Make Yahoo Maps detect driving motion. Have a setting that will remind you not to text and drive. Especially for those that are part of the AT&T "It Can Wait" Campain. Do this before Google Maps does something like it. When the setting is ON, if you start to text (for example on the iPhone) and Yahoo Maps has detected that you are moving along a road/highway, you should be prompted to "Stop Texting While Driving" (and exit texting program) or "Continue Because I Not Driving" (which will allow you to continue texting).
