'He also explained that "I'm a big believer in screens, because I really believe if you want to connect, you have to make the magic work behind the screen." ' I am a big believer in keeping "product people" away from UI design for dangerous machinery. The eyes and the attention of the driver should be on the road. All the audio visual noise from the car is just plain dangerous. I don't want my car to draw my attentio…
The thing that everyone always misses in these conversations is that screens over buttons is a cost cutting measure, not a first-principles design decision. It means the UI can be designed and developed mostly independently of the physical controls, which helps reduce rework. I also expect it reduces costs for manufacture and assembly. I’m in favour of more physical controls, but it surprises me that this rarely come…
Cars traditionally have very generic button clusters, like [0]. It is even very common to have dummy buttons in there. Combine that with today's cars where those buttons are hooked up to some MCU to send a CAN message instead of being hardwired to a function-specific cable in a giant loom, and it is suddenly quite easy to change button functionality quite late in the design process for basically zero cost: you just need a slightly different label print and a small firmware patch!
Or, if you want to be 100% flexible, go with the ATM approach where physical buttons are placed next to an icon shown on a screen[1]. All of the flexibility and all of the tactile feedback! You can even go for a multi-level layout, with a top row of mode selection buttons, a bottom row of mode-specific function buttons, and perhaps even a big fat dial with haptic feedback[2]. Or even go all-out Elgato Stream Deck[3].
And sure, the fact that slapping in a giant touchscreen lets them decouple UX design from physical controls is going to play a big role. But it is by far the laziest and least user-friendly way of doing so. If that's the best you can come up with, you probably shouldn't be doing UX design at all.
