That data is practically useless because I'm using Google Maps and Spotify connected to my AUX neither of which I think most people consider using your phone while driving.
In CA, the rules are now the same for cellphones and dedicated GPS units. The only exception is for "manufacturer-installed systems that are embedded in the vehicle". Taken literally, this means that if you have an aftermarket CarPlay-compatible head unit, it's illegal to touch it at all, other than to turn it on or off. [1]
It appears that new drivers are also forbidden from even looking at dash-mounted devices while driving. I get that they might be more easily distracted, and unable to give voice prompts while driving, but they presumably also need more help navigating, with advance lane change warnings, etc. Basically, these laws have not been especially well-calibrated, which is not surprising given that this is true for pretty much all laws regarding new technologies.
