Is it allowed?

Many customers have asked, is it possible to use Google free API for applications like SeeMe launched lately. The answer is: NO, IT'S NOT ALLOWED! License says: "Except where you have been specifically licensed to do so by Google, you may not use Google Maps with any products, systems, or applications installed or otherwise connected to or in communication with vehicles, capable of vehicle navigation, positioning, dispatch, real time route guidance, fleet management or similar applications".

…Service may not be used: (a) for or with real time route guidance (including without limitation, turn-by-turn route guidance and other routing that is enabled through the use of a sensor), or (b) for, or in connection with, any systems or functions for automatic or autonomous control of vehicle behavior.
