Sandy Munro lost all credibility when it came out that, while going on about all these wild claims about Tesla's incredible manufacturing prowess and how everyone else was shit, he held a fair bit of Tesla stock and even went on to gloat about how much he made off it during 2020.
Absolutely zero integrity and no reason to trust a single word he says anymore, because not only has he shown that he won't disclose serious conflicts of interest, but that he'll also gladly abuse them for personal gain. He realized he can make way more money shilling Tesla and selling merch than he ever did with his normal business, and rides off his company's past reputation.
Even if you ignore that, his analyses are basically entirely cost focused, and having seen some of the reports on projects I personally know quite well, he takes an incredibly simplistic view towards component design and focuses on almost entirely on cost/simplicity, with basically zero regard for longevity, function, NVH, etc. Which, for the massive 500+ page reports that are purely for cost and build analysis, is totally fine. However, he then spouts it to the public as if everyone else is an idiot for not wanting their cars to be rattling shitboxes.
He'll praise things like Tesla re-using the suspension from the Model 3 1:1 onto the Model Y because it saves on manufacturing costs and such, but will completely ignore that, until some fairly recent part changes, the Y had literally one of the single worst rides of anything on the road today, because they added 100s of pounds of weight and didn't even bother to change the spring rates.
