Lorries in London, it'd be alright if cyclists just saw their point of view.

The over/undertaking thing is difficult. I was overtaking stationary traffic on Clerkenwell on the right, and a guy almost hit me doing a u-turn without indicating. there was a turning to the left and no turning to the right, so i was going at a reasonable clip, thinking that i was okay. fortunately it was dry, or i'd have gone over the bonnet.

a policeman saw the whole thing, and pulled me over to the kerb and gave me a lecture about being careful!

The copper should have given the car a lecture, and a much stiffer one, too. He was driving without due care.

In general, however, if you are over-taking on either side, you have to prepared for people pulling across your line without looking (including peds). That's why I prefer to be on the right. You have more space, and can get right across and give yourself a wider field of vision.
