No idea! Would it be expected for an electric motor to lose so much efficiency in that scenario, though? I though the variation was small. Motor efficiency aside, a total “energy spent for distance moved” accounting will look bad at such low speeds, just because the car has to power non-motor systems and they use energy at the same rate no matter how fast you’re moving. Peak efficiency in a Tesla is at around 25MPH.
