This book is a small contribution to discussions on mobility, bringing to light elements that, at various times, whether in academic circles or in urban planning, are considered "adjacencies" of the individual modal and the speed imposed by modernity. In addition, the content of the essays emphasises the importance of planning with human beings in mind, the social individuals who share the same space of coexistence and sociability. Finally, the reading may seem uncomfortable at first, especially as it is an essay, with characteristics that can easily be confused with aphorism, but within this apparent chaos and disconnection there are small threads tangled like networks that invite us to think about how such "adjacencies" are much more than just accessories for individuals and individual transport and that encourage us to think about the immense heterogeneity found in the urban environment and that should not fail to be part of planning, nor of the attitudes of any city dweller.
