Because, objectively speaking, Consumer Reports, Car and Driver, and thousands of actual Tesla owners think that the build quality of their cars is crap. Literal 90's era Kia crap. And notably, unlike Munro, CR and C&D buy their cars anonymously so that Tesla can't goose the reviews.
Tesla has the highest consumer satisfaction ratio and the highest costumer retention ratio in the industry.
Objectively false, and indeed Tesla's abysmal customer satisfaction (nearly the industry lowest) is one of the reasons why CR stopped recommending Teslas.
Tesla have top ranks in safety
As does every other EV with a frunk. And a number of ICE vehicles like Subarus. The safety review tests rank cars collectively, so Tesla are in the top rank but are not the top-ranked, because that's not how the safety reviews are scored. And to claim otherwise is just another example of Tesla's deceptive marketing.
Their structural engineering with their castings is ahead of anybody in the industry.
Yes, it's so good that the Cybertruck has been delayed another year because Tesla discovered that they don't actually understand how structural engineering works. (Here's a hint: car panels are shaped and curved because it provides additional strength; creased flat panels are actually the weakest design you can use for automotive purposes on the basis of mass and need tons of reinforcement.)
They have the largest global fast charging system and the single best integration of cars and charging.
This is the only true statement in your comment. It's too bad (for Tesla) that they're planning to eliminate their only competitive advantage by opening it up to everyone. (Literally the only reason the several dozen Tesla owners I know still own Teslas instead of better EVs is because the Supercharger network is 10000x better than the alternatives. They're willing to put up with the shoddy build quality of the car and the absolutely horrific customer service because the charging experience dominates.)
