(2) - The official tourist guide for Dublin City shows 64 outdoor photographs.  If we count the vehicles shown there are: 10 boats, 3 buses, 2 trams, 2 trains, 2 horses, 0 cars.  If you were to take this at face value, you would believe that Dublin was a carfree city with the charm of Venice; prospective tourists know there will be cars in the city but somehow they block it from their minds.
