Colbert had it right. It's all about "truthiness". It doesn't have to be objective truth. It just has to feel right. The Fox audience doesn't like EVs, doesn't want to believe there is anything good about them and they are very willing to go with the idea that a major auto manufacturer is selling a brand new vehicle for $10,000. So it passes the truthiness test and they won't hold it against this Fox guy or anyone else.
