Another interesting fact is Cologne and Amsterdam is they are bicycle cities. Bicycles ad their riders have the right of way on the sidewalk, and have their own street lights. The intersections have a light for the cars, the pedestrians, and the bicyclists. Gasoline is $6-10 per gallon. So I can see why bicycles are popular.
Roads and highways are narrow. If our bus window could be opened, I would be able to touch the passing vehicle. Glad the driver knew how to maneuver.
