With cars - The suburb ceased to be a neighbourhood unit

As soon as the motorcar became common, the pedestrian scale of the railroad neighbourhoods disappeared, and with it, most of its individuality and charm. The suburb ceased to be a neighbourhood unit: it became a suffused low density mass. But the motorcar had done something more than destroy the pedestrian scale, it either doubled the number of cars needed per family, or it turned the suburban wife into a full time chauffeur.
