If you're going to make authoritative comments about motors, you should actually get your facts correct first.
>The Model 3 does use a permanent magnet motor, but it's an AC synchronous reluctance motor.
No, synchronous reluctance motors do not use permanent magnets on their rotors. The motors that do are called "brushless DC motors". I'm not sure what the Model 3 uses, but last time I saw a cutaway, years ago, it was using an inductance motor, which is entirely different, but maybe they switched to BLDC for efficiency gains.
