That is a strangely aggressive response - I'm not claiming every single ev is pmac but many are. What sort of motor do you think a Tesla model 3 uses, for example?

Even considering that, induction motors also have an efficiency curve which is the point I'm making. If you care about efficiency motors have a sweet spot. Sometimes you care a lot about that, sometimes not.

They went into a lot of effort to optimize it over RPM range.

If you want to make a point use real motor curves at least. Your graph suggests it goes to sub 20% efficiencies at low speed which is completely false and would suggests way higher gains from gearbox than in reality. Hell, it would suggest ICE like performance, it's THAT bad.
