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.
