All that remains of the garden city in our own day are traffic-free enclaves, islands in a sea of traffic where the pedestrian leads a legally protected by languishing existence, comparable to that of the North American Indians on their reservations...In reality the modern urbanist regards the city as a gigantic centre of production, geared to the efficient transport of workers and goods, to the accommodation of people and the storage of wares, to industrial and commercial activity. The rest, that is to say creativity, life, is optional and comes under the heading of recreation and leisure activities.
