The Autobahn has become very tiring to drive on. Most people somehow decided that its easiest to drive in the middle lane at slow(ish) speeds, while the right lane stays empty for long stretches. Since you are not allowed to overtake on the right lane, both the left lane and the middle lane are clogged most of the time, averaging about 100-120 Km/h. If the public transportation was a bit more reliable and cheaper I would sell my car.
