I don't know of _anyone_ who would forbid or outlaw helmet wearing.
But I've met many people who approve of laws requiring helmets. And
we know that those people have passed mandatory helmet laws in many
jurisdictions.

Yet every time this subject comes up, you argue as strongly as you can
_against_ those who most oppose MHLs. You have _never_ "given grief"
to anyone speaking in favor of helmets in any way.

Let's see: In the US, there are only about 750 fatalities from
bicycling in a year - a figure roughly equal to the deaths from poison
gases. But there are hundreds of thousands of fatalities each year
from heart disease; from stroke; from lung disease.

Major causes of medical expenses in this country are lack of exercise
and obesity.

About 40,000 motorists die each year, most from head injuries. Tens
of thousands of people are killed due to falls while just walking
around their own homes.

So quit hiding your private information! We demand to know your age,
your weight, your percent body fat, your diet in detail for the past
six months (including whether you eat meat), the amount of alcohol you
consume, and how much time you spend in contact with cigarette smoke.
We want to know how many hours you drive in a year, and how many hours
you swim. We want to know whether you live in a place that has those
ridiculously hazardous things called "stairs," and whether you wear a
helmet when walking down them. We want to know what caused the death
of each of your relatives. We want to know whether you ever play
basketball (the number one recreational reason for visiting an ER).

And before you decide to do something really risky - like ride a
motorcycle, or go up in a light plane - we want you to clear it with
all of us here. Get our permission first, dammit!

Because all those things are probably worse than bicycling. And it
makes sense to try to protect the group from excessive levies. Right?

You're confusing _your_ imagination of risk with the actual level of
risk.

That is, because you can imagine cyclists running into posts, and you
remember a bit of physics, you think you've got a good assessment of
the relative risk.

But your estimate doesn't match reality. Look at the comparisons
between cyclists and pedestrians in the tables at
http://www.ctcyorkshirehumber.org.uk/campaigns/velo.htm

Cycling really does seem to be safer than walking, at least near
traffic. That's largely because bicyclists are vehicles, and they
generally flow along with the traffic, following the same rules.
Those rules are well-designed to minimize conflicts. Pedestrians
operate by different rules, traveling along different paths that
intersect motor vehicle paths at odd moments. It's a more chaotic
situation.

Bicycling is NOT very dangerous. It does us no good to pretend it is.

Interesting. Earlier, you said scientific arguments and presentation
of facts won't work regarding mandatory helmet laws. Why? Because
they are a political issue.

Now you're saying if more than one person is involved, _everything_ is
a political issue.

It follows that you believe science and data have no value, except
perhaps to hermits living alone on mountain tops! That's one of the
most anti-intellectual points of view I've ever heard.

How do you make your personal decisions? By examining the entrails of
sacrificed animals?

This is true. Also, what many AHZ's apparently don't understand
(actually they do understand it but they pretend not to) is that a 30
mph collision does not usually result in a 30 mph head impact. By the
time the cyclist's head impacts something, the rate of impact is greatly
reduced by decelleration (sliding against the road, etc.).

Which is part of why bicycling mishaps rarely result in more than minor
injuries foam hat worn or not.

LOL! So you start sliding before you hit the road, do you?

Here's an extract from the Transport Research Laboratory's report
PPR213:

"in both low speed linear impacts and the most severe oblique cases,
linear and rotational accelerations may increase to levels
corresponding to injury severities as high as AIS 2 or 3, at which a
marginal increase (up to 1 AIS interval) in injury outcome may be
expected for a helmeted head. The true response of the bare human
head to oblique, glancing blows is not known and these observations
could not be concluded with certainty, but may be indicative of
possible trends. A greater understanding is therefore needed to
allow an accurate assessment of injury tolerance in oblique impacts.
Linear impact performance, head inertia and helmet fit were
identified as important contributory factors to the level of induced
rotational motion and injury potential. The design of helmets to
include a broad range of sizes was also concluded to be detrimental
to helmet safety, in terms of both reduced linear and rotational
impact performance. The introduction into EN1078 of an oblique
impact test could ensure that helmets do not provide an excessive
risk of rotational head injury."

Redux: cycle crashes are complex, helmet tests are overly
simplistic, helmets might make the worst kind of injuries worse.

All of which may contribute to explaining why large-scale increases
in helmet wearing have *never* produced a measurable change in head
injury rates in *any* real cyclist population. Obviously it's not
as simple as you make out.

For life insurance, all of this is considered. Obesity, cholesterol,
dangerous activities, etc. With employer provided health insurance I
guess they could base the employee contribution based on this, but I
don't know of any employer that does that.

I know that in some states that have lifted the motorcycle helmet law,
they require proof of health insurance.

The number of bicycle accidents where a helmet would make a significant
difference is so small that it makes no sense to classify bicycling as
an activity that has an impact on insurance rates.

just pass a law allowing insurance companies an exemption that people who
fail to take reasonable precautions(seatbelt or helmet for cycles) cannot
make a claim against their insurance.Then they can make their choice as
they see fit,and live by the consequences of their choice.

Of course,by law,hosptal emergency rooms STILL have to treat them,and that
cost just gets added to everyone's medical expenses.
(like all the illegal aliens who use emergency rooms as their primary care
provider)

So I'd guess there must be a commensurate number of
serious injuries. Let's define 'serious' for the moment
as "expensive". How many? 3X? 4X? That would be 3000
serious injuries. How serious? Let's guess $10,000
average seriousness. That's $30M a year. But the vast
majority of cyclists must have insurance. So the levy
on the public might be somewhere in the range of 3 to 6
M$ a year. Each person's share of that is about 1 or 2
cents per year. I'd not call that a heavy levy. I'd
say, if we can decide that bike helmets really help,
then I personally would wear one - usually, but I'd
hate to get a ticket if I skipped the helmet one day
to ride 6 blocks over to my friend's. I think maybe
this mandatory helmet law isn't all that good an idea.

So let's have a universal no smoking law. It costs me
400 to 800 dollars a year in defraying medical expenses
for smokers.

Chewing is exercise!

It may eventually be possible to get robots to drive the
vehicles. I don't think that area's getting enough focus.
The technical problem itself is almost trivial, it's the
social acceptance, funding, legals, etc. People want the
robot to drive them from A to B while they sleep, but it
would be a tremendous advance if we could just tell the
computer to drive along this road here and don't hit
anything. Tell it turn here, park there.

That's easy. Zero. I'm a Mormon.

Well, about six minutes a year. If I have to go into

for most of us, you might be able to guess this answer.

I used to swim a lot, like an hour a day. But I was

getting one of those job things so I can buy my own pool.

I am not sure that "decreases gradually" is totally correct. Mills
{1} in his study of bicycle helmets says "A good helmet should protect
the wearer for impacts up to 15 mph into a rigid flat surface." and
"Once the foam is more than 90 percent compressed it bottoms out and
the force on the head rises rapidly."

It looks to me like there the shock protection works to a point and
then catastrophically fails. I don't remember if Mills gives a point
when the helmet foam is expected to compact to 90%

So of course why wear one at all! People who argue that would also tell
cops not to bother with bullet-proof vests because A) they won't stop AK47s
and B) they won't prevent fatal head shots.

For some values of reasonable. According to the largest ever study,
encompassing over a million bike accidents, wearing a helmet is
associated with a small but significant increase in risk of death
and a small but statistically insignificant increase in risk of
injury.

Yes, I did type that correctly, it is *increase* not decrease. So
arguably insurance companies should be telling people not to wear
them.

Actually, of course, it's nothing like that simple. Which is
probably why the insurers of large cycling bodies like CTC and LAB
do not make any stipulation in regard to helmets on their group
rides.

There are more bicycles in the world than cars and they are being

Then eventually you WILL have helmets. Nanny wouldn't have it any other
way. And mandatory sun glasses and sun screen on days when the sun
shines. And classes on the save use of a bicycle. And a Licence to buy
one. And insurance. And road tax. And ...
