Here’s a screenshot of Musk’s missive, which he later followed up with a tweet urging people to watch the 2006 documentary “Who Killed the Electric Car?”I saw that movie, and my recollection is that California regulators tried to artificially create a market by requiring the car companies to either sell a lot of electric cars or sell none. The companies decided that the minimum sales could not be met, so they had to abandon the electric cars.
Musk's company depends on huge subsidies for all its sales. The subsidies are based on a theory that the cars are good for the environment, but nothing that expensive is good for the environment. If you pay a lot of money, then a lot of resources will get used somehow.
