Boris bikes and cycle superhighways - your views needed

So have there been any serious accidents or fatalities yet on/with a Boris Bike? If not that in itself is big news. I have seen quite a few wobbly riders over the last few weeks, perhaps the general public are good on bikes, or drivers are been forced to be more aware of cyclists. What are your thoughts?

There is evidence to show that the more people there are cycling in a city the safer it gets. Therefore hire bikes will lead to a reduction in accidents and, one would imagine, if accidents do happen they will happen to the inexperienced sorts on the hire bikes and therefore make life safer still for me. Sounds good.
