<sigh> Why is this hard to understand?
It's not _necessary_ to have a statistician standing at every accident
site. That's not how this stuff works. If helmets prevent as many
injuries as claimed, then the tremendous surge in helmet use in the past
15 years should have caused a big drop in head injuries per cyclist.
But it hasn't! If anything, more data shows a _rise_ in head injuries
per cyclist. (See
http://www.cyclehelmets.org/1028.html)
Some people have claimed that helmets are wonderfully protective, but
that - through amazing coincidence - cycling has gotten much more
dangerous in exact proportion to the helmets' use and protection. It's
a strange argument - sort of like this:
"My rabbit's foot is perfect protection against elephant attacks. Yeah,
I know there weren't any elephant attacks before I got my rabbit's foot,
but there _would_ have been if I didn't have it!"
But even that "reasoning" is belied by studies examining head injury
rates when helmets are forced on people all at once. In some places,
helmet use suddenly tripled (to as much as 90%) because of helmet laws.
One classic paper examined cyclists' head injury hospitalizations
while that sudden increase happened (just before a MHL), and found no
detectable improvement at all. ("Trends in Cycle Injury in New Zealand
under Voluntary Helmet Use", Scuffham, P. et. al., Accident Analysis &
Prevention, vol 29 no 1)

I understand that getting injured as you did must be psychologically, as
well as physically, traumatic. It's not uncommon for people who survive
an airplane crash to never fly again - despite the airlines' tremendous
safety record. It's not uncommon for people to develop unrealistic
fears of everything from dogs to spiders to canoes, based on one bad
experience.
But I'll take the real-world data over your single experience, thanks.
That data indicates I would have to cycle for thousands of years to get
up to a 50% chance of dying on the bike, even if I can keep doing
thousands of miles every year. My risk per year is literally negigible.
More to the point, my risk is not affected by the presence or absence
of a helmet.
And if I do pay attention to individual experiences, I prefer my own.
I've been riding seriously as an adult for over 30 years now, and as a
kid for, oh, at least 15 years before that. I've never had an injury
worse than a childhood scraped knee. And like almost all the world's
cyclists, I probably never will.
And let me ask you something. If you knew you were
> going to get hit, would you rather be wearing a helmet or not?
Did you mean while walking, where the risk of fatal head injury per hour
is about twice that of cycling? Or did you mean while riding in a car,
where the risk is almost exactly the same?
Or did you mean we should wear a helmet _only_ while cycling? If so...
why only then??
