I'm not sure if DOTD in this case was myself, the other cyclist, both or neither, but in any case, a faintly amusing and vaguely interesting incident. I came to a T junction with a hill. I wanted to turn right, down the hill. I couldn't see what might be coming up the hill because of a tall van parked on the corner, so I did (most of) what you're meant to do: stopped, looked both ways, then pulled out a short way so I could see round the van, stopped again. Except actually I forgot to do the shoulder check you're meant to do before moving, so that's one dick point to me. Having pulled forward in this way, I could now see a a cyclist coming up the hill, just alongside the parked van, with a car behind him. So I waited. The cyclist turned sharp left as soon as he'd cleared the van, looking as if he as going to enter the side street I'd just pulled out of. But no, he rode over the white lines behind me then pulled out round the next parked car and carried up on the hill. Meanwhile the car had overtaken. I'm not sure if he did this deliberately to let the car overtake or what.
