Well, the standard of cycling has hit rock bottom along Oxford Road in Manchester...OMG - students are back. Add students wobbling on bikes, road works and lots of busses, I am really surprised non of them have been run over yet. You get riders who actually don't know what's happening arround them, and wobble off in front of busses in their own world, to those that are jumping red lights, scattering folk, on-off pavements......
As for ASL's - depends upon traffic, how easy it is to get to it, or if it's actually better to hang back and stick with the traffic flow.
