I agree that OPD is better. I disagree that it's easy to coast with OPD.

What actually happens is you wind up decelerating for curves, accelerating on straights more, and otherwise having better control of the car. Holding the pedal in a location where power is neither going to or coming from the motor is very difficult; usually you want power going to the motor anyway to overcome air resistance.

Also, consider that most EVs will automatically regeneratively brake when going downhill with cruise control on. The last ICE car I owned just coasted and would speed up on large downhills with cruise on.
