As wonderful as waze is, there are times when I wish I could handle phone calls, messages and change songs while driving which become a little tedious and I usually have to pull over.
I think this feature would make it even better in future versions.
To have a car dock interface (like some seen here: http://reviews.cnet.com/8301-13746_7-57 ... oard-apps/) Would be brilliant to take care of music, calls (automatic pick-up and speaker phone mode, voice messaging and dialling etc.) safely while driving.
In essence, give waze the usability, utility, and the look and feel that would compete will paid Sat-Nav devices.
