Anyway, there are no billions of new middle class people ready to buy a car there. You are far, far overestimating the growth potential and at the same time underestimating the current rate of vehicles ownership (mostly two wheeled).
Electrification, certainly, more A/C definitely, more cars, sure a bit but infrastructures are already under heavy load which limits the interest. Billions of cars, never.
it's a lame balancing act by the elites who based all their livelihood off masses of people to explore, and the need to be sensible with resources to keep the status quo a little longer.
china, when they were briefly communists, put a population limit as it was sensible when the plan was to make everyone enjoy the benefits of society. ...then they jumped to capitalism as usual and changed gears.
