A reconfigurable transport vehicle and method are presented, wherein multiple independently operable vehicles are selectively coupled to form a structurally integrated multi-unit assembly. Each vehicle includes a passenger cabin defined by structural side panels incorporating retractable partitions. Upon mechanical coupling of adjacent vehicles, the partitions are configured to retract into the vehicle body, thereby forming a continuous, unobstructed interior cabin space extending across the coupled vehicles. The system further includes a control mechanism configured to coordinate the motion of the coupled vehicles such that the assembly operates as a single kinematic unit. Coordinated steering is achieved through position-dependent control, in which vehicles at different locations within the assembly adopt different steering angles to maintain rigid-body motion during turns. The disclosed configuration enables transformation from independent single-unit operation to a unified multi-unit vehicle with expanded interior space, without reliance on fixed infrastructure. The invention provides improved spatial continuity, structural integration, and maneuverability compared to conventional modular or platoon-based vehicle systems.
