This is a series of posts discussing the practical issues of cycling infrastructure. It raises issues that a lot of communities overlook--how a few bike-hostile bottlenecks can make an entire area too difficult to commute by bicycle, why sandwiching small bike lanes between motor traffic and parked cars is an unsafe and impractical solution, and how existing infrastructure is biased to the interests of motorists to the exclusion of even considering bicycles as a valid transportation method.
