  • processing of the stream of messages, by an alert processor coupled to the internal digital communication system and configured to snoop on the stream of messages on the internal digital communication system, to characterize a current state of the vehicle based on the stream of messages;

    processing by the alert processor of the current vehicle state to determine whether the current vehicle state corresponds to an alert condition, the alert condition being a member of a stored set of pre-defined vehicle states; and

    in the event that the current vehicle state does correspond to the alert condition, causing by the alert processor generation of an external audio alert corresponding to the alert condition.
