Tesla has dominated the large luxury car market for years, and they rate at the top in customer satisfaction, too.
If Musk were happy with that, Tesla would be a nice little profitable company. But he’s a big risk taker and he does have a big vision. He’s been investing in the expansion of the company and new products. That’s why they aren’t profitable yet.
I don't know exactly what you're referring to, but the big three in luxury cars for 2017 were Mercedes, BMW, and Audi. Maybe you're talking about a specific 'size' of luxury car? Or are you talking specifically about 'electric' luxury cars? Anyway, when you receive multiple billions of dollars from the taxpayers you have a responsibility to deliver profitability in a reasonable period of time.
