You know what happened regarding cats as rabbit hunters in Australia?

Cane toads, too: https://en.wikipedia.org/wiki/Cane_toads_in_Australia

* "should" vs. "must", you might find this useful. And also: "guidelines", not "rules".

"almost all" is correct, they are nearly universal. At least for residential windows, maybe not in offices.

Yep. Thanks

Automobile lobby? That's BS. The German rail system has been cost-saved to death, it now barely handles the increased passenger volume as a result of the D-Ticket. Overcrowded trains, even more delays and train cancellations (b/c of insufficient staff coverage, malfunctioning doors, etc.) even with S-Bahn trains are getting out of hand. "Transitwende" my ass! Same with the "Energiewende".

How i envy the Dutch and Belgian transport situation!

I don't get why you would write your first two sentences. It is very obvious how the automobile lobby has a direct influence here. Here is an excellent documentary (in German) that analyzes the issues with the DB. https://youtu.be/-dmtNToFwuI?si=3ydA_QOjzOvTke2_&t=480 At the linked time stamp, they mention that every minister of transport in the very influential period from 2009-2021 came from Bavaria, with heavy influence from companies like Audi, MAN, and BMW.

> The German rail system has been cost-saved to death

Yes, because the the traffic ministers allocate the spending of their resort to the Autobahn instead of the Deutsche Bahn.
