Traffic levels have fallen by 15% and congestion is down by a third. In August the Mayor of London announced a plan to extend the 5 charge for driving in central London during the working week westwards to Kensington and Chelsea. This was despite a consultative process in which almost 70,000 people and the vast majority of respondents said they did not want the scheme extended. However, the problem with the proposed extension is not only political. Extending the zone to a thickly populated area of London will mean that many people will qualify for the residents discount, allowing them to drive to the city without paying any extra. Extending the scheme therefore may mean that total revenues drop from the current 90 million a year.
