Tube strike, London

I wrote a long reply to it but then gotted logged out and it disappeared as I clicked Submit.

Bottom line - yes I did, and I was still expecting him to ease off the accelerator just a bit. I'm too lazy to re-type the reasoning, but it was pretty much "Cars are disadvantaged in Central London. Bikers own the roads" just not as strict.

My point is - he will sit in traffic in 20 seconds time - give me space to move on at my pace cause I won't

What? I'm not sure what reasoning you used to come to that conclusion, but I don't see how that disadvantage will make itself obvious if/when said coach/bus/HGV doesn't see you and veer left.

What part of not undertaking is difficult to understand. Unless you know for sure everything is stationary for an extended amount of time. Don't do it.

You ever see someone get wedged by undertaking even at 10mph? It ain't fucking nice.
