Yes, you still have to drive safely. That's a lot more nebulous than just looking at velocity numbers.
Another thing to keep in mind, is that if you drive fast enough in Germany, and anything happens, the burden of proof shifts: the (extreme) speeder is presumed guilty of causing the accident until proven innocent.
Fun fact, the incident you linked to happened where I grew up.
Unsafe driving by itself is against the law in Germany. Even if no one was hurt.
You can argue that the law is bad and just be repealed, of course.
(Or like the guy in the article, you can have your lawyer try and argue in court that the law doesn't apply in this case. As a competent lawyer should in a fair trial.)
Not sure any politician was involved in the first place? Though of course politicians might utter opinions on the whole thing. As they should, so that voters can decide who to vote for, if they are in favour or against this law.
