Greg is a Tesla hater so it's not satire.
Greg is an interesting case, he presents himself as a race car driver and instructor, so a professional driver that is used to performance and may have a wider range of experience as to what other higher end cars are like than I do.
He actually was advocating for Tesla for a long time, when he got his performance model 3, and it was blowing his mind. He would tweet things that I could totally relate to like 'Driving this is like having god mode in a computer game, you have the unfair advantage every time'.
But he also was getting frustrated with the quality of autopilot on the streets of SF, he expected a lot more, and found that when he spoke up, the fanboys that did not have the same experience or expectations don't really seem to acknowledge criticism and explain away issues and experiences that he had.
I can only speculate here, but it seemed that intensified when the stock price started to take off, and he fell prey to the negativity of teslaq which at least would listen to issues he identified. Maybe he sold Tesla stock too early and never got back in. Who knows, but it looked like a 'the grapes are too sour' kind of reaction to me. He always was worth following because he would say provocative things that sometimes were brilliant, but after this time period, he also started to repeat FUD and misrepresentations in a bitter way. Always talked about how he was going to buy a mach-e as the next car instead, but then in the end did express that he saw better value in the Model Y when it comes down to him making another purchase decision. And yet keeps repeating the mantra of teslas overvalued, FSD a lie, panel gaps, Ford and VW are going to start mass producing better cars any time now etc. He eventually blocked me on twitter when I gave my version of reality a few times. Not sure if that is why, or he adopted teslaq blacklists, or for other reasons, i.e. my political retweets etc.
I wish him all the healing he needs.
