German here. Some of it I can agree with. The traffic light though is very simple. Yellow means “it was green and will turn red”. Red+yellow means “it was red and will turn green”.
It’s this way in the entire country. There are many things I can get upset with in Germany (I moved abroad 10y ago and have an outsider’s perspective by now) but the traffic light example to me just indicates you didn’t ask why certain things were the way they were.
After reading some parts of this thread, all I can recommend is the following: https://www.goodreads.com/quotes/539867-never-argue-with-an-...
(I'm sure there are various German things to criticize or to make fun of. Much of what I read here, however, says more about the (US?!) authors, though.)
It’s so German to blame the user!
"The traffic light though is very simple. Yellow means “it was green and will turn red”. Red+yellow means “it was red and will turn green”."
That was not the point, that's the standard way the lights will work.
The point is that sometimes you have a light combination where actual light post only has yellow/red for example (no green light). Sometimes you have a light post that has red only (on, off).
