Centralised discussion space for TfL plans and cycling in London

Being arrogant, negligent, and lazy might be required to force through change in London where a more conscientious individual would get derailed by consultation and consensus.

No, it only creates lingering resentment and the reaction won't be long in coming (as Trump will find out). Just look at Livingstone and the Western extension. That's not to say that transport policies generally happen through 'consultation and consensus'; rather, they're prepared for years mostly in secret/when nobody's paying attention and then pushed through at convenient times without much involvement by the public. See Silvertown Tunnel, the most recent example.
