That does require a lot of observation and anticipation, but in my view that's quite an additional constraint on top of "driving well" -- and quite different skill from safe progress. An interesting exercise. I wonder if the new beast could ever get more than 25mpg. I'm guessing not.
Not going fast? Yes, in general, but it depends on the terrain. In hilly country the downhill bits obviously help to combine speed and economy, but I find it beneficial to use a tiny bit of throttle down the hills so we build up a little more momentum quite cheaply, and this helps us to climb the next hill using less throttle than we would otherwise need. This is better than going down the hill with a closed throttle, and then opening up just as you're starting the next climb.
Apologies: I've rather got away from the matter of poor/thoughtless behaviour at roundabouts. I'll shut up for a bit.
