Wild Card's description 
Growing environmental problems such as noise and air pollution and increasing traffic chaos from a rising number of cars has led the European Union to enact a new law; European cities with more than 100.000 inhabitants have to completely close their inner cities for individual private cars. Only small mobility devices such as bicycles or scooters and all types of means of public transport, in-cluding electric vehicles from public car-sharing pools, are permitted in city centres. Private cars have to be parked in the periphery, e.g. in special car parks. The closure of city centres for private cars is obligatory and cannot be overridden by national policy.
