I never learned to ride a bicycle. And yet I am an active member of an organization dominated by bicycle riders, and is often focused on increasing the number of urban bike lanes. Why?
Because I believe that walkers benefit from bike lanes as well. Here’s why: when a traffic lane is devoted to bicycles and taken away from cars, this means that the remaining lanes are either narrower or there are fewer of them. As a matter of common sense, it seems obvious that motorists drive more slowly on narrower streets. And when motorists drive more slowly, they are less dangerous to walkers or to each other.
