Anyone know the equivalent number for car drivers/passengers?
Have a search for something that User1314 posted in the Campaigning forum. Off the top of my head, the figures for deaths for cyclists, pedestrians and drivers/passengers are very similar indeed per hour, and pretty similar per kilometre. Cycling is far more likely to result in a trip to hospital than other modes of transport, but most of those of trips to hospital result in nothing more than a quick burst of treatment - certainly nothing life-changing. And there are Dutch stats (I think I saw them courtesy of Pedrosanchezo's witterings in the helmet forum) which say that 4 out of 5 cycling incidents resulting in a hospital trip involved no other road user.
In the context of 2,000,000 regular cyclists and increasing, 120 deaths is a tiny risk. The roads certainly could be safer (and are getting safer), and there are elementary precautions such as not going inside lorries that individuals can take. But in the grand scheme of things cycling is incredibly safe.
