Hey, I just bought an EV two weeks ago, and the main reason I didn't get a Tesla was Elon. So, I can't speak for other EV car buyers, but this one definitely cared about Elon's "incendiary personality" and not wanting to support him.
I'm a only a single data point, but: I was recently in the market for a new EV, and the biggest reason that I didn't go with Tesla was Elon. Full stop.
