NHTSA spells out what your phone shouldn’t be able to do whiledriving

I don't know when being the driver of a potentially lethal weapon required that they be "entertained" while doing so. IMO, there is NO need to be able to call/text/facetime someone while you are in traffic. And the gigantic displays are just as much of a distraction as the phone.
If you want to have fun behind the wheel, take a taxi/Uber/bus and sit behind the driver.
