HERE is a great Guardian Focus podcast on cycling in the UK. Part of the great Bike Podcast they do.
With the caveat that I do not live or cycle in London, I agree with some of the things discussed but disagree with others. Not enough is invested in cycling especially considering the economic benefits of cycling and the billions lost every year because of congestion. I think they have been too harsh on Boris Johnson - although it is not perfect, plenty of progress seems to have been made in London on cycling. A lot more needs to be done though. London's Blue Lanes are clearly insufficient but I disagree that they do nothing - I think that they are likely to raise awareness and change attitudes slowly. I am concerned however at the lack of resources used for cycling when funds are found for other transport. I was interested to discover that Tony Blair revealed in his memoirs that the closest any of his governments came to collapse was when there were queues at the petrol pump (I have not read it). It shows the power of the car lobby. I was happy to see that petrol prices in the UK are probably now about two thirds to three quarters of the full cost of humanity. They still need to rise further.
