Although certainly moreso in stop-and-go driving than in highway driving.
Also, not remotely true if you ever drive on hills which are so large, steep, twisty, or traffic filled that you are forced to brake / engine brake on the way down, or which have stop signs/lights on the downhill or soon after on the flats, in which case you never recover the extra energy it took to go up.
And maybe I just live in a hillier than average place, but it seems at least one of those conditions is true on an awful lot of hills.
