Ah. Don't have time to read EVERY reference sadly.
That seems not inconsistent with common sense. However it still does not prove. let alone imply, a causal connection.
It could be that it coincided with an unusually hot summer, and a world cup victory, with more drink pedestrians and cyclists staggering around (than usual).
I always like the old question 'how can the incidence of drawn test matches affect the size of tree ring growth' It turns out they are both likely due to unusually wet summers.
An interesting statistic, that sadly,proves nothing. What, for example, is the standard deviation on pedestrian and cyclist death in the years prior to and subsequent of this survey?
If anything, it might show that motorists who feel secure (i.e. by adhering slavishly to speed limits) are more likley to mow down pedestrians.
There. I can spin it as well as any BBC reporter or government communications officer.
I DID NOT HAVE SEX WITH THAT DOSSIER!!!
