This evening, while cycling south on City Road riding primary at about 25mph, I go to change lanes into the bus lane and very nearly come off my bike... going over the bus lane road marking. A taxi was right up my arse too and I would've been straight under it, but I somehow managed to regain traction and balance. Lifted the heartrate somewhat I tells ya.
Was after a bit of rain, over a recently painted line marking (in my view too thick), hitting it at a low angle and on fully pumped up gator hardshells.
Reminded me of how easily accidents can happen, it's such a common manoeuvre you wouldn't think twice about it.
