You mean competitive sports cycling. Everyday commute or leisure cycling is awesome in Germany. (Well, I often get aggressively almost run over by ruthless sports cyclists who treat every way as their highspeed training center every now and then...)
Good point. I know many fellows, who forget that they are moving way faster than expected and it's the competitive cyclist to blame. Oddly enough, I know a few groups who basically race in the traffic; However, the ones I know, reside in Netherlands. Most of the time, when I see conflicts between cyclists and cyclists or pedestrians it is due to bad design (of the pathways of each of one).
In Germany often simply a few red stones in the sideway are defined as cycling path. Recently, cyclist traffic gets detached from the sideway and placed on the road. What is good and basically copied over from Netherlands and Belgium. A downer at this point is, that the state doesn't change the width of already existing roads, though it would be possible sometimes. Thus cars constantly are driving on this "cycling lane" or simply forget it is there.
Basically, I'm speaking of (road)cycling and cyclo-cross. Not necessarily competitive. Considering commuting it gets better, as nature and sustainability is more in political focus these days. However, it is _really_ far away from the infrastructure you see in Netherlands and Belgium.
But it is also depending upon what you compare here. So, considering a global view, I guess that Germany is way over the top. Considering good design, Netherlands and Belgium have my wholehearted appreciation. Netherlands even much more than Belgium.
On a side-note: I do not believe Strava neither has much commuter nor too much "leisure" data, imho, most of them are somewhat ambitious.
