Most of the time that these things are tested, demonstrates that
talking on a hands free phone is as distracting as using a hand held.
It is not your hands that are distracted, it is your mind.
I am really surprised that these "smart" dash boards are legal.
If you are trying to set the options on the in car computer, you might
as well be driving from the trunk. Even fiddling with a radio that you
have to see to set is plenty distracting. That is why they invented
the push button radio and the "wonder bar" in the first place.

My caddys has wonder bar radios. Also my buicks had Speed setters where you could see the needle where you wanted and I'd the speedo needle hit it. The thing would buzzzzz. Better to use the cruise control.

My wife's Honda CRV has built in GPS. You have to be in park to set it...

My wife's Lincoln GPS is the same way but you can still diddle with
directory structure, trying to find the MP3 you are looking for or
fool with the blue tooth trying to figure out why it didn't pair your
phone, going down the road.

The flip side of that is if they do have an "in motion" lockout, there
is no way to disable it if the passenger wants to change something.
Maybe they need a switch the driver can't reach paired with the
occupancy sensor on the passenger seat or just put all of these
controls over where the glove box goes.
