I see at least two factual
I see at least two factual errors in here:
Synchronous Reluctance Machines in its pure form is not used in any production car today.
Almost all cars use IPMs, a combination of Syn. Reluctance Machines and Permanent Magnet Synchronous Machine.
Tesla is not alone with segmented magnets, almost all EVs use that feature in the rotor.
Also, you forgot to mention the Externally Excited Synchronous Machine, which is magnet free, and getting more popular ad an alternative.
