An exemplary method of manufacturing a polymer matrix composite electromagnetic shielding structure includes pretreating a dry fiber reinforcement with a composition including a carrier and a conductive element, laying out the pretreated reinforcement to form a pre-form structure, applying a resin to the pre-form structure, and curing the resin at room temperature. The game is operable for a first play and a second play. The central server obtains location information or geo-related information pertinent to the route taken by the automobile, filters the data according to certain criteria, and then delivers an audible version of the filtered data to an audio output device such as a radio receiver located in the automobile.
