The document discusses the design of a shared mobility system called the Reconfigurable Share Use Mobility System (RSMS). The RSMS is intended to be modular, integrated, customizable, convertible, and scalable like Lego pieces. It aims to evolve beyond traditional car ownership models to meet the needs of millennials who favor access over ownership and are more connected, have less income, and are delaying major financial commitments. The design underwent several iterations before culminating in a final computer-aided design of a modular vehicle with considerations for its braking system, opening mechanism, and structural integrity.
