Cities are full of fear, which is partly why and partly because people move in cars.
– Dave Horton, Fear of Cycling
There is no terror in the bang, only the anticipation of it.
– Alfred Hitchcock
Plantary Gears ruminates on a few points from Horton's essay about fear of cycling, including this...
Until the 1920s-30s or thereabouts, streets served as a conduit of traffic, but also as an unstructured social area, children's play area, etc. As more people started driving cars, it became clear that the streets could either remain multipurpose social/transportation spaces, or they could be dedicated to the efficient flow of automobile traffic, but not both. Obviously the trend was, and continues to be toward permitting the cars to be driven unfettered, and effectively, if not legally, prohibiting the activities of people who aren't in cars.
And then drifts into a discussion, which continues in the comments, about the need of certain people to segment themselves into evermore specialized subcultures.
Not for cyclists only.
