There’s a time of research about the risks of context-specific controlled versus dedicated buttons in cars. Eg
I can’t claim to be up to date with it all but I do know that the baseline is that touchscreen is massively more dangerous than dedicated physical buttons. The system Bahnoff describes sounds like the designers there are trying to address a lot of the key risks, though.

Voice activated is even more dangerous than touchscreen at current technology levels, based on what I was reading about six months ago. It’s to do with the problem of “not good enough” technology. Unless the ability to speak to the machine is entirely natural, your brain gets massively distracted trying to identify the exact correct words in the exact correct order to achieve the thing you want to do. That’s very unnatural and requires a lot of cognitive processing power.You can do pretty much everything with voice commands in the iX (and the X5 we had before it) so the buttons/knobs/screens are mostly irrelevant.
