What to Fear
Nice rundown of the statistics.
The single greatest killer of Americans is the so-called “lifestyle disease.” Somewhere between half a million and a million of us get a short ride in a long hearse every year because of smoking, lousy diets, parking our bodies in front of the TV instead of operating them, and downing yet another six pack and / or tequila popper.
According to the US Department of Health and Human Services, between 310,000 and 580,000 of us will commit suicide by cigarette this year. Another 260,000 to 470,000 will go in the ground due to poor diet and sedentary lifestyle. And some 85,000 of us will drink to our own departure.
After the person in the mirror, the next most dangerous individual we’re ever likely to encounter is one in a white coat. Something like 200,000 of us will experience “cessation of life” due to medical errors—botched procedures, mis-prescribed drugs and “nosocomial infections.” (The really nasty ones you get from treatment in a hospital or healthcare service unit.)
The next most dangerous encounter the average American is likely to have is with a co-worker with an infection. Or a doorknob, stair railing or restaurant utensil touched by someone with the crud. “Microbial Agents” (read bugs like flu and pneumonia) will send 75,000 of us to meet the Reaper this year.
If we live through those social encounters, the next greatest danger is “Toxic Agents”—asbestos in our ceiling, lead in our pipes, the stuff we spray on our lawns or pour down our clogged drains. Annual body count from these handy consumer products is around 55,000.
After that, the most dangerous person in our lives is the one behind the wheel. About 42,000 of us will cash our chips in our rides this year. More than half will do so because we didn’t wear a seat belt. (Lest it wrinkle our suit.)
Some 31,000 of us will commit suicide by intention this year. (As opposed to not fastening our seat belts or smoking, by which we didn’t really mean to kill ourselves.)
About 30,000 of us will die due to our sexual behaviors, through which we’ll contract AIDS or Hepatitis C. Another 20,000 of us will pop off due to illicit drug use.
The next scariest person in our lives is someone we know who’s having a really bad day. Over 16,000 Americans will be murdered this year, most often by a relative or friend.
Leaving Infants in the Car
It happens; sometimes they die.
“Death by hyperthermia” is the official designation. When it happens to young children, the facts are often the same: An otherwise loving and attentive parent one day gets busy, or distracted, or upset, or confused by a change in his or her daily routine, and just… forgets a child is in the car. It happens that way somewhere in the United States 15 to 25 times a year, parceled out through the spring, summer and early fall.
It’s a fascinating piece of reporting, with some interesting security aspects. We protect against a common risk, and increase the chances of a rare risk:
Two decades ago, this was relatively rare. But in the early 1990s, car-safety experts declared that passenger-side front airbags could kill children, and they recommended that child seats be moved to the back of the car; then, for even more safety for the very young, that the baby seats be pivoted to face the rear.
There is a theory of why we forget something so important: dropping off the baby is routine:
The human brain, he says, is a magnificent but jury-rigged device in which newer and more sophisticated structures sit atop a junk heap of prototype brains still used by lower species. At the top of the device are the smartest and most nimble parts: the prefrontal cortex, which thinks and analyzes, and the hippocampus, which makes and holds on to our immediate memories. At the bottom is the basal ganglia, nearly identical to the brains of lizards, controlling voluntary but barely conscious actions.
Diamond says that in situations involving familiar, routine motor skills, the human animal presses the basal ganglia into service as a sort of auxiliary autopilot. When our prefrontal cortex and hippocampus are planning our day on the way to work, the ignorant but efficient basal ganglia is operating the car; that’s why you’ll sometimes find yourself having driven from point A to point B without a clear recollection of the route you took, the turns you made or the scenery you saw.
There are technical solutions:
In 2000, Chris Edwards, Terry Mack and Edward Modlin began to work on just such a product after one of their colleagues, Kevin Shelton, accidentally left his 9-month-old son to die in the parking lot of NASA Langley Research Center in Hampton, Va. The inventors patented a device with weight sensors and a keychain alarm. Based on aerospace technology, it was easy to use; it was relatively cheap, and it worked.
Janette Fennell had high hopes for this product: The dramatic narrative behind it, she felt, and the fact that it came from NASA, created a likelihood of widespread publicity and public acceptance.
That was five years ago. The device still isn’t on the shelves. The inventors could not find a commercial partner willing to manufacture it. One big problem was liability. If you made it, you could face enormous lawsuits if it malfunctioned and a child died. But another big problem was psychological: Marketing studies suggested it wouldn’t sell well.
The problem is this simple: People think this could never happen to them.
There’s talk of making this a mandatory safety feature, but nothing about the cost per lives saved. (In general, a regulatory goal is between $1 million and $10 million per life saved.)
And there’s the question of whether someone who accidentally leaves a baby in the car, resulting in the baby’s death, should be prosecuted as a criminal.

Friday Squid Blogging: Safe Quick Undercarriage Immobilization Device (SQUID)
New security device:
But what if an officer could lay down a road trap in seconds, then activate it from a nearby hiding place? What if—like sea monsters of ancient lore—the trap could reach up from below to ensnare anything from a MINI Cooper to a Ford Expedition? What if this trap were as small as a spare tire, as light as a tire jack, and cost under a grand?
Thanks to imaginative design and engineering funded by the Small Business Innovation Research (SBIR) Office of the U.S. Department of Homeland Security’s Science and Technology Directorate (S&T), such a trap may be stopping brigands by 2010. It’s called the Safe Quick Undercarriage Immobilization Device, or SQUID. When closed, the current prototype resembles a cheese wheel full of holes. When open (deployed), it becomes a mass of tentacles entangling the axles. By stopping the axles instead of the wheels, SQUID may change how fleeing drivers are, quite literally, caught.
Of course, there’s a lot separating a cool idea from reality. But it is a cool idea.

Red Light Cameras Don't Work
Interesting: the solution to one problem causes another.
“The rigorous studies clearly show red-light cameras don’t work,” said lead author Barbara Langland-Orban, professor and chair of health policy and management at the USF College of Public Health. “Instead, they increase crashes and injuries as drivers attempt to abruptly stop at camera intersections.”
Comprehensive studies from North Carolina, Virginia, and Ontario have all reported cameras are associated with increases in crashes. The study by the Virginia Transportation Research Council also found that cameras were linked to increased crash costs. The only studies that conclude cameras reduced crashes or injuries contained “major research design flaws,” such as incomplete data or inadequate analyses, and were always conducted by researchers with links to the Insurance Institute for Highway Safety. The IIHS, funded by automobile insurance companies, is the leading advocate for red-light cameras since insurance companies can profit from red-light cameras by way of higher premiums due to increased crashes and citations.
And, of course, the agenda of the government is to increase revenue due to fines:
A 2001 paper by the Office of the Majority Leader of the U.S. House of Representatives reported that red-light cameras are “a hidden tax levied on motorists.” The report came to the same conclusions that all of the other valid studies have, that red-light cameras are associated with increased crashes and that the timings at yellow lights are often set too short to increase tickets for red-light running. That’s right, the state actually tampers with the yellow light settings to make them shorter, and more likely to turn red as you’re driving through them.
In fact, six U.S. cities have been found guilty of shortening the yellow light cycles below what is allowed by law on intersections equipped with cameras meant to catch red-light runners. Those local governments have completely ignored the safety benefit of increasing the yellow light time and decided to install red-light cameras, shorten the yellow light duration, and collect the profits instead.
The cities in question include Union City, CA, Dallas and Lubbock, TX, Nashville and Chattanooga, TN, and Springfield, MO, according to Motorists.org, which collected information from reports from around the country.
Speed Cameras Record Every Car
In this article about British speed cameras, and a trick to avoid them that does not work, is this sentence:
As vehicles pass between the entry and exit camera points their number plates are digitally recorded, whether speeding or not.
Without knowing more, I can guarantee that those records are kept forever.
EDITED TO ADD (7/25): As pointed out by Pete Darby in comments: Passenger moons speeding camera and gets his picture published even though the car was not speeding.
Police may take action against the man for public order offences and not wearing a seat belt.
Officers have the registration of the car, which was not breaking the speed limit, and intend to contact its owner.
It is understood the driver will not face prosecution as no driving offence was being committed.
How did they even know to look at the picture in the first place?
SQL Injection Attacks Against Automatic License Plate Scanners
This picture is almost certainly Photoshopped, and a joke, but it’s certainly a clever idea. As automatic license plate scanners become more common, why not get a SQL injection attack as a plate?
Reminds me of this xkcd cartoon.
Seat Belt Usage and Compensating Behavior
There is a theory that people have an inherent risk thermostat that seeks out an optimal level of risk. When something becomes inherently safer—a law is passed requiring motorcycle riders to wear helmets, for example—people compensate by riding more recklessly. I first read this theory in a 1999 paper by John Adams at the University of Reading, although it seems to have originated with Sam Peltzman.
In any case, this paper presents data that contradicts that thesis:
Abstract—This paper investigates the effects of mandatory seat belt laws on driver behavior and traffic fatalities. Using a unique panel data set on seat belt usage in all U.S. jurisdictions, we analyze how such laws, by influencing seat belt use, affect the incidence of traffic fatalities. Allowing for the endogeneity of seat belt usage, we find that such usage decreases overall traffic fatalities. The magnitude of this effect, however, is significantly smaller than the estimate used by the National Highway Traffic Safety Administration. In addition, we do not find significant support for the compensating-behavior theory, which suggests that seat belt use also has an indirect adverse effect on fatalities by encouraging careless driving. Finally, we identify factors, especially the type of enforcement used, that make seat belt laws more effective in increasing seat belt usage.
Tracking Vehicles through Tire Pressure Monitors
Just another example of our surveillance future:
Each wheel of the vehicle transmits a unique ID, easily readable using off-the-shelf receiver. Although the transmitter’s power is very low, the signal is still readable from a fair distance using a good directional antenna.
Remember the paper that discussed how Bluetooth radios in cell phones can be used to track their owners? The problem with TPMS is incomparably bigger, because the lifespan of a typical cell phone is around 2 years and you can turn the Bluetooth radio off in most of them. On the contrary, TPMS cannot be turned off. It comes with a built-in battery that lasts 7 to 10 years, and the battery-less TPMS sensors are ready to hit the market in 2010. It does not matter how long you own the vehicle transportation authorities keep up-to-date information about vehicle ownership.
