I moved to Germany 2 years ago, and was afraid of highways being like Mad Max, but I was positively surprised.
Most drivers are very attentive and skilled, keeping the rules, driving safe. I like it much better, than Eastern EU, where people are also going 150+, and are being assholes in the meantime. The upper limit of 130 just puts stress on me, because I obey the laws, but the giant SUV in my ass flashing their highbeams does not. In Germany this barely happens to me, most drivers are polite and safe, even in expensive sports cars.
I really came to enjoy the liberating feeling of driving at my own (and the traffic’s) pace on the autobahn. Yesterday I was travelling between Dusseldorf and Berlin, long open stretches of 3-lane roads, with only a few cars around. I was going around 200, yet I saw a car far behind me coming up fast, some polite flashes of lights from the distance, I pull to the right, and let a Porsche pass me quickly.
I might sound like a carbrain, but I’m not. Everybody should try German highways once, so they can form their own opinion, and not judge based on internet memes. I feel 10x safer on the autobahn, than on some shitty Eastern EU highway with a bunch of apes around me, who don’t care about the rules.
