Calm down: With a very few exceptions, America is no place for cyclists [via Economist]


DYING while cycling is three to five times more likely in America than in Denmark, Germany or the Netherlands. To understand why, consider the death of Michael Wang. He was pedalling home from work in Seattle on a sunny weekday afternoon in late July when, witnesses say, a brown SUV made a left turn, crunched into Wang and sped away.
The road where the 44-year-old father of two was hit is the busiest cycling corridor in Seattle, and it has clearly marked bicycle lanes. But the lanes are protected from motor vehicles by a line of white paint—a largely metaphorical barrier that many drivers ignore and police do not vigorously enforce. A few feet from the cycling lane traffic moves at speeds of between 30 miles per hour, the speed limit for arterials in Seattle, and 40 miles per hour, the speed at which many cars actually travel. This kind of speed kills. A pedestrian hit by a car moving at 30mph has a 45% chance of dying; at 40mph, the chance of death is 85%, according to Britain’s Department of Transport.
Had Mr Wang been commuting on a busy bike route in Amsterdam, Copenhagen or Berlin, his unprotected exposure to instruments of death—namely, any vehicle moving at 20mph or more—would be nearly nil. These cities have knitted together networks for everyday travel by bike. To start with, motor vehicles allowed near cyclists are subject to “traffic calming”. They must slow down to about 19mph, a speed that, in case of collision, kills less than 5%. Police strictly enforce these speed limits with hefty fines. Repeat offenders lose their licenses.
