Stats say that the Autobahns in DE are no more dangerous than any other road. The only place there are no speed limits on the Autobahns is in the country. I’m quite sure they have more pressing problems!
Living in New Jersey at the time, I found the Autobahn safer than driving in New Jersey, even when hitting 220 km/h. The driving habits were much different. No weaving in traffic. In New Jersey drivers will even pass on the shoulder. Drivers seemed more aware of what was around them. Even now, talking to some Germans, there isn’t the distracted driving problem like here in the States, including texting. But then going 200 km/h+, things happen very fast. And when there is a wreck, it is big.
