Not sure that every decision he has made has 100% been with Londoners interests at heart. The CC for example is a complete mess in every aspect apart from the fact it raises revenue.

I would agree though it is a case of damned if you do, damned if you dont to a great degree.
With regards to personal goals, he was quoted years ago saying he hates cars and would ban them if he could.
The introduction of the congestion zone was possibly a required thing to happen, but its all been done so badly its hard now to justify it, other than banning them as much as possible from London.

In a green view thats great, in a view taking society into account and social impact, its very different.
The idea to stage CC based on VED was poorly thought through, and VED and congestion could not be futher apart.
Let me get this straight, a London full of low and zero emissions cars would be an uncongested city? Nope, far from it.

So it went from being a sensible solution, to a financial penalty to the commuter and social driver..... AGAIN!

Based on that, I would say he took his personal hatred of cars too far.

Also the rephasing of traffic signals, the closure of the Blackwall Tunnel tidal flow (just before the planned consultation of Blackheath for CC expansion) and the almost deliberate poor road planning that we see all around London.

Just my opinion of course, and just one example of why I think Ken himself was becoming corrupt and distracted from the job in hand.
