At Stockwell lights I'd say I was in a crowd of about 20 odd cyclists (and one sad moped man). Lights change and we all shoot off - like a random swarm of bees - up towards the Oval tube - undertaking, overtaking, some indicating, some not, some dawdling, some sprinting. I thought, somebody goes down a lot of people will get hurt.
I was thinking, as I approached the Oval - that perhaps some basic cycling code should be made available? But I guess that's something that just comes with experience as one does not want to be too formal about this. And no doubt other cyclists were thinking the same about me as well - he doesn't know what he's doing.
But the long drag up to the Imperial war Museum was good - long, empty bus lane, only two other cyclists and able to really give it some.
