Sadiq Khan pledged to help cyclists – so why is he such a stick in the wheel?

Subverting superhighways with sorry quietways; preserving motor vehicle capacity even if it brings conflict with cyclists - the mayor must do better

Do you remember that Blackadder scene where General Melchett proudly unveils a map representing the territory gained by his troops? Dimensions: 17 sq ft. Scale: actual size. London mayor Sadiq Khan's cycling programme - formerly Britain's bike flagship - is starting to feel a bit like that.

More than a year since he took office pledging to "make London a byword for cycling", "accelerate" the existing programme and "triple" to 36 miles the length of segregated cycle superhighways, the mayor has by my count built and opened 80m (260 ft) of new segregated lane. Work is progressing, extremely slowly, on another half-mile or so. And that is about it.
