Many manufactures already offer this, Mercedes, Tesla, etc... Many of them are not given good reviews for usability vs a normal control layout with knobs and buttons.I've recently been thinking about a project for a smart car dashboard and I designed the UI interface. If there was really such a dashboard, would anyone use it?
I think redundancy (with traditional controls) is a must as well. What happens when the screen is kaput/malfunctioning?I personally dislike touchscreens in cars, for all but the most trivial functions.
Unlike tactile buttons/knobs/switches, they require you to take your eyes off the road.
Right now, I can adjust the A/C, window up/down, work the radio...all while still looking out the windshield and driving the car.
Then you bring in a whole host of other issues:
Gloves in the winter, bumpy roads, screen calibration...
