Earlier quoted context omitted.
It's incredible how the Japanese carmakers were able to perfect the auto manufacturing process and then proceed to hold that advantage for what, 30+ years now? It's not a secret how they did it, it's been studied to death, every manner of technology/expertise/management transfer has been tried, and still no one comes quite close enough to threaten their position.
To be fair, exactly that level of investment in process and conservatism around change is arguably what led them all (literally every single Japanese manufacturer) to miss the boat on EVs. Basically, getting to your last sentence: you have the wrong threat model. Making "cars better" is great if what a "car" is doesn't change. But what the market wants is "better cars".
