Bah, a few million American motor vehicle operators are not the heart and soul of the oil industry. You're worrying about nothing. While we're likely to play more with electric vehicles moving forward, there are still entire continents that are rich with resources and feature populations many fold that of the US who will continue to burn petrol because they lack the infrastructure to support EVs. That will be the market for the oil companies, and the consumers will pay because it's no different in Calcutta than Dallas as long as the conglomerate gets their cut. The idea that the oil industry will lose all of its customers over electric cars in the US is simplistic. China, India, Brazil and the whole southern continent, Africa, Asia... They'll buy the gas long after we stop, and Exxon will oblige. You'll still be able to buy a tub of bearing grease when you need it. Whether you will still be able to buy a 1/2 lb of Angus beef on a bun is a much different question.
