It should be a matter of individual choice, not compulsion.
Weird... I don't agree at all.
When I was a teenager, I didn't want to wear one because it was un-cool.
Now I wouldn't dream of not wearing one. Surely it's the minimum safety
precaution to take whether effective or not.
That makes no sense - why do something that isn't effective?
Quoted message said:I also remember a doctor friend of mine saying his colleagues referred to us
cyclists as 'organ donors' or some such...
Being a doctor doesn't make someone an expert on something outside their
field of expertise. Would you trust a doctor who said "this bridge is
safe" when a structural engineer had told you it was about to collapse?
Quoted message said:Erm... I think it should be compulsory for all, and not just as the article
calls for, under 14 year olds.
Cycle helmets make cycling more dangerous. This may seem the opposite
of what you'd expect, but it's true and borne out by proper scientific
research.
1. Wearing a helmet makes a cyclist appear "more protected" to car
drivers. This causes some car drivers to take fewer precautions around
helmeted cyclists than non-helmeted ones. This is called "risk
compensation".
2. Wearing a helmet increases what's called the "rotational diameter" of
your head. This increases the chance of neck-twisting of the kind that
can cause paralysis or even death in the event of falling / being
knocked off the bike and sliding along the road. This works the same
way as having a larger steering wheel makes a car without power steering
easier to drive, because it takes less force to turn the wheel.
3. As you commented, helmets put people off cycling. This leads to
fewer cyclists on the road, which means motorists become less familiar
with encountering cyclists and hence more likely to make mistakes and
mis-judge speeds, overtaking, etc.
4. Other countries have introduced laws forcing cyclists to wear
helmets. In every case, the result of this has been both a decrease in
cycling in general, and an *increase* in the number of cyclists killed
or seriously injured on the roads in those countries.
It's common for medical people like paramedics, who know a lot about
medicine but rather less about materials engineering, to assume that a
broken helmet has "saved" the wearer from a head injury. This seems
obvious, "common sense" says that the force which broke the helmet has
been absorbed and thus not affected the rider's head. In fact this
isn't the case. Cycle helmets are made of a kind of polystyrene. This
is designed to absorb energy by bending - as soon as it breaks, all the
energy is delivered un-hindered to the head under the helmet. So a
broken helmet after a crash has done nothing at all to protect its
wearer.
Looking at the bigger picture, one of the major causes of premature
death is obesity and its side-effects. Encouraging people to cycle
instead of driving on local trips is a very effective way to encourage
more exercise and less obesity. That we all need to take more exercise
and use our cars less is something the vast majority of people agree on,
including the Government and the British Medical Association. Compulsory
helmet laws are bad for cycling and thus bad for the nation's health in
general. We don't need laws, we need more cyclists.
Lastly, look at countries like Holland, where thousands of people use
bikes as their normal every-day transport round town. They don't have
helmet laws and most of them don't wear helmets - indeed they cycle the
same way they drive, in their ordinary everyday clothes. These
countries have the lowest rates of cyclist injury in the world.
Helmets are bad for cycling. By all means wear one if you want to, but
please don't try and force them on the rest of us. They do *not* help
cyclist safety. Don't just take my word for it, see

information on the subject.
