A communications system for land vehicles usable in the field of radio communications with any electronic data processing equipment connected to a mobile telecommunications network. The cover rotates 360 degrees with respect to the bottom portion. The method and system of the invention allows a simulation developer to create \u201cmulti-path\u201d simulations more quickly and efficiently by, for example, recognizing which junctions in the simulation are starting points for multiple paths, where the multiple paths converge, and the content of the multiple paths. This process is repeated a second, later time, for the same human, and the same process is completed for the subsequently-acquired voice information.
