I think part of it may be a nationalism thing. People don't like to mention it, but EVs are doing insanely, incredible well in China, and China is increasing the amount of car exports it does as a result by huge amounts (seriously, Chinese car exports five years ago to today is an absolutely incredible accomplishment, check out the graphs sometime). I believe currently in China 30% of all new car sales are EVs, and it's not showing any signs of slowing down. Pretty soon, that should mean petrol cars in China enter a death spiral where it's unprofitable to keep service stations operational and filled with expensive underground fuel storage because demand for fuel is falling so filling up gets harder and prices get higher, then because filling up is harder and prices are higher EVs become even more attractive, rinse and repeat. They are well on track to that, while here in the Anglosphere we're stuck at "only" around 8% of new car sales (still very impressive compared to where it was five years ago).

Basically, China is doing a better job than us, therefore the job isn't worth doing anyway and frankly who even cares about competing? I'm going home, and I'm taking the ball, and you can forget about my birthday party too.
