As all Geoguessr players know, official Street View coverage in Germany was extremely limited and all very old. There was a small amount of coverage in around a dozen or so of the largest cities that dated back to the mid-2000s and that's about it. There's also various bits of crowdsourced unofficial coverage in the country which you are perhaps referring to, but it's very limited. Just go to Google Maps, look at Europe, and grab the Street View person, and you'll see.
