The point I made about lights and hi-viz (and I did mean hi-viz with reflectives) was simply to illustrate the point that some protective measures are so obviously useful that waiting for someone to produce evidence is a waste of time. And as someone who cycles and drives in a rural I think cycling at night without good lights and some reflective / hi-viz clothing shows a lack of what my mother used to call "common sense". When I am driving I frequently remark to my (bored) passenger just how visible a distant cyclist is because of what they are wearing. This thread is about helmets, so please don't spend too long on this example.
I'm sorry, but I must reiterate that there is no such thing as a 'no brainer'.
What if there was evidence that wearing a helmet put an individual at slightly greater risk by wearing a helmet? Would you still wear a helmet?
Or, for that matter hi-viz? Would you say it was common sense, then?
This thread may be about helmets, but IMO, it is relevant to discuss other 'safety' equipment for cyclists because many people use the same 'common sense' argument about helmets and conspicuity garments. And furthermore pressure to use these items is often used as an excuse not to do anything else.
This study shows a non-significant increased risk associated with the wearing of conspicuity aids http://eprints.nottingham.ac.uk/12855/
At any rate, it does not produce the improvement in crash rates that would be expected of something that is just 'common sense'.
This study shows some mixed results http://www.sciencedirect.com/science/ar ... 7513005113
During dark conditions, crude estimates indicated that reflective clothing or other items, red/orange/yellow front upper body clothing .... were estimated to increase the odds of a [motor vehicle (MV)] collision.
One or more visibility aids reduced the odds of a bicyclist MV collision resulting in hospitalization.
Very often, the reaction to increased attention on cyclists safety is to increase the the pressure for the use of personal safety equipment. To simply accept them without evidence is problematic, and IMO, just encourages people to carry on with the biggest red herrings in road safety.
