Left: some guy in a X5 driving steady 150km/h, not reacting to getting flashed and immediately accelerating if you try to pass on the right.
Somehow, as soon as you get out of Germany this stops happening. In France and Benelux you get to comfortably cruise at 250km/h and everyone just moves out of the way.
German autobahns are not exhausting because of the lack of speed limits, they're exhausting because of the Germans.
