General questions/observations/discussion

So anyway, following on from my largely unreceived previous question, here's another instance of me interacting with a fellow cyclist:

• waiting in queue at lights on Clerkenwell Rd (west side), waiting to cross Farringdon Rd and head up Clerkenwell Rd (east side). There's the usual queue of cyclists who've filtered up the inside, but I've chosen to sit in the middle of the lane, behind a black cab.

• lights change, I set off, matching the speed of the motorised vehicles in front of me. I'm watching both this stream, and the stream of cyclists further over towards the kerb.

• in my mind, I'm prepared to either follow the motorised traffic as it passes slower moving cyclists, or filter back to the left in order to join the stream of cyclists; which decision to make should become obvious by the time I pass the Clerkenwell Green junction on the left.

• motorised traffic suddenly ups the pace more than I'm inclined to, so I prepare to filter to the left.

• at this point, another cyclist comes past me -CLOSELY- on the inside, before proceeding to squeeze between the line of bikes and the line of cars. I'm not happy. Thankfully I did a quick glance to my left before moving.

• catch up at next lights; I get his attention, and he takes an earphone out (*disclaimer: I'm not against earphone use on a bike *per se**).

"You shouldn't undertake other road users like that."
"You were in the middle of the road."
"I was in the middle of the lane, and about to move left. You should've swung out and overtaken me."
"You were in the middle of the road. I'm not going to ride on the wrong side of the road to get round you."
"I was in the middle of the lane. You had half a lane in which to pass me. Don't undertake, it's dangerous."
"You were in the middle of the road."
"Whatever."

Stupid arrogant dangerous prick :-|
