it’s not about tactile feedback, it’s about motor memory. Fixed controls promote motor memory. Your limbs just know where to go when you want control “x”. Touchscreens, and particularly those with multiple levels of controls where you have to navigate to find a control completely neutralise that, so you need to divert conscious thought interacting with them.
One of the things we do is control room design, and extensive usability studies on “man machine interfaces”. Critical interfaces for work requiring high and uninterrupted concentration absolutely required motor memory to minimise distraction. You don’t get that from programmable interfaces. Is like trying to touch type on an iPad. No physical cues to facilitate digital navigation without optical assistance. That requires concentration.
In case it isn’t obvious I’m anti-touchscreen in critical applications and I consider driving a car a critical application.
edit: it is about tactile feedback where it is used as cues to facilitate motor memory.
