Abstract: A device, method, and system may remotely monitor one or more subsystems in a terrestrial vehicle. In one embodiment, a method and system may schedule maintenance and order replacement parts after comparing the reported data with threshold data. In one embodiment, stake-holders, law enforcement entities, government agencies, and national security organizations may access the reported data. In one embodiment, a modular device may monitor vehicle subsystems, vehicle environmental data, a driver's heart beat, a driver's eye activity, a driver's head position, vehicle environmental data, and a driver's ID data.
