Also curious where you're from that you never heard of this.
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.
A simple example of what I mean is traffic lights. I've lived in many European countries, including Germany, and travelled a very fair bit in the rest. In Germany, traffic lights are green for cars for a long time and green for pedestrians a very short time (feel free to measure this at any traffic light in your city). In countries where infrastructure is planned around humans, it's the other way around.
Cycling is another example of this. Germany doesn't have "bad weather for cycling". People cycle to work in winter in Helsinki and don't bat an eye. The difference is infrastructure. Helsinki has not only built the roads, lights and the rest around it, but they also ensure it's in good condition. When it snows, bike paths often get cleaned before car roads. It's a matter of choice. I bring up Helsinki because it's easier to compare. Netherlands and the like are so far ahead everyone else in humane cities that the comparisons are hard to make. Helsinki is a good example because their developments are recent and go to show that you can choose to live a different way.
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.
