One of my fundamental criticisms of Elon musk performance as a CEO. The vast stock market price and valuation should enable these sorts of transactions.
It would enable Tesla to diversify operations move into applying its technology on a mass-market basis to hybrids without "damaging" the "purity" of the Tesla brand.
It would enable more marques to target specific economic bands, international markets, etc.
But no we basically have a car company that makes two cars.
Elon Musk has completely lost interest in being CEO of a car company. Tesla is a whatever's-on-his-mind-today company.
