Just thinking if Ken had acutally done anything more with the bike idea than let someone suggest it shortly before losing the election, then it wouldn't exist. Barclays wouldn't have sponsored it. I'm not sure the boroughs would have played ball either with the docking stations either. And as Ken hated bikes there would be no cycle superhighways. And then what public funding there was for the scheme would have been given to Lee Jasper who would then have embezzled it.
On the plus side if it had gone ahead the bikes would be red, which is faster and more Londony.

FYI, both policies were formulated by the Commissioner's Policy Unit at TfL in late 2007 and presented to the public in February 2008.

The current Mayor kept two of the policies suggested then, with reduced funding, and has spent virtually no money on the third, most important one ('Biking Boroughs', called 'bike zones' in that article).

Installing the docking stations is simply a matter of obtaining planning permission from the local planning authority. You're probably right that the City of Westminster in particular would have been much harder to convince to give permission, but ultimately planning decisions are subject to planning guidance.
