Hi Paul,

What I believe Les is referring to is that the fuel efficiency versus speed
curves for internal combustion engine vehicles is rarely linear.

A profile often seen is that the economy starts poorly at low
speeds, gets worse as you start to go faster, then at a sweet spot where
you might be cruising in overdrive it can improve and then if you push
it beyond that in speed the efficiency drops off again.

The gears are trying to match the limited optimal spot in the power band.
