Mobility is on the move. Due to symptoms of the socio-ecological crisis, present mobility systems are increasingly questioned and contested all around the world. In this context, this special issue aims to illuminate the role that socioculture plays in mobility transitions, thereby interrogating technocentric views on mobility transitions. It focuses on the following overall questions: How is future mobility portrayed and constructed in current discourses? What role do or can different kinds of actors play in transitions toward sustainable mobility systems? How are urban mobility cultures changing? What kinds of new practices and mobility patterns emerge? Do future mobilities re-enforce existing sociotechnical regimes and social inequities or create new ones?
