Why? When you say prejudice, is it a technical thing or a political thing? It's strange trying to parse the issue - I think of electric cars as a left thing (though Musk's biggest innovation was creating them as a status symbol which doesn't really cut along political lines very cleanly), but Musk as a champion of the right wing these days. From what I can tell, the cars themselves are technically pretty good and seem like a good deal with a tax incentive (the Model 3 at least).
