Only the last of those really is improved by touchscreen. Except for navigation, most of those (and more, like answer the phone) can be done from analog steering wheel controls on a Hyundai or a Mercedes. Hyundai locks out navigation while the car is in motion and a context switch is avoided by a split screen function that allows both at the same time. Hyundai also features limited voice recognition (call Mom) which is an under utilized control method in my opinion. https://owners.hyundaiusa.com/us/en/resources/blue-link/voice-activation-system.html https://owners.hyundaiusa.com/us/en/resources/blue-link/voic... When in doubt, designers should see Kia/Hyundai. They ain't fancy. They just get the job done on a very simple, practical, subdued level --- which wears well over time in my opinion.
