What's false about it? I drive through Germany regularly and there are stretches of the autobahn where there's no speed limit, I've driven at 130mph past police cars and it's absolutely fine - are you saying that the "big" part is false?
I'm commuting every day through the a section of the Autobahn where the speedlimit is 130km/h and some sections go as low as 100km/h. Posting about personal experiences is obviously equal to inflamatory trolling and should be voted as such.
Ok, then ignore the second part of my post. I'm asking what exactly is false about saying that big parts of the autobahn are unrestricted? Which part of that sentence is false?
