We do indeed see infotainment systems in cars that are the direct analogues of cell phones and cause distracted driving. They even connect to the phones and give similar touch screen apps.

These systems are legal but using the phone is not, so this really is a great example of trying to regulate technology rather than outcomes. All that happens is vendors put ports in their cars and route the phone interface to the driver in a fixed screen rather than in the phone's screen. Regulation bypassed.
