Your talk about 40 km/hr crashes reminds me of what happened to the teenage son of a friend. He
was wearing a helmet and was hit by a car at about 40 km/hr. He was carted off to hospital and
died of head injury a few hours later. Of course, speed isn't the only factor here - cars
travelling at 40 km/hr have a fair bit more momentum than a cyclist at the same speed. As this
tragedy shows only too well helmets can't prevent death from head injury in cases like this.

These empirical results have convinced you that, for your type
of cycling - racing and and spanking along at 40 km/hr, you'd be
better off wearing a helmet. I couldn't agree more! You are far
and away the best person to make that decision. You know how and
where you ride and have direct experience of the risks you face.
That doesn't mean stats, which essentially represent the 'average' cyclist have no meaning. You
have chosen how you ride, and understand how this affects your risk of head injury.
However, studies show that 'average' adult cyclists riding for transport are most likely to suffer
a head injury, especially a serious head injury, if they are hit by a motor vehicle. Most of us
don't ride into cars. For responsible adult cyclists riding in traffic, it's usually the motorist
who is at fault.
So the average responsible cyclist riding in traffic has little or no choice about the risk of
head injury. Data from Victoria shows that the increased helmet wearing because of the law had no
effect on this type of head injury - if anything the risk was actually higher after the law. At
the time, it was postulated that motorists became less aware of cyclists because fewer people
cycled, so perhaps they started to brake a fraction of a second later, and so were more likely to
hit the cyclist, or hit at a slighly higher speed.
One researcher in the US has now assembled 9 different datasets to confirm this theory. That
paper, called 'Safety in numbers: More walkers and bicyclists, safer walking and bicycling' will
soon be published in an international safety journal.
That research explains the stats on head injury rates per cyclist, which actually increased with
the helmet laws in Australia. Most serious head injuries to cyclists riding for transport happen
because of collisions with motor vehicles and so, if the risk of being hit by a motor vehicle
increases, so will the risk of serious head injury per cyclist, despite increased helmet wearing
because of the law.
Few people would argue with RMan about his decision to wear a helmet, based on his own personal
experience. He's the best person to judge. But the same applies to other cyclists, who have
different experiences and also different risks. They, too, are the best people to judge.
What we should all do, is argue we should be allowed to make this choice, because taking away the
right to choose discourages cycling, and that (as this soon to be published research shows only
too clearly) increases the risk for everyone who cycles on the roads.
