Cycle campaigning

Just found the short the above image reminds me of, if you haven't seen this short documentary on Dutch cycling infrastructure, I do suggest you go here.

To summarise:

Changes occurred to Dutch transport polices due to:

1. Cities steadily grew more and more unable to cope with the increase in road traffic.
   
2. Public outrage grew at space given to motorised traffic.
   
3. The intolerable and ever-increasing amount of road traffic deaths lead to mass public protests under the banner of "Stop Der Kindermord" ("Stop the child murder).
   
4. An ongoing oil and economic crisis leading to gas shortages and high prices for energy.
   
   

Solution:
A political will on both national and municipal level with decision makers and planners working together to deal with the situation, leading to the turning away for car centric policies and making way for alternative transports, such as cycling.

How much of the above can be applied to London and the UK?
