Brian,

It is 4 out of 38 deaths that were contact from behind, not 4%. But there were 11 sideswipes. Serge would argue that the cahnce of sideswipe is increased by bike lanes. I wonder and thnik it may be more on a cse by case basis. When a bike lane is wide enough it should also prevent side swipes. But many bike lanes are far from wide enough.

It is clear that this was a report done by the coroner well after the fact (the report has some comments on what information should be gathered in the future). Many of the numbers have limited worth, like number of incidents by age. If the numbers riding by age are unknown then it hardly gives an indication of what ages might be more at risk.

There is even one 'conclusion' that seems to be very misleading. The report says the frequency of incidents is highest during the rush hours. The problem is frequency is a slippery term. Is it per hour or per 1000 riders. In this the numbers are striking for daylight vrs. 'dark' hours. 8 out of 38 were during non-daylight hours. I think that shows a very much higher rate per cyclist for after dark.

Oh and 55% of the deaths were from head injuries, yet only 3 cyclists had helmets (That does not mean 35 were without, for some it was not indicated on the reports).
