If TFL want people out of their cars, then they have to improve public transport in Southeast London. A good start would be a bike parking facility, like the one at Finsbury Park, in Brixton. Also Southwark need to work with them to extend Boris bikes. Of course, extending the tube into SE London would be best, but it appears that new lines are now entirely contingent on being able to direct public money in a way that subsidises the profits of 'luxury' housing developers.
