Nice overview, Etienne.
I try to drive 80-90 km/h on the motorway because the EV I bought a couple of weeks ago, doesn't have enough range to bring me to the nearest city and back, so every kWh I can save by driving slowly is worth it (and it only takes 5-10 minutes longer to drive).
When I was driving through Germany and the Netherlands, after having bought the car, there were plenty of trucks driving around 85 km/h, which was perfect for me to sneak in behind (for constant speed and perhaps some Windschatten). But Austrians don't drive under 95-100 km/h, not even the trucks. And so everyone is overtaking me, which worries me a bit, because it could increase the risk of an accident.
It happens even on the Bundesstrasse, where overtaking is more dangerous, where it feels like I constantly have a big Audi or Mercedes just a few metres behind me. And it doesn't matter whether it's foggy or raining, or even snowing. Very annoying.
I underestimated this factor.
