I have the same (possibly mistaken) impression of Germany as an outsider. The US is also remarkably contradictory in its supposed values. I think it would be interesting if there were a semi-objective measure of this quality.

Maybe that is the point. The contradiction about what you expect, and reality. Like in Italy is expected to go and find out this or that is messy. But Germany has a strong image of responsibility, seriousness, efficiency, etc. And when you see closer, is not.

Also, what I'm not sure, I'm trying to find out, if there was a change in the last 1 or 2 decades, or was always like that. Like now, except for things like you here a siren and cars open like Moises opened the water, in many other things, seems to be not more organized that any other country. Hell, sometimes compared with Bangladesh seems to be lagging behind (point example: birth certificates)
