touch screen phones prove you do not need to have fixed analog buttons
Touchscreen phones and tablets are all horrible and notorious for not working right whether that's in the form of presses not registering or registering in the wrong spot. Like think of all the design that goes into a decent keyboard, the way keys are differentiable without pressing them, how there are physical marks that tell you where your hand is touching it, and how all this combines into an input device that you don't have to look at to use quickly and accurately (hell, my keyboard no longer has letter markers on half the keys because they've worn off over the nearly 20 years I've been using it, and this doesn't matter because keystrokes are even more ingrained into my hands than literal written text is, but this relies on the tactile feedback of them).
Meanwhile a touchscreen is a flat, featureless surface where nothing has a fixed position, any input may or may not work, and you have to watch it to see where it wants to put a button and whether that button is reacting correctly or prompting another input. Operating traditional controls that require a hand to be removed from the wheel, like for a car radio or the AC, is already considered a dangerous hazard that's only tolerated because it has to be; making that at least an order of magnitude more distracting is a catastrophically bad idea.
