Cycling and Risk Taking survey

This point worries me, as it seems to imply that these sharp turns are the most dangerous ones, and i'm not convinced.

Imagine a lorry going along a straight road a reasonable distance from the kerb then around a corner and onto another straight section, ending up again at a reasonable distance from the kerb. Follow the curve traced by the rear wheels. For the gap between the lorry's wheels and the kerb to close, the wheels have to follow a *gentler *curve than the kerb *. But pulling out to the right first allows lorries to turn their rear wheels *sharply *around corners. It's when the lorry *doesn't *pull right first that the gap closes without warning. .... etc.

In most of the fatal crashes the cyclist is hit by the very front corner of the left turning lorry. On most streets pulling over to the right before turning left is the only way to get a large lorry around the corner, it is not a question of speed. Very few cyclists realise how far to the right large lorries need to be, often it is around 3 metres from the curb. The lorry will beging by going straight ahead, it doesn't seem to be turning at all, then it will turn in very quickly catching the cyclist by surprise, knocking them down and running them over.
It is not the lorry you have to squeeze beside which is dangerous, it is the one that has moved to the right leaving a very large gap.
