I promise you both work just fine it designed properly and placed properly.
Example, 2017 Chevrolet Volt. Center stack UI was nice to look at it but many options required multi level drill downs to change. HVAC controls were at the bottom of the center stack. Forty plus buttons between steering wheel and center console and this does not count all functions on stalks. Z4 I had had three stalks and forty plus buttons with heated seats at bottom of center stack and under.
Touch screens like anything else in the car that a user interact with can be bad or good.I found Apple Car Play when used on the Volt to be obnoxious and far more requiring me to take my eyes off the road.
I keep emphasizing one thing that people keep ignoring. You rarely if ever have to use the touchscreen at all. Almost every setting is set and forget. You catch glimpses of the navigation and such from normal eye movement. let alone, lets get real silly here, the TM3 can drive itself in traffic just fine if I wanted to get stupid and take my eyes off the road.
Well since you bring up heated seats, the TM3 does not turn on the heated seats automatically based on temperature / butt-in-seat and changing it requires 3 touchscreen taps, two of them high-precision taps, where as the Volt has simple tactile controls. Though I will say the Volt has some of the worst climate control UI I've ever seen.
Similarly the defrost is not automatic and the button requires a precision tap.
There are a couple of reasons you might need to actually use the controls in a car with some regularity.
