System confluence and the reinvention of automobility

The aim of the paper is to provide a longitudinal account of the emergence and stabilization of the automobility system and to assess the contemporary state of the system in the early stages of an ongoing sustainability transition. The production, use, and disposal of cars, in a pervasive global automobility system, are examined to reveal and explain the growing sustainability significance of overlaps with other systems. System-to-system confluence to varying degrees is ongoing with electricity, housing, aerospace, and information, software, and communications systems. The interfaces between multiple systems are evidenced by contestation for legitimacy via technological innovation and organizational experimentation. The result is uncertainty among key actors and stakeholders, institutional reforms, diverse corporate strategies, and emergent societal practices and behaviors. The paper thereby provides a contextualized account of the tension between barriers to change that may preserve the coherence of the automobility system and differential boundary effects arising from the impact of other production-consumption systems that may result in regime fragmentation. Confluence with other systems may resolve some sustainability contradictions but will also create new ones. Appeal to sustainability science will be key to evaluating how far existing sustainability problems will be resolved, and how far new ones will emerge in the automobility transition.
