Abstract: An apparatus and system for: combining independent driving vehicles into a single assembly for condensed, efficient, variable capacity transportation on common routes; and for separating into independent vehicles for flexibility on diverse routes. Connection logistics are exchanged locally via line of sight optical channel. Retractable coupling and mated coupling on opposing ends of the vehicles provide multiple degrees of freedom (DOF) to accommodate misalignment during initial dynamic engagement, and lock as rigidly coupled assembly with zero DOF. Mating vehicles' doors open during transit, permitting inter-vehicle movement and consolidation of passengers en route to urban locales, and release of empty vehicles. On return, independent vehicles combine to dense passenger vehicles from urban locales for redistribution of passengers in individual vehicles that later separate for diverse destinations.
