"For the next BMW car everything is rebuilt from scratch" does sound very different to me from "the system is developed by a different company in each multi-year cycle that covers dozens of models". Maybe you're trying to tell me that I should have understood that you couldn't really mean what you wrote because that's just absurd? In that case you may be right. I guess that when you say "nobody is iterating on anything" you cannot really mean that either - because it's just equally absurd to think that completely independent systems were designed from scratch multiple times without any reference to the previous ones and it's just by chance that the first version had a dial only, the next "non-iteration" a similar dial and two buttons, later more buttons appeared, etc.
