Nothing you've said actually runs counter to the parent comment, though. Tesla can simultaneously be awful at logistics and still be the largest battery pack manufacturer because no one else really wanted to get into that game until recently.
Also, the gross margins on the Model 3 have little to do with supply chain. They cut a lot of corners on build quality, interior fit and finish, etc. to get to that margin and they're only able to do so because of lack of competition in the segment.
They cut corners but have the highest safety rating ever and the highest customer satisfaction?
Is it reasonable to call something a cut corner when the end result is success by nearly every metric? Maybe that corner needn't exist? Scaling issues are unavoidable. So much nitpicking.
When body panels don't line up, doors don't close properly without slamming them, and your infotainment system randomly bugs out (all issues I saw when borrowing a Model 3), your vehicle manufacturer cut corners. Meanwhile my distinct impression of interior quality when sitting in one is that it's basically a mass market car with a leather option, not a luxury price point vehicle.
And no, scaling issues are absolutely not unavoidable. These are all solved problems. Tesla just rushed vehicles out the door with crap production line QA because they were running out of money and market patience.
It's really annoying when you twist commenters' words to suit your agenda and go straight to logical fallacies. I'll ask you to please stop doing that. No, existing manufacturers do not ship 100% flawless vehicles, but the average build quality of the ones they actually sell to customers is significantly higher than what Tesla is pushing out with Model 3. A five second Google search for "Model 3 Quality" will show you this.
His argument was some vehicles had flaws and that can be avoided. Who avoids it? That's not even a partial twist.
Moreover, both of your responses ignore my original point of customer satisfaction. If this were a major problem, why would they have among the highest satisfaction?
