They're not doing that, either... the only reason you would drive a Tesla is performance. The environmental impact of making a full-EV is much more damaging than using a gas engine.

I thought it's widely accepted that the Tesla stock price is heavily inflated relative to the company's actual performance and that Elon Musk is increasingly considered a liability as his vaporware marketing (e.g. the various blatantly misleading claims about the trajectory of FSD capabilities) was a major factor to the stock's growth in the past.
I wouldn't use what Bill Gates is investing in as any indicator of what we should be doing.
