NdFeB PMM are generally accepted as +15% more energy efficient, with advanced motor controllers this efficiency spread is likely to grow.
The real cost of induction substitute is reduced range or the cost of additional battery capacity, both significant to the customer, Elon certainly worked that out.
Hardly see "the struggle producers outside of China will have" given superior IP NdFeB & motor controllers, albeit diminishing, particularly if ROW Govt's wake to Chinese trade manipulation and level the playing field.
Watch for US action on that one, lead by Katherine Tai.
