A 6-minute mini-documentary tells the story of how the Dutch acquired their famous network of urban bicycle paths. Sequence of events:
1. Primarily pedestrian and bicycle traffic (early 1900s)
2. Booming economy = more cars + more sprawl + more roads = high pedestrian/cyclist fatality rate (middle 1900s)
3. Protests + Economic crisis = Bicycling returns (late 1900s)
