Mobility is essential in improving the quality of life and access to the city's opportunities. However, it contributes to and is affected by planetary emergencies, such as environmental and health crises. Therefore, cities must address their spatial organisation, technology, and a better understanding of the societal construction and regulation of urban mobility behaviour to reduce emissions, promote healthier environments and mitigate climate challenges on time. Three global metropolises offer contrasting realities. Tokyo, Paris, and Buenos Aires have specific urbanisation patterns in space, demographics, cultural attitudes, socioeconomic situations, and institutional organisation. But they are all affected by global cycles and health crises, like the last pandemic, from which some common lessons should be learnt. As a result, there could be a greener, more socially inclusive, and more intelligent urban development. Of course, an acceleration of change can create conflicts in the short term. But a multidisciplinary approach to achieve an adequate difference in space design and management behaviours, and-beyond the scope of this paper-the adoption of new technologies, could offer an achievable roadmap for a different social organisation of urban mobility.
