Pff, whatever. If I’ve got a right hand lane to sit in and let people pass I’ll do 10km/h under the limit (90 instead of 100) and save a non-trivial amount of fuel.
The cost-benefit on that shifts a bit if I need to make a longer trip, but for my usual drives in the 100-200km range that’s an extra 7-15 minutes on a 1 to 2 hour trip, which barely matters.
