Trump makes asinine statements all the time. On the other hand, at least he doesn't forget what he is saying mid sentence.
I think you sort of need a Trump translator though whenever he speaks as everything he says is hyperbole. I doubt he really means that he will somehow personally magically end EVs (though I could be wrong). He may mean he will oppose subsidies for EVs and/or try to stop laws mandating EVs and/or something similar.
