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.

So the other day we both returned home at the same time again, only now the weather is warm, sunny, with no wind. And I yell to him: You took the car? In this weather?!?
