Core Viewpoint - The incident involving the Xiaomi SU7 highlights significant safety concerns regarding the design of car door handles, particularly the lack of mechanical redundancy in emergency situations [2][3][5]. Design Issues - The Xiaomi SU7 features a hidden door handle design without a mechanical external handle, making it difficult for external rescuers to open the door in emergencies [3][4]. - The internal emergency handle, while present, may not be accessible to occupants who have lost consciousness after a severe impact, limiting its effectiveness [3][5]. Industry Standards and Responses - The automotive industry typically incorporates mechanical redundancy in hidden door handle designs to ensure safety during power failures, as seen in models like the Volkswagen ID.4 and GAC's models [4]. - Recent regulatory proposals emphasize the need for mechanical door handles to ensure safety in case of electrical failures or accidents, mandating that each door must have a mechanical release option [7][8]. Cost Implications - Transitioning from hidden door handles to traditional mechanical designs involves significant costs, including redesigning electrical systems and molds, which may deter manufacturers from making changes [8][9]. - The automotive industry is currently evaluating how to balance safety requirements with design aesthetics and cost considerations, as many manufacturers have invested in hidden handle designs [8][9].
