Or to simplify, aim to maximize your minimum speed, rather than minimizing
your maximum speed. In other words everytime you have to slow to a halt,
that
fuel wasted having to get back up to speed after. You might find you make
better progress too, by passing transistion points like traffic lights
turning green at 15mph, rather than from zero.

It still goes the other way too.
If you are going to have to slow to 0 or 15, its still better to do so from
25 or 30 rather than 35 or 40.
