You'd think so, wouldn't you? Unfortunately, the evidence (which
admittedly is complex and hard to interpret) doesn't seem to show this.
Cyclists who wear helmets are very slightly /more/ (not /less/) likely
to be killed or seriously injured, world wide. It's much, much safer to
ride a bike in Holland, for example, where very few cyclists wear
helmets, than in the US where many more cyclists do. Of course this is
not cause and effect - probably just the opposite.
But because of the way impacts and injuries scale, the protection offered
by a helmet at normal road speeds is very, very small indeed. Many of us
who have studied the evidence still wear helmets when riding off road.
Some of us still wear helmets when riding on road. But in reality they
will save you from nothing more than minor cuts and bruises.
The antipathy, though, is not to helmets as such - it's to people who
have exaggerated belief in their utility. If you put your computer in a
box, surrounded it with 1.5cm of polystyrene foam, and put it out in the
middle of the road for a car to hit at 30mph, would you expect it to
work afterwards?
