Is it time to start calling out bad cyclists?

Mr Johnson insisted that he would work to improve the capital for cyclists. “There is much, much more we can do to make London one of the great cycle cities of the world,” Mr Johnson said. “Believe me, I have that commitment.”
He said that the two goals of speeding the flow of traffic and keeping cyclists safe were not incompatible. The Mayor was criticised for claiming that 62 per cent of people killed or seriously injured while riding a bicycle were breaking the rules of the road when they were knocked off their bikes.

I'd like to see the source of that 62% figure.
