As autonomous vehicles and mobility systems scale, we must rethink how identity functions in an environment where human drivers are no longer the primary actors. Who is responsible when autonomy is in control? How do we establish trust, enable seamless interactions, and ensure compliance when decisions and transactions are made by AI-driven systems? This session will explore the critical role of identity in autonomous mobility, addressing how vehicles, users, organizations, and cities can be linked to accountable entities. We will examine how digital identity frameworks enable secure payments, access control, service authorization, and regulatory compliance—ensuring that autonomy operates within a trusted ecosystem. Real-world examples will highlight how mobility stakeholders are tackling these challenges today to enhance safety, efficiency, and user experience.
