Undertaking / filtering on left?

Tower Bridge is bad for this. I had a chat with a driver that stated "we're all over the place. YOu're on the left and the right."

Which causes even more frustration with those that have the requisite speed and skill that still dwell in ignorance and opt to undertake- normalising (sometimes) bedwetting behaviour.

Peoples mindset is so messed up sometimes, they pick on something and use it for ammo regardless of whether its relevant. I'm over it now, I ride in a manner that I don't die and just ignore what people are saying in their tin cans.
