I don't like Trump either. But as others here have said he didn't say this. That's a quote from the article the quote from him says "You won't be able to sell those cars" not "I'll ban all electric car sales"
Why are people downvoting this? Trump is a literal poison, but misinformation is misinformation. The author changed the meaning:
"You won't be able to sell those cars, because they won't have EV incentives" NOT "because I'll ban them."
I was not saying he is correct, saying that was his likely meaning in this context. He's not exactly got a great track record of being smart or correct. Just in this case he didn't seem to mean a ban outright.
