Same with going from 99% to 99.5% efficiency. It still reduces the cooling needed by half.

> reducing the need for cooling by half
But the motor is not the only thing that needs to be cooled. It’s mainly the battery, which has a narrow operating range. The power electronics that convert AC to DC also need to be cooled.
So you’re halving the cooling needs of the motor, which is nice but small compared to the other two. And even then, total cooling doesn’t impact range that much compared to warming the battery in cold climates.
I think you’ve overstated your case.
