Waze will probably always be separate. Your average mom and pop don't want Waze directions that take them down side streets, ask them to constantly make unprotected lefts, etc. They like the conventional routes and would probably get confused if prompted to select a route with one conventional option and one fast Waze option.
But I agree -- they need a turn by turn WAZE APP IMMEDIATELY! I bet they could even charge for it. The amount of time it's saved me driving around L.A. is worth at least $19.99
Waze is life. I just need to know where the Cops are when driving in the car pool lane by myself.
