Some things can be done quicker with physical buttons.
That's why people thought phones with just a screen would never become popular: https://www.youtube.com/watch?v=eywi0h_Y5_U
But with a screen you can do many more things.
A driver has only a few things they need to do while driving (beyond paying attention to the road) Menu diving to turn up the AC is just a fundamentally terrible idea, but car makers don't seem to care?
I saw a recent Marques Brownlee review of his $130k Tesla S and Every. Single. Control. in the interior is a capacitive button. Absolutely insane to offer no tactile feedback
My position is that cars should be optimized for safe driving until they hit L5 and we’re comfortable saying they don’t need a human driver. It’s one of the most dangerous things we do and should be treated that way.
It seems the concept of cars also change:

I watched this in the morning today, and in the 38 minute ride, the guy was mostly doing other things. Recording a video etc. In the whole ride, I think he only did something related to "driving" for a few seconds.
Being distracted during a phone call doesn't pose a risk of grievous injuries or death to yourself or others. Unless the nature of cars fundamentally changes, they should not under any circumstances be cool entertainment devices. Your focus should be on your mirrors and the road ahead. Full stop.
Computers are extremely good at calculating physics. And they never get distracted.
