The LSE have produced an interesting report: http://eprints.lse.ac.uk/38063/1/BritishCyclingEconomy.pdf
I had a good idea for a spoof, like those videos you see of people doing their own driving/ riding commentary but of an 'advanced pedestrian' with a shoulder mounted gopro navigating busy streets of head down phone gazers using a safe system of walking - 'Pavecraft'. In my head its really funny.
Some phone gazer or shop window stopper, giving it the Ronnie Pickering. Or maybe do a straight comparison of annoying walkers and annoying cyclists. The cyclists must have gotten annoyed at crap walkers before so maybe it'll be like a light bulb moment for them, that their hobby is as annoying as a walker who 'tacks' across the pavement like a yacht.
