As has already been said, either you obviously haven't bothered to read anything on
the site or you aren't actually interested in informed debate of the subject, just spin...
Your user name does rather imply that you just interested in spin.
OT but Spin has more than one connotation and at least one more relevant to cycling than the relative recent appropriation of the word to mean Political Dishonesty. just a thought before you hang your argument on someones choice of anonymous username.
Right now I shouldn't be in bed, but should be on my roof looking for the small leak dripping into my loft. Ironic eh?
Anyway onto topic.
Older helmets tend to offer more protection because they were bigger, thicker and had less vents than the microlight 20+ hole modern things- hence more structure around your head to absorb an impact with.
Also all the studies for and against won't make a scrap of difference to the majority of people, who will use other purely subjective assessments relevant to themselves.
I got one initially as I thought it was the right thing to do and wore it if I remembered to pick it up in the morning, until I went over a car and landed pretty much top of my head first on the road. When the medics took my helmet off it was in several pieces under the plastic shell. Several medically qualified people that looked at me in hospital told me it was the difference between a fractured skull with brain injury or just a big concussion.
therefore I wear a helmet all the time now. Other people haven't had the same accident or don't want to have helmet hair or are happily convinced by the helmets are no use argument, good luck to them, they do their thing, I'll do mine.
We might as well be arguing about our favourite colour or which shape pasta cooks best.
