"their profit margins on each vehicle are higher than any other mainsteam auto manufacturer "

ahem no that is not true. They are small no matter what margin definition you are using. No other OEM uses Teslas "automotive margin" definition.

Toyota for example has a net margin of 5.51 % That is 2.91 times higher than Teslas net margin. And Toyota sold over 10 million vehicles last year. Tesla like 370K.
