91. Rules of the Autobahn, no passing on the right!
Just try to remember that one
I know I couldn't get used to it, and it confused the heck out of me, so if you drive on the left lane you must go super fast otherwise it's impeding on the traffic, so drive on the right slow lane with the trucks. But if you want to pass the car in front you, make sure you highbeam him and get on his tail, because you cannot move to the right lane and pass him, got it??!
