The vast majority of Germans don't drive on the Autobahn at such insane speeds, and this certainly isn't an option anywhere else anyway (legally). Such a niche use case really does not matter all that greatly in the scheme of things. I can think of dozens of factors more important to me than "not being able to drive at 200 kph for extended periods of time".

It's not an insane speed, a new VW Golf can handle 170-180 kph pretty damn well, hell, my 12-year old 1.4l hatchback can do 130-140 kph for hours at a time quite as well, too.
It's insane because it's way too fast (thus potentially dangerous), not because vehicles aren't physically capable of it. The occasional driver roaring down the Autobahn in the left lane at 200 kph is the exception, not the rule.
