so I worked in the automobile industry in a prominent company working with all prominent car manifacturers, and I was one of the PMM experts there (the dynamic electrical motors).
By far the best PMM's worldwide are made by Kessler, Germany. They are way ahead of everyone else, but they can only manifacture about 200 units per year. Hand-made, like a Ferrari. Many of these PMM's for Formula 1. All the good german carmakers know about these very well, the prices, principles and tricks. They are far ahead of most others, including Tesla.
What Tesla did well was bringing parts of this technology to market. In record time.
