Note the figure at the top of this canal bridge, which is at the edge of The Vondel Park in Amsterdam. Such "road art" can be difficult to see from a car; it's there largely for the bike riding public.
Would such a figure be admired or resented in California? Would it be considered graffiti--and removed by road crews? Would the artist be subject to arrest?
Note too, the complete lack of any safety gear on these bicycle commuters. Once again, is that the price we should pay to make the bicycle part of our daily lives? Yes, our emergency rooms would end up with more business--in the short term. But in the long term, we would have fewer fatties and thus fewer heart attacks and strokes.
