Abstract
There is a linear relationship between ownership and the use of motorvehicles, which is only disturbed by retarding influences from measures taken by the government or economic recessions. Therefore, the recent sudden traffic-growth must be seen as merely catching up with the old trend. Restrictions of car-use by government measures or by an economic recession would seem likely in the near future, making it doubtful that 8 million cars will have been reached in the year 2010.
