Honestly germans seem to love to dunk on their own infrastructure. Pedestrian, bicycle and public transport infrastructure truly is on another level compared to the US. Why this is the case? I believe its because cities where already in place when the car was invented. In the US they were built for the car as a mode of transport when European cities where built in a way that was a lot more pedestrian friendly.

While the punctuality of DB (German railway operator is a mess) local regional trains can be pretty consistent and overall cities have a well built out priority, since we had to accommodate for so many peoples transport withoutbeingg able to built them as car friendly since the urban centers where already built. while the funding somewhat lacks today, this made public transport also an important thing people look out for.

Bicycle infrastructure can also be hit or miss depending in the region, but generally it is also on the radar of planners and there's plenty of routes, although they're nothing like the Netherlands.

Germans also really like shitting on their own country and being really critical which comes with its own upsides and downsides. For rural areas the car is definitely really important for getting around tho
