From The Daily Mail:
Oxford Street will be pedestrianised by 2020, the Mayor of London's office has announced.
The plan is part of new mayor Sadiq Khan's commitment to tackle air pollution in the England's capital city.
Cars are already banned on most of Oxford Street between 7am and 7pm on every day apart from Sunday, but it is a major thoroughfare for buses and taxis.
I'm a big fan of pedestrian precincts and it's quicker walking or taking the Tube than taking the 'bus in central London anywyay, but assuming that buses are currently taking the shortest/least slow route from A to B via Oxford St, won't diverting them via a different route just cause more air pollution, not less? So is this just a meaningless political gesture or does it actually make sense?
