"Oh Shit" moments...

only to find that one of the cabs I had been trying to get distance between had only just overtaken me and made a last minute left turn at Drury lane - and stopped right in my path.

I fucking hate it that so many drivers seem to think this is acceptable, speeding up to overtake and get ahead just so they can turn right in front of you. I heard an Addison Lee driver lost his wing mirror shortly after a maneouvre like that near Waterloo bridge once.

Did you get an apology from the cabbie?

Was your bike alright? Sounds like it's his to sort out if it's not, even if you were technically behind him, if he cut you up there's not a lot you could have done.
