In order to achieve the goals of a lesser dependence on the automobile in daily life (access to schools, to public transportation, to neighborhood stores) and to create a more diversified real estate market, it is necessary to oppose the reticulate 'walking city', made of a hierarchy of thoroughfares connected to the existing streets, to the 'franchised city' as it is emerging today with the multiplication of secure zones. The latter cannot be opposed solely with an ideological argument about the damaging effects of community withdrawal or by the denunciation of the illusions of an approach based exclusively on security. Experience indicates that it is necessary to convince the elected officials, the voters, the users and the professionals that organized enclaves - that are not limited to residential spaces such as gated communities - have direct consequences on the life of the city since they impose lengthy bypass routes in order to reach daily services.
