Original sentence: " Ordinary cycling is not demonstrably more dangerous than walking or driving, yet no country promotes helmets for either of these modes."The inherent risks of road cycling are trivial... Six times as many pedestrians as cyclists are killed by motor traffic, yet travel surveys show annual mileage walked is only five times that cycled; a mile of walking must be more "dangerous" than a mile of cycling..." The proportion of cyclist injuries which are head injuries is essentially the same as the proportion for pedestrians at 30.0 % vs.44,000 cyclists were reported injured in traffic crashes in 2006.92% (720) of them died in crashes with motor vehicles.A UK opponent of compulsion has pointed out that it "still takes at least 8000 years of average cycling to produce one clinically severe head injury and 22,000 years for one death.About 540,000 bicyclists visit emergency rooms with injuries every year.Bicycle crashes and injuries are under-reported, since the majority are not serious enough for emergency room visits.In a campaign to make helmets compulsory for child cyclists, it has been stated that "in a three-year period from 2003, 17,786 children aged 14 and under were admitted to NHS hospitals in England because of injuries incurred while cycling".Of those, about 67,000 have head injuries, and 27,000 have injuries serious enough to be hospitalized.One pro-helmet website gives its "own pick of Basic Numbers from many sources": 773 bicyclists died on US roads in 2006, down just 11 from the year before.Proponents of helmet compulsion may tend to quote figures for the (large) total number of head injuries or injuries of any kind, opponents may be more likely to produce estimates for the (low) risk of serious injury per cyclist.There is no one agreed way of presenting risk which would allow everyone to agree an answer to this question
Edited sentence: Detailed analysis of hospital admissions data also fails to support the idea that cycling is unusually dangerous: a study in the UK found that the proportion of cyclist injuries which are head injuries is essentially the same as the proportion for pedestrians at 30.0 % vs.Ordinary cycling is not demonstrably more dangerous than walking or driving, yet no country promotes helmets for either of these modes (although there was an experiment in Japan with walking helmets for children, which demonstrated no measurable benefit)
