They are battery cars. They run on batteries. And the lithium reserves can only create batteries for about 10B leaf cars. Total easy lithium is 4B. via the water evaporation salt flats technique.
“And the lithium reserves can only create batteries for about 10B leaf cars.”
Lithium is one of the most common elements in the Earth’s crust.
It is expensive now because we need to build new capacity, but long run it won’t be any more expensive than table salt.
Batteries are the biggest problem with the EV concept.
