Here's the real issue with that thesis. The EV technology is actually the easy part of the equation. Designing and assembling automobiles competitively with the likes of Toyota, Honda, GM, Ford, etc. is what they're up against....all of which can produce EVs at a rate that can flood the market and still make up a very small percentage of total vehicle production. The majors also can do so at a loss, being able to write it all off (figuratively) as R&D and image advertising. That is a tremendous barrier to entry for any company, especially a small undercapitalized one.
There is a romantic notion that comes with investing in car companies. It's glamorous. But it's a terrible place to put your money. There's a reason why most of the brands of the major automakers are former defunct companies. It's where capital goes to die.
