From a human factors perspective, touch on a phone would be different than in a car. A phone’s button locations are fixed, so you can locate each one by touch. Even with the current buttons, how often do you simply grab your phone and operate one without looking at the phone? Other than the loss of tactile feedback, assuming no haptic device, the action is the same with touch controls.
In many car implementations, such as CarPlay, there is no fixed location for controls nor tactile feedback, so you have to look at a screen to identify where to touch to get the desired effect; which is frustrating and unsafe.
