Driving is one place where tactile feedback really matter and touch screens are a POS. If the driver has to take their eyes off the road to change the radio station somewhere someone will get in an accident and die. On my G35 I really do not like how all of the radio preset buttons are smooth and flush next to each other no matter how 'nice' it looks. It makes it near impossible to push the correct one without looking. I added little bumps via super glue so I would know which button is which without having to look. Going out of your way to add a generic ipad that is designed to require you to be looking at the screen and not the road is a bad mix. You could use it as a glorified screen and have special software that always ran and connected to the car via the usb port (exists on the iphone) and didn't let you do anything when moving that would be in a step in the right direction. Still, adding a distraction to the driver is usually not worth the risk.
