As it has been noted, the one primary problem is with data. The other is with deciphering user conventions in referring to that data. The Nokia maps app for iOS knows where the nearest supermarket is to me, but still refers to it as "Albertson's."

When human beings give directions, they can use information from the other party to improve their directions. How is this done with maps apps currently? I guess turn-by-turn apps can detect when someone deviates from the directions and use this data as feedback.

I wonder how much a maps/navigation app would benefit from being able to detect exclamations of anger? Or, even simpler, what if there was a "WRONG!" button positioned right where someone could press it on impulse? Or let users violently shake the device to let the server know they're mad? (Maybe activate a sound recording of their complaint for that 10 second timespan?)
