Directly – Serco. Indirectly – TfL, who need to keep up the pressure on these jokers. Things improved hugely last summer after TfL issued their critical improvement plan (sp?). Now things have slipped badly.
And Ozzage, your point is related – there would have been spaces if Serco was redistributing properly.
Ldnfatso – that’s totally unacceptable. I had a go at TfL a few weeks ago for not picking up red lighted bikes. They seemed to imply they wait for a certain number of red lights in each neighbourhood before picking them up (i.e. there’s no time limit).
