An interesting use-case could be localized haptic feedback on the screen. You could rotate a knob or push a button on the screen and get a localized sound and haptic feedback from the item on the screen.
You may even add haptic texture on the screen. close your eyes and scan the screen with your finger. It would feel like a series of mechanical switches and knobs. It would be useful for people who don't like using only the screen in their car because of lack of haptic feedback.
