The touchscreen isn't the problem, having a screen at all is the problem. I have a Mazda and hate their scroll wheel interface, with a touchscreen I can just press the "AM Radio" icon, with a scroll wheel, I need to turn the wheel then keep looking at the screen to see where the cursor is so I can click the right icon so it takes more attention -- both cognitive processing (how many clicks do I need to turn to get down to the button I want), as well as visual (is it on the right one yet?) Voice recognition is even worse, I often end up having a conversation with the car "Call George" "There is more than one George, which one do you want to call" "George Modaline" "Ok, Calling George Smith - mobile".
