While I agree with your overall point, I think there's even lower hanging fruit that's still not picked up.
In France, at least, when there are more than two lanes, basically no one drives on the rightmost lane.
Yes, I know about the traffic law requiring staying in your lane if there is dense traffic. I'm specifically talking about the case when there is little to no traffic.
That's a huge issue too in the UK, especially on three lane roads and wider, where you can just sit in lane two forever, if your skin is thick enough, and everyone will just have to over- and under-take you.
It's actually been illegal for some years and can get you a £100 fine, though I don't know if that's ever actually happened: you'd have to have the bad luck to encounter traffic police who do anything other than speed-gun free-flowing motorways from bridges.
