I was surprised to find OP didn't cite what I believe to be an even more existential threat: the rise of Tesla's bit-based cabin vs. the atom-based tradition of legacy makers. Compare the Model S with its elegant, minimalist, understandable layout vs. the latest Mercedes-Benz S-Class cabin, which resembles a miniaturized version of the space shuttle: countless dials, screens, buttons, switches, levers, and lights above, in front of, below, and to the sides of the driver.
You imply that traditional dashboards are too complicated. However, Tesla is merely hiding that complexity behind one or a few screens an a few buttons. I like the approach to minimalism, but in my opinion there has to be a balance between pragmatism and beauty. The learning curve and ease of access is just lower in German (or traditional) dashboards in general. I am not sure if Tesla found that particular balance. I hear a lot of hate towards the giant screen and no love, but that is just anecdotal.
I assume Tesla went so radical in the Model 3 to save costs, rather than to stay minimalistic.
I agree with the parent. The UX of the Tesla Model S seems like a cohesive design from a coordinated team. The 2018 Audi S4, lacks the cohesiveness and the UX is a bit overwhelming.
