My worst experience as a cyclist when I was 16 where white van 'sandwiched me between the side of his van and a row of parked cars, so I agree with the new rule that cyclists should give themselves far more clearance so if an idiot in a white van tries to overtake too close, there is room to manoeuvre on the left hand side.

The only plus was that I got away with miniscule damage to myself and my bike, but the car I was sandwiched against had a dent along the whole of its right hand side, and was possibly written off by its insurer, as the van did not stop, and therefore its insurers culd not be held liable.

here is also a good animation that simply explains the turn left rule - pedestrians and cycles going straight on at the junction have priority to cycles and motor vehicles turning. End off.
