A steady cruising speed is the prescribed way to drive on a motorway.

Here's one definition of cruising speed (Collins dictionary):

cruising speed
in British English
(ˈkruːzɪŋ spiːd IPA Pronunciation Guide )
NOUN
the speed at which a ship, car, or aircraft travels most efficiently
eg My car has a motorway cruising speed of 60mph.

Some cars I think travel most efficiently at less than 60 (56 used to be quoted). 56-60 is I grant you a long away above 40, but the idea that people should be aiming to drive on motorways at 70 all the time is bonkers.

Can't believe people are trying to arguing this point. engines efficiency ��
"Effcient" dictionary definition :

(of a system or machine) achieving maximum productivity with minimum wasted effort or expense.


Travelling at 55 might be more fuel/energy resourceful, but it misses out the productivity gains of travelling at a higher speed. There is a balance to be struck.
