If you have traveled so much in Germany, you may have also met the most famous and widespread street “Einbahnstraße” many times, and probably many times in the same city.
I lived on a couple of one way streets in West Germany. One was horse shoe shaped (it connected twice to the same main road) and was wide enough for two way traffic. Thinking back, there was no discernible reason for EBS. Traffic was minimal.
It took me a while to learn how to pronounce it. It's not really harder than "industrial estate" but it looked very exotic to me back then.
I should also note that "Ausfahrt" is the largest town/city in Germany - its everywhere according to the autobahn signs!
