Those of you who like statistics might like to glance at this nicely presented survey of cycling near misses in London.
It turns out, that it would be, on average, 400 years before a regular UK commuting cyclist would experience death or a serious injury. In contrast, s/he is likely to experience a ‘very scary’ incident once every week (this is London!) So they surveyed near misses to get more data, like they do for flight safety analyses.
The same lady has done some interesting work on how to influence cycling policy see the video on her website here.
