I'd simply be interested to know (as opposed to "invent") how much of the OP is true and how much is embellished. And how much is down to a driver misinterpreting the actions of the cyclists and how much to the cyclists behaving like supercillious arses. As I said, not having seen the incident in question I don't know any of these things, so comment seems a bit pointless.
Well, RT, I know the road very, very well and know that the OP's friend must have been talking bollix (or exaggerrating if you prefer) as I pointed out earlier. I hope this post isn't deemed as pointless as everyone elses'
