I never said anything about the military, I was talking about the public
service. The fact that the military doesn't exercise it's weight on that
is just silly A sign of where your tax money actually *does* get wasted.

Another related point: the military sure as hell does exercise such power
on larger contracts which may indeed be why they don't bother here. What's
the radio cost retail? $50-$100?

No, and that in short is the difference between the NTSB (which investigates
plane crashes and the occasional auto accident) and the DOT (which operates
NHTSA and a lot of other transportation organizations run by uneducated paper
pushers).

The push to replace engineers with uneducated paper pushers and with lawyers
at the US Patent office and the FCC has pretty much been complete, though.
There was a substantial amount of pressure applied in the eighties and
nineties to eliminate technical people in a number of agencies. It was combined
by rising salaries in the private sector too, for technical folks.

Civilian agencies are even worse. Part of the issue also is the fact that
the procurement people have no idea what they are buying (combined with the
fact that most of the salespeople have no idea what they are selling) and
don't really think about long term costs.

That's off by a figure of magnitude or two for typical field radio sets.
A great part of that cost is borne by the fact that they are small production
items and don't get the kind of economies of scale that consumer products
do. Hell, the battery pack for the cheapest handheld radio around, the
PRC-127, is more than $100. It doesn't come with schematics either.

Thirty years ago, everything came with full field and depot repair docs.
It's not like that any more.

Friday, March 5, 2010

(AP) -- Toyota has for years blocked access to data stored in devices
similar to airline "black boxes" that could explain crashes blamed on sudden
unintended acceleration, according to an Associated Press review of lawsuits
nationwide and interviews with auto crash experts.

The AP investigation found that Toyota has been inconsistent - and sometimes
even contradictory - in revealing exactly what the devices record and don't
record, including critical data about whether the brake or accelerator
pedals were depressed at the time of a crash.

By contrast, most other automakers routinely allow much more open access to
information from their event data recorders, commonly known as EDRs.

AP also found that Toyota:

- Has frequently refused to provide key information sought by crash victims
and survivors.

- Uses proprietary software in its EDRs. Until this week, there was only a
single laptop in the U.S. containing the software needed to read the data
following a crash.

- In some lawsuits, when pressed to provide recorder information Toyota
either settled or provided printouts with the key columns blank.

Toyota's "black box" information is emerging as a critical legal issue amid
the recall of 8 million vehicles by the world's largest automaker. The
National Highway Traffic Safety Administration said this week that 52 people
have died in crashes linked to accelerator problems, triggering an avalanche
of lawsuits.

When Toyota was asked by the AP to explain what exactly its recorders do
collect, a company statement said Thursday that the devices record data from
five seconds before until two seconds after an air bag is deployed in a
crash.

The statement said information is captured about vehicle speed, the
accelerator's angle, gear shift position, whether the seat belt was used and
the angle of the driver's seat.

There was no initial mention of brakes - a key point in the sudden
acceleration problem. When AP went back to Toyota to ask specifically about
brake information, Toyota responded that its EDRs do, in fact, record "data
on the brake's position and the antilock brake system."

But that does not square with information obtained by attorneys in a deadly
crash last year in Southlake, Texas, and in a 2004 accident in Indiana that
killed an elderly woman.

In the Texas crash, where four people died when their 2008 Avalon ripped
through a fence, hit a tree and flipped into an icy pond, an EDR readout
obtained by police listed as "off" any information on acceleration or
braking.

In the 2004 crash in Evansville, Ind., that killed 77-year-old Juanita
Grossman, attorneys for her family say a Toyota technician traveled from the
company's U.S. headquarters in Torrance, Calif., to examine her 2003 Camry.

Before she died, the 5-foot-2, 125-pound woman told relatives she was
practically standing with both feet on the brake pedal but could not stop
the car from slamming into a building. Records confirm that emergency
personnel found Grossman with both feet on the brake pedal.

A Toyota representative told the family's attorneys there was "no sensor
that would have preserved information regarding the accelerator and brake
positions at the time of impact," according to a summary of the case
provided by Safety Research & Strategies Inc., a Rehoboth, Mass.-based
company that does vehicle safety research for attorneys, engineers,
government and others.

One attorney in the Texas case contends in court documents that Toyota may
have deliberately stopped allowing its EDRs to collect critical information
so the Japanese automaker would not be forced to reveal it in court cases.

"This goes directly to defendants' notice of the problem and willingness to
cover up the problem," said E. Todd Tracy, who had been suing automakers for
20 years.

Randy Roberts, an attorney for the driver in that case, said he was
surprised at how little information the Avalon's EDR contained.

"When I found out the Toyota black box was so uninformative, I was shocked,"
Roberts said.

Toyota refused comment Thursday on Tracy's allegations because it is an
ongoing legal matter, but said the company does share EDR information with
government regulators.

"Because the EDR system is an experimental device and is neither intended,
nor reliable, for accident reconstruction, Toyota's policy is to download
data only at the direction of law enforcement, NHTSA or a court order," the
Toyota statement said.

Last week, Toyota acknowledged it has only a single laptop available in the
U.S. to download its data recorder information because it is still a
prototype, despite being in use since 2001 in Toyota vehicles. Three other
laptops capable of reading the devices were delivered this week to NHTSA for
training on their use, Toyota said, and 150 more will be brought to the U.S.
for commercial use by the end of April.

By contrast, acceptance and distribution of data recorder technology by
other automakers is commonplace.

General Motors, for example, has licensed the auto parts maker Bosch to
produce a device capable of downloading EDR data directly to a laptop
computer, either from the scene of an accident or later. The device is
available to law enforcement agencies or any other third party, spokesman
Alan Adler said.

Spokesmen from Ford and Chrysler said their recorder data is just as
accessible. "We put what you would call 'open systems' in our vehicles,
which are readable by law enforcement or anyone who has a need to read that
data," Chrysler spokesman Mike Palese said.

Nissan also makes its EDR data readily available to third parties using a
device called Consult, spokesman Colin Price said. The program allows access
to a host of vehicle data, from diagnosing the cause of a check-engine light
to downloading EDR data after a crash, he said.

However, Honda does not allow open access to its EDR data. Spokesman Ed
Miller said the data is only readable by Honda and is made available only by
court order.

In many cases, attorneys and crash experts say EDR data could help explain
what happened in the moments before a crash by detailing the positions of
the gas and brake pedals as well as the engine's RPM.

"Had Toyota gotten on the stick and made this stuff available early on, I
think they'd be in a better position than they are now," said W.R. "Rusty"
Haight, owner of a San Diego-based collision investigation company.

In congressional hearings on the recalls last week, U.S. Transportation
Secretary Ray LaHood said Toyota's EDR data cannot be read by a commercially
available tool used readily by other automakers. "Toyota has a proprietary
EDR, which is the system that only they can read," LaHood said.

The AP review of lawsuits around the country found many in which Toyota was
accused of refusing to reveal EDR and other data, and not just in sudden
acceleration cases.

In Kentucky, to cite one example, a recent lawsuit filed by Dari Martin over
a wreck involving a 2007 Prius sought information from Toyota to bolster his
claim that the car's seatbelt was defective. Toyota refused, contending
there was no reliable way to validate the EDR data and that an engineer
would have to travel from New Jersey or California at a cost of some $5,000
to retrieve it.

"There is simply no justifiable reason for Toyota not to disclose this
information," Martin's lawyers said in a court filing.

Lawsuits in California and Colorado have accused Toyota of systemically
withholding key documents and information in a wide variety of accident
cases, but no judge or jury has found against the car company on those
allegations.

Some crash experts say Toyota shouldn't bear too much criticism for failing
to capture large amounts or specific kinds of data, because EDR systems were
initially built for air bag deployment and not necessarily to reconstruct
wrecks. They also vary widely from vehicle model to model, said Haight, the
San Diego collision expert.

"That doesn't mean I'm hiding something or preventing you from getting
something," Haight said. "It simply means that, in the development of a car,
other considerations took priority - nothing more."
