"The problem of rising demands for mobility versus the need to reduce the CO2 emissions from car traffic makes mass motoring, on a global scale extended to all peoples, an impracticability. Will the nations of the world, sometime around the year 2025, have to reach an international agreement on mandatory quotas of public transportation, to decrease the number of engines? The paper discusses a systems approach as a base to deal with this "glocal" dilemma. One solution might be to give urban networks in intermediate regions a greater role to play in future. If so, ecologically sound and versatile vehicle systems must be developed for these regions around the world - within a dialogue between "North" and "South". Such a perspective also opens up new opportunities to obtain more sustainability in the urban structures and the already built environment. This could have an important social and cultural impact on regional welfare and the economy: regional urban networks can develop into attractive sustainable societies."
