>whenever I drive on the german Autobahn at some point it happens to me that I'm in the left lane to take someone over and another car comes speeding towards me from seemingly kilometers away at the speed of a damn rocketship

It sounds like you're doing something wrong if this happens regularly. Either you're overtaking without paying attention to your surroundings or you're overtaking cars your vehicle isn't reasonably capable of overtaking.

Going slow on the fast lane is supposed to be uncomfortable.
