If that human with cruise control is me, I will beat the cruise control by never activating it. Because there are dips in the road and breezes are not always steady. A mindless machine that varies the throttle setting to hold an exact speed is not as efficient as a human that allows the subtle effects of a gust of wind or a slight dip or slope to temporarily affect the speed of the vehicle without coasting or going deeper into the throttle.No. You mishear.
A Human with cruise control always beats a Human without.
More on topic: A common misconception is that a coasting EV is not sending power to the motor. That is false. The permanent magnet motors cannot coast freely without a small input of power. This means the most efficient way to drive is to avoid regen and avoid coasting. When I put my Model 3 into "Neutral" it is a simulated neutral that is achieved by powering the motor enough to neutralize the inherent magnetic drag. But no real work is being done at the axles. The area of the power curve near zero torque (near zero HP) is a very inefficient part of the power curve. Thus, in an EV, it's most efficient to hold a steady, light throttle, even if that causes the vehicle speed to vary up and down a bit.
