Watching German politics more closely during those years, I have seen that choices between: is better for car owners, is better for something else, gets decided in favor of is better for car owners 90% of the times. Heck, even some members of the Green Party are very cozy with the car industry (e.g. Kretschmann).
It is a bit unusual outside of the Netherlands and Denmark.
I tried to cycle to work 8km or so and it was fine until I had to cross a slope. And since this slope was etched by the nearby river, it went through the whole city, so there wasn't any way around it.
Took all the fun out of it honestly, especially during heatwaves.
The Germans probably don't know that with 2cm of snow, all the other means of transport, including the Amsterdam metro, stop working. So bicycle it is. I loved my 25km (round trip) bike commute when I lived there, it was such a great way to clear my head before/after work.
