I'm not sure about the specific thrust of your question--standard comments would include not to read too much into one year's stats--you need several years to really understand trends--, that as far as we know cycling is still increasing at a faster rate than crashes, that the crash rate in London, while too high, is still pretty low. That said, there has been very little progress for the better on the street network at large and quite a lot of regression (nonsense like 'smoothing the traffic flow'). There's still a huge amount of work to do to change the stone-age thinking that prevails in certain quarters, so no reason for complacency.
