To be fair, I hate to be distracted by screens even while driving. Even if the car could drive itself with 100% safety while I was operating the device, being forced to look at a screen for a long while just to find the equivalent of a physical switch (or, in the future, to watch a movie?) leaves me a bad taste.
The dashboard of a Tesla is covered with unused surface, so it makes very little sense to put no physical commands on it, and then over-fill a tablet UI with those in the strangest places. The "big tablet" trend just sounds like an interface for digital addicts.
On the other hand, Mazda's infotainment systems (https://m.faz.net/media1/ppmedia/aktuell/technik-motor/27493...) fix at least part of this, which makes me guess what my next car will be.
