A common political argument is that bike and transit riders should “pay their own way.” A study in Vancouver however suggested that for every dollar we individually spend on walking, society pays just 1 cent. For biking, it’s eight cents, and for bus-riding, $1.50. But for every personal dollar spent driving, society pays a whopping $9.20! Such math makes clear where the big subsidies are, without even starting to count the broader environmental, economic, spatial and quality-of-life consequences of our movement choices. The less people need to drive in our cities, the less we all pay, in more ways than one.
Another study in Copenhagen (where the full cost of transportation choices are routinely calculated) found that when you factor in costs like time, accidents, pollution and climate change, each kilometre cycled actually gains society 18 cents!
