I wouldn’t say its on the lower end. We have the rightmost lane which is almost entirely occupied by trucks which are not allowed to drive faster than 90km/h. On roads with more than 2 lanes the left most is used for anything between 130-200 I’d say. If you are using that lane and see someone faster coming up behind you you get out of the way. If that’s not possible, well they’ll just have to brake won’t they.
The highways are mostly straight as well in germany so curves aren’t really an issue
Most people I see are sensible though unfortunately I have a friend who will (briefly) use his phone even while driving about 180km/h. He’s also the only cop I personally know…
