Is it really true that cycling is safer than driving? I mean, we all know the statistics about how many more cars are on the road, but what about the relative risk per mile traveled? Are we just trading one set of risks for another? Are the safety benefits of cycling mostly due to the fact that were not surrounded by a ton of metal, or is there something more fundamental at play? And dont even get me started on the whole safety in numbers thing - is that just a myth, or is there actual science backing it up? Ive heard arguments that cycling is safer because were more alert and attentive, but isnt that just a selection bias? I mean, whos more likely to take up cycling in the first place - the careful, defensive types, or the thrill-seekers? What are we really comparing when we say cycling is safer? Are we comparing apples to apples, or are we just cherry-picking the data to make ourselves feel better?
