Disagree.

Personally, I feel the problem is absolutely touchscreens.

I've only got five senses, and taste and smell aren't helpful in a driving situation.

Of the 3 left, sight is the most important for the most important task: driving.

For other tasks, sound is best used to alert or remind about something, and is frequently diminished as a driving aid by music.

That leaves touch and sight for all remaining tasks.

Touchscreens are, despite the name, effectively 100% reliant on sight, since there's no real tactile feedback to enable the user to make eyes-free adjustments. To use a touchscreen, you have to take your eyes off the road to see what the screen says and make your selections.

While some are better than others, I also feel like touchscreens are still embarrassingly and frustratingly prone to errors, missed touches, and generally not doing the things the user intended, requiring even more eyes off the road to undo whatever actually happened, get the interface back to the place you want it, and try again, hoping that this time it'll work.

My mid-teens vehicle has a mix of a medium sized touch screen for the entertainment unit but physical controls for climate, driving, and a few of the entertainment adjustments, and while I was all about the advanced new touchscreen when I bought it, I find it's my least favorite part of the controls this far along in ownership.
