The way I see it is Tesla is trying to target its future business in the battery and components for EV instead of making cars. That's why the open patent and giga factory. If everyone else build EV and buy components and battery from Tesla, that's more easy money for them, but for now they need to keep building cars to scale up.
They are too expensive and I suspect a Sovereign fund or some funny money (political) is keeping it going. I'd not say it will collapse soon but it may not be a while before it will be self sustainable.
Japanese avoid layoff, that's why 1/3 of their workforce are contractors and temp. Their young people are now in the 2nd lost decades, and corporate holding onto bad loans and bad debts without write off or growth.
$15000 new car that will last 20 years with little and linear depreciation is a screaming bargain, even a $23k hybrid that last a long time with high mpg like Prius is a great bargain, just ask the cab drivers.
