right might do.
Here's a top speed run between 2 exits on the autobahn. Nothing to it.
