Of course. Why are you surprised? As a rusty statistician, I can confirm that the decrease was quite insignificant, and I stand by my previous posting. I should also point out that such unpredictable factors as weather are known to have quite large effects on road casualty statistics, so anyone claiming that statistical significance of a single period implies a change in the incidence is, at best, misguided. As all trolls are, of course. Regards, Nick Maclaren.

In a few cases that is the problem, often encouraged by the provision of a cycle lane into an ASL on the left of the road. But it's more often the lorry pulling up alongside the cyclist. It also doesn't happen very much with buses or coaches where one would expect a similar problem. Its only with lorries which represent about 1% of the traffic on the roads of London and ~50% of the cyclist fatalities. That also tends to indicate its something about the lorries and their drivers, not the cyclists. -- Tony " I would never die for my beliefs because I might be wrong." Bertrand Russell

Probably cycling along a feeder lane to an ASL box that some cretin in the council failed to realise would be a death trap.

Possibly. But that doesn't make it anything but thoroughly stupid and suicidal to use it, does it?
