The context switch isn't bad (admittedly it is more). The touch panel has almost everything you would want to do commonly in only two taps. Navigation: The cognitive load is very high on both vehicles. Using dials and buttons on my Audi is really hard and the maps are loaded with random icons and its a bit harder to parse where I'm supposed to turn next. The voice directions work really well on the Model 3 since I assume it just pipes it to Google Maps. My Audi is terrible unless it is "home" or something obvious it wont misunderstand. AC/Heat: I have to look down for both cars. In my Audi, the physical buttons for the fan have digital displays for the speed and temp. So I have to look and read anyway. Music: There are next/previous and volume buttons on the wheel in the Model 3. No different than my Audi. Tapping the giant screen is definitely easier than tapping on my tiny iPhone screen like I currently do in my Audi.
