Silas Denyer opined the following... 3. Approximately 1% of all pedestrian deaths are caused by bicycles 4. Approximately 1% of all pedestrian detahs are caused by cars running red lights I know that you have admitted that your analysis is flawed, that the data is inaccurate etc. but you still seem to expect people to accept it as a way of forwarding your argument. Actually I admitted that the data from which I extrapolated was flawed. The figures in 3. and 4. are absolutes, not extrapolations. I have not seen any cogent argument that any of the following figures are inaccurate: a) the total number of pedestrians killed by vehicles of all kinds b) the total number of pedestrians killed by bicycles c) the total number of pedestrians killed by cars crossing lights at red These data are sound. Given that you're not comparing like-with-like at all above (What percentage of pedestrian deaths were caused by bicycles running red lights?) what hope do you have of convincing anyone that the policy of penalising drivers for running reds, but not cyclists, is wrong? In fact what I have been arguing for is the policing of cyclists. Cycles running red lights unpenalised are a manifestation of a failure to police. The stats do _not_ show that you as a pedestrian are as likely to be killed by a bike as by a car. They do _not_ show that you are likely to be killed by a bike running a red. They do show that as a threat to your life as a pedestrian, your biggest concern should be a car. Do I then find it surprising that the police concentrate on cars? Not really. They do, however, show that you are as likely to be killed by any particular bike as by any particular car running a red light, which is still statistically significant! If I said that eating crayfish was as likely to kill you as a car running a red light, the public would see that as a significant risk (rightly or wrongly). The fact that the killer crayfish wasn't running a red light at the time would be irrelevant, as the point about the relative scale of the risks would still have been made. Silas |
