There is also a chance I won't buy a car without knobs. Car software has been historically so bad. My latest doesn't have a volume knob so my front passengers can't turn the volume at all (the UX is sliding the screen from the side to get navigation bars to appear which contain a volume button that you have to drag laterally - no increase/decrease software buttons). Otherwise it's a great car and that is literally the one drawback.

I must be the minority surely, but given the choice between knobs and screen, knobs are the deciding factor. Even if it's more expensive, it's UX that you use permanently while operating heavy machinery!
