A survey conducted in Rome in July by the Osservatore sulla mobilit found that of the 286,813 vehicles coming daily into the centre of the city, an area which is restricted to permit holding vehicles, 51 per cent were motorcycles or miniature city cars, which do not require a permit to enter. When these figures were released the city councillor responsible for the movement of traffic suggested that the time had come for the creation of special traffic lanes exclusively for two-wheeled vehicles. It is estimated that there are 600,000 motorcycles, scooters, and mopeds in Rome.
