Peak time is when the vast majority of people travel though. If that doesn't change, it feels a bit like tinkering around the edges.

You're right about the buses and passenger number, but I don't think they'll easily replace fast rail routes. I used to live in Forest Hill, which has the south circular running through it. I tried taking buses into the centre of town but it took ages, although I suppose you might be able to run "express" buses with fewer stops if there was more space on the road.

I just hope that whoever the mayor is during the next few administrations uses the ULEV to exponentially ratchet up the pressure on cars, so there's a breathing space that can be filled by public transport before people jump to electric cars and we end up with both cleaner air and less congested roads.
