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

lpg I think there are a lot of legally grey areas concerning cyclists/vehicles. Undertaking of any form is illegal, even if you are on a bicycle. This is where the 'grey area' comes in, is the .5m between a car and the curb a 'lane', in the strictly legal sense?

If there's a solid or dashed white line and a cyclist painted on the road between the line and the curb it is. If the line is solid, then all motor vehicles should stay out of it - if it's dashed, then it's 'advisory'.

But I still think it's the wrong place for a cyclist to be. Especially if the traffic is slow-moving or stationary.
