I see how this statement makes sense for some, but many people in Germany, especially in big cities, drive a car only a handful of times a year, if they even have a license.
There are many cars and many car owners and many car drivers in Germany, I think the stat is something like >3/4s Germans own cars. There happens to be public transport and bicycle infrastructure proportionate to the density of a region (ie more in cities), but lots of Germany is still rural, sparsely populated, and dominated by cars for getting around. If you aren't from/in Germany and visit it, you'll see how popular cars are here and that is unlikely to change soon.
Didn't assume it's rare, just if it's the majority. But yeah your numbers clearly point to a majority being drivers. I guess even most public transport users do have a car then for occasional use.
