This article is a reflection on two levels of the ‘political’ in which the æsthetical dimensions of mobility infrastructure play a key role. Informed by the empirical analysis of mobility infrastructure recent evolution in Brussels-Capital Region, it highlights on one hand how, at the level of the ‘infra-politics’ of mobility, the sensory accelerating and decelerating dispositifs constrain the potential sensory-motor ways of being as much as regulatory and material ones. On the other hand, it reveals the potential of mobility infrastructure as sensitive environment to sustain, through the resonance between infrastructure, environment, vehicles and bodies, an increasing ambient sensibility that nourishes the political engagement of mobile actors toward a sustainable future.
