> If it is not profitable for companies to build such infrastructure
I didn't say the government would build out charging infra, did I? But they can make it easier.
> most of the world can't afford such cars either due to price
The sun is free. Oil costs dollars. Most of the world is dollar-constrained. Until now capturing the sun's energy was costly, but China's manufacturing scale has changed that.
Their manufacturing scale has also produced EVs that are way cheaper than your average Tesla.
> and/or due to non-existent infrastructure
Most countries have cheaper labor and fewer environmental constraints than the developed world. If they have a reason to build infrastructure, they'll build it.
