Reached destination status. Value returned when provided GPS location gets within 7-40 meters, along the route, of the next destination. Once within 40 meters of the next destination the vehicle is tracked to determine if it is getting closer or moving away from the next destination. If the vehicle continues to get closer this value will be returned when within 7 meter of the next destination, if the vehicle starts to move away this value is returned. This status can be used to automatically call RouteTracker.switchToNextDestination().
