I think a big portion of the root cause comes from the years of Russian astroturfing of the conservative online spaces. Russia is bigly into oil marketing, and supporting the usage of oil is aligned with their national interests. They have been basically brainwashing conservatives to support oil companies for many years, and now it's part of their cultural identity.
But if you applied classic Conservative principles of conserving individual liberty and being self-sufficient, it becomes obvious that having an electric car would be an advantage. You can make your own power at home and be free from dependence on gas stations to power your freedom to travel.
There's plenty of American oil propaganda too. Oil companies around the world have an interest in encouraging people to treat gasoline consumption as part of their cultural identity.
