Just mount your phone GPS to the dash / window, problem solved. Or, use voice recognition ... almost all phones have it.
Seriously, one would have to be blind, and or stupid - to not see that they're slowly phasing out the legalities of having a phone in the car. Too many idiots are always texting their mates in one hand, with their other on the wheel. Oh, and don't even get me started on women, I've seen them nearly drive onto the footpath whilst doing their bloody makeup
The bottom line? When you are driving in the car, focus on the road. Not the kids, not the phone, not the makeup - the road! Your bad day isn't an excuse for someone else to get killed
