Immanuel Kant was a real pissant who was very rarely stable on his cycle.

As we contemplate the construction of a billion-dollar monorail leading from the vicinity of Bicentennial Park, up the escarpment to CM CeeSaw's home in Silver Hills, ethical aspects of bicycling and transportation are discussed.

If Kant Were a New York Cyclist, by Randy Cohen (New York Times)

... If my rule-breaking is ethical and safe (and Idaho-legal), why does it annoy anyone? Perhaps it is because we humans are not good at weighing the dangers we face. If we were, we’d realize that bicycles are a tiny threat; it is cars and trucks that menace us. In the last quarter of 2011, bicyclists in New York City killed no pedestrians and injured 26. During the same period, drivers killed 43 pedestrians and injured 3,607.

Cars also harm us insidiously, in slow motion. Auto emissions exacerbate respiratory problems, erode the facades of buildings, abet global warming. To keep the oil flowing, we make dubious foreign policy decisions. Cars promote sprawl and discourage walking, contributing to obesity and other health problems. And then there’s the noise.

Much of this creeping devastation is legal; little of it is ethical, at least where, as in Manhattan, there are real alternatives to the private car. But because we’ve so long let cars dominate city life, we take them, and their baleful effects, for granted. The surge in cycling is a recent phenomenon: we’re alert to its vagaries.
