You are being disingenuous. Of course some of your points make sense in certain circumstances.
> we should ban talking to your passengers on a car too, right
That genie is already out of the bottle and would be impractical to implement. In any case it far less distracting talking to a passenger than trying to reply to a text or conducting what may be a serious conversation on a phone. Additionally the passenger can shut up instantly if (s)he sees a situation developing or even help bring your attention to it.
> both having a conversation and listening to music keep me alert when driving
On a long, boring trip, with very little to concentrate on, it can make sense to have the radio playing and someone talking to you. However on a rainy evening, in fast moving traffic, that same radio and passenger could get you killed and others with you. It is easy to turn off and ignore the radio and to ask your passenger, who can see the danger to please keep quiet for a while. It is a lot more difficult to ignore your phone when expecting that important call under these conditions.
> far the most distracting thing to me while driving? Constantly checking my speedometer
Seriously? Glancing at your speedometer is more distracting than a phone? Besides, glancing at your speedometer for a second carries far less risk than answering a text and having a fight with your girlfriend on the phone.

If they know what to look for. Doesn't work with children, people who don't drive themselves so they have no idea what to look out for, or even worse, it can work the other way around, when someone yells "WATCH OUT" at the top of their lungs because they perceive danger, even though you were not in any(saying hi to all my elderly relatives here).
