I have spent the better part of forty years negotiating traffic, mostly London's, and over thirty years professionally. During the nineties, the volume of traffic in sheer numbers remained static, yet during that time congestion increased greatly. The cause; bus lanes, cycle lanes, narrowing of roadways through pavement build-outs, increases in the number of traffic lights, re-phasing of existing lights to stay red longer, road bollards, chicanes, speed humps, cutting off short cuts by revising one-way systems through back streets, and paving over large areas previously tarmac - Trafalgar Square being just one diabolical example of restrictive - destructive engineering. This was the precursor to the introduction of the Congestion Charge, Upon that day in February 2003, all previously long established 'Road Works' along with severe restrictions along Victoria Embankment due to the construction of the new footbridge across the Thames at Hungerford, were swept away as if by magic. Voila! Congestion Charge worked! Set up, and stitched up - that's the story of London's drivers. Tournique'd into submission - along with Livingstone's claims of "Londoner's want it - If they don't, we'll remove it". Lying git.
This has been out a couple of years - well worth a watch: http://www.maniacfilms.com/maniac/media ... ds2009.mov
