As a veteran of controversies on the Internet, I have never found an adequate way to respond to someone who takes the position that a scientific consensus is really a conspiracy. I don't mean that as a put down, because this happens all the time. Belief in conspiracy theories is really a mind set, and probably one strengthened by neurophysiology (see Michael Shermer's "The Believing Brain"). And once humans get an opinion, confirmation bias sets in to make them tend to believe evidence that agrees with them, and to discount evidence against. Everybody does this. The result, however, is that opinions are hard to change, particularly after people invest a lot arguing for a particular position.
I can see how the original poster went wrong, and the fallacies in his statement, but he's not going to and I know from experience that nothing I could say will make any difference. I suppose I COULD talk about my trip to the Andes and the retreating glaciers. Probably the best example I could give is the controversy over the question of whether smoking causes lung cancer. Nobody would doubt that now, but back in the day people bucked the scientific consensus with great confidence.
Human beings are full of biases and errors in judgment--that's why there is so much variation in beliefs about things that should be easy to decide. Climate change is one of those things that should be settled, but never will be.
Enjoy your Tesla.
