They learn to sort of coast. The car feels like it's coasting. Sure.

Next time you do this keep an eye on the actual power readout. See if it's actually zero or if it's reporting ~3kW of braking or accelerating.

It hovers depending on how my foot modulates the speed. I don't want or need "exactly zero power readout", I only need to reach my target speed at my target spot on the highway, without having to action the physical brakes at any time.

Whether that is more or less efficient than a zero-power coast followed by some kind of braking exactly at the end... I assume the difference is so tiny that it makes no difference.
