Safe Airbags or No Airbags

The National Highway Traffic Safety Administration
( NHTSA) states that there has been a good return on
the enormous investment in Airbags; just
152 deaths for a statistical estimate of about 5000
lives saved. But the real number of airbag caused
deaths is greater. And this doesn't even
consider all the severe injuries caused by airbags
over the last 12 years.
The 152 deaths are only those airbag-caused deaths
that NHTSA =s
Special Crash Investigation (SCI) Division has
investigated and confirmed. In 1988, NHTSA decided
that their SCI
team would no longer investigate all
accidents where there were airbag-caused fatalities. There
were too many. Since the mission of the Special Crash
Investigation Unit was to help develop new, safer
airbag systems, they would only evaluate the
effectiveness of new airbag systems. From then
on, only the accidents that that
would help automotive engineers design safer airbags.
would be investigated.
This amounted to investigations of unusual accidents
and those where new airbag systems were in use. Since the objective of the SCI Unit is to help
investigate and develop improved airbags, this makes
sense. But it also means that ordinary airbag deaths have not been investigated, and only
those that are investigated are included in the
statistics.
The criteria NHTSA uses to decide on which
accidents to investigate has changed over the years. Since
December 1999, only accidents where the vehicles are
newer than the 1999 model year, and where advanced
airbag systems were in place were investigated.
Most
accidents chosen for investigation over the last few
years did not involve fatalities. By definition
all the Aordinary@
airbag caused deaths are ignored because they don=t
involve advanced airbag systems.
Government officials, and others in the auto
industry refer to the 152 confirmed airbag-caused
deaths as if they were the only fatalities. But
this is only a small portion of the real total; if all
the "ordinary" airbag-caused deaths were
counted- those that didn't involve the latest airbags
- how would this return on the airbag
investment look?
And what about injuries? Severe, disabling and
incapacitating airbag caused injuries are not even
tracked. The University of Louisville Hospital=s
Shock Trauma Unit sees about one severe, disabling
airbag caused injury per month (and about one regular,
non-disabling, injury per day). Since that hospital
serves about 450,000 people, and there is a total of
about 250 Million people in the USA , each year there
are about 556 severe, disabling injuries (not
including those outside the US). This means that a
better estimate is that there have actually been more than 5,600 serious, disabling injuries
caused by airbags over the last 12 years. And it=s
not just shorter women, children, those with medical
problems and the elderly, although these are the most
vulnerable groups.
For instance, Ed Platow, a six foot tall father of
two teenaged daughters living in New Jersey, was
driving in his neighborhood one day in the winter of
1996 in his Ford Crown Victoria. His car hit some
black ice and he slid toward the curb at about 25 Mph.
He remembers thinking that he may need to get his
wheels realigned just before the car hit the curb. But
the airbag broke his neck at the C4 level and today Ed
is a quadriplegic.
Sheree Bobrowski, a surgeon living in Riverdale,
NY, was in a very minor fender bender in 1992 but it
damaged her neck so badly that 5 vertebrae had to be
surgically removed. Today she can =t
work at all and will have to wear a neck brace and use
crutches for the rest of her life. Worse, she is in
constant pain. There were no other injuries in the
accident and if she had not had an airbag, she would
have walked away.
The irony is that neither Sheree nor Ed count
statistically. NHTSA does not track injuries and the
information is not even discussed.
NHTSA estimates on a purely statistical basis that
5,000 lives have been saved by airbags. Add the 5,600 plus
disabling injuries to the uncounted "ordinary"
airbag-caused deaths, plus the 152
investigated deaths, and the trade-off seems far less
attractive.
Important research by leading emergency medicine
physicians like Dr Wm. Smock, of the University of
Louisville, shows that everyone is in danger of
severe injury; not just those who fall into NHTSA =s
specially endangered categories. The airbag cover
blows off at around 200 mph.
Dr Smock compares the
impact of this detonating airbag cover, which also
doubles as the horn cover on most cars, to driving
along at 200 mph with your arm out the window.
Suddenly your arm hits a metal sign covered in
plastic. The force is enormous; about six times
greater than the human body can stand. Dr
Smock=s
research
documents several example cases in which fingers were
amputated, arms crushed (i.e. more than 30 fractures
in the arms) from having hands or arms near the airbag
cover. If your arm, hand or face is in front of
the cover when the airbag detonates, the injuries can
be disabling, if not fatal.
And the problem is made
worse because we all learned to drive with certain
habits. For instance, keeping your hands near the top
of the wheel, blowing the horn just before impact, or
crossing one arm over the steering wheel cover when
turning are all methods we learned many years ago. But
they all can lead to severe injuries when airbags are
involved.
NHTSA has always claimed, on one hand that airbags
are Asafe@,
but also is giving auto manufacturers until 2012 to
manufacture a vehicle with a Asafe@
airbag (extended from the 2006 original deadline
because no manufacturer is close yet).
But nobody knows what a Asafe@
airbag will be. Will it keep the bag from going off if
a child is in the front passenger seat? What if the
driver or passenger is out of position when the impact
occurs? These are issues now being pondered by
automobile engineers.
Meanwhile, each year new experimental airbag systems
are
being produced. Mercedes has child=s
car seat that turns off the airbag on the passenger
side but also turns the bag back on if the
passenger weighs more than 70 pounds. In late 2000, Cadillac
introduced an airbag system with 38 separate
sensors that tries to determine who is in the passenger seat so
that the bag=s
force can be adjusted to account for children. And the
other car makers are working on their own versions
too. The only thing the new systems all seem to have
in common is that they are complex, electro-mechanical
systems. And in the real world these complex new
systems require a lot of real world testing before
they can be considered dependable. Remember, they need
to deploy in an accident in less than 50 thousandths
of a second,
even if the accident happens 20 years after the car is
made.
All this may lead to another foreseeable disaster.
The new regulations will no longer allow airbag on off
switches in cars after 2012, under the assumption that
the systems will be infallibly safe by then. Never
mind that there have been
more than 4 million cars recalled for airbag related
problems since 1996. And compared to the new
airbag systems, the recalled cars had very simple and
straightforward airbag systems. Until now, almost all
airbag systems have used momentum-actuated crash
sensors located in the front of the car to signal a
detonation impulse. How likely is it that the new,
highly complex, electro- mechanical systems with
multiple sensors will be infallible in real life
applications after 2002? Ask any engineer with real
world experience.
How did we get into this mess? Congress mandated
airbags with erroneous information provided by people
like Ralph Nader and Joan Claybrook, then
Administrator of NHTSA. An article written by the
Competitive Enterprise Institute recently showed a
photo of Ralph
Nader demonstrating for Congress how airbags would
allow children to ride in the front seats without
seatbelts. Despite reservations by automotive
engineers and and auto industry leaders like Lee
Iacocca, they passed a law to require airbags before
they had been properly tested. Part of the new
requirements for advanced airbags (also called
"safe airbags") being considered by NHTSA today require
testing with a whole family of crash dummies and crash
dummies with out of position occupants. Until now,
only one size of crash dummy has been used.
The real solution is that airbags should not be
required until they are designed, developed, tested
and proven safe under real world conditions. Until
then Congress should repeal the airbag requirement and
allow anyone to have an airbag on/off switch installed
who wants one. Tax Credits or some similar mechanism
should be in place to help pay for the switch.
This proposal makes sense if we have to have
airbags at all. But if airbags were optional
and manufacturers had to worry about defending them in
court today, it=s
unlikely that they would be offered even as an option.
The liability of installing a "safety
device" that severely endangers most of the
population would be too great for any manufacturer. But because Congress
requires them in all passenger cars, trucks and vans
today, the manufacturers are protected by the mandate
unless the air bags do not work as designed.
Today there are
more than 130 million vehicles on the road with
airbags. Leave the situation as it is, and
everyone driving in front of an airbag or sitting in
the passenger seat is in danger. Everyone should be
able to protect themselves and their families from
these government- mandated menaces.
Yes, this could be expensive. But the lives saved;
the people who will not be disabled and live as
quadriplegics or in perpetual pain will be worth
it.
