Car Glass Rules Could Impair Cell, GPS and Radio Signals In CA

An anonymous reader writes "The California Air Resources Board (CARB) just passed a new regulation that requires glazed glass in automobiles that is supposed to reduce the need to use air conditioning. The catch is that the same properties that block electromagnetic sunlight radiation also block lower frequency electromagnetic radio waves. That means radios, satellite radios, GPS, garage door openers, and cell phones will be severely degraded. Even more surprising is that it requires this glass even for jeeps that have soft covers, plastic windows, and no air conditioning.'"

      The thing is, Jeep (and others, like GEM) are appealing to CARB for a waiver, and will probably get one. It was an oversight, not something deliberate.

      GPS, AM, FM are on different frequencies. You must live a sheltered life and not have had the opportunity to see many antennas and compare them.

      Actually, I worked in military communications, and have *built* AM/FM transmitters and antennas, as well as cellular networks. I can tell you from experience that while they work on different frequencies, it's entirely possible to connect an appropriate antenna to a wiring harness to bring the signal inside what's effectively a Faraday cage.

      Many many passengers talk on cell phones to get directions. Some even answer the driver's cell phone. You must live a sheltered exist with few friends who would do that for you.

      I turn my cell phone off when I'm driving, actually. Probably has something to do with that military background, and that desire to have all of my focus on driving when I get behind the wheel. *shrugs*

      There is a general trend away from purpose built GPS navigators and toward GPS applications on smart phones. You must live a sheltered life with little contact with the technical world.

      See above. And you must have lived a very sheltered life to have not come in contact with cars that have in-dash navigation systems....

      Low-E glass was introduced in 1979. I.e., any patents that may have been around for it at the time no longer exist.

      There probably are "newer, better" types of Low-E glass that are still patented, but Low-E glass in general is not.

    and see the nice little FAQ they have. http://www.arb.ca.gov/html/coolcarsfaq.pdf Will my GPS still work? Yes. Many automobile manufacturers currently equip their vehicles with external antennas to ensure proper functioning of factory installed GPS devices. For aftermarket GPS devices, deletion windows, or areas without reflective coatings, will be created in the windshield and the location of these windows noted in the owner’s manual. ARB tests showed that placing the GPS device or the external antenna within the deletion window allows the device to operate as effectively as in a car with no reflective glass.

    The private sector could easily do something this stupid.

    The private sector is already doing something much more stupid - namely, failing to use this glass for the 99% of car windows for which it makes sense. By comparison, requiring it in the 1% of cases (Jeep windows!) where it's not necessary is a little unfortunate but insignificant.

    So, according to the computer, it's better to use A/C with windows up.

    This was too quick and easy for TV, so they decided to stage a seven hour marathon, race-til-you're-empty duel, with Jamie driving an SUV with A/C on and Adam driving an SUV with windows down. Though, once the safety inspector intervened, it was no longer a seven-hour marathon, it was a bit slower (45mph instead of 55mph), and a lot shorter (only 5 gallons each).

    Jamie's A/C car ran out of gas first -- Adam's windows down SUV ran for another 30 laps -- completely contradicting the computer mpg estimate. Computer estimate based on air flow into the engine, so it would appear that it is unable to properly model the difference between A/C and windows down.

    However, often the mythbusters' methodology is shaky, and from this short synopsis (I haven't seen that episode) this was one of those cases.

    At 45 mph you will indeed get better mileage with the windows down (on most cars, YMMV). That's the first methodology fault. The faster you go, the more pronounced the drag. Under 40 you're better with the windows down, over 50 you're better off with them up. Nobody drives 45 on the interstate -- in fact, that's the minimum speed on most highways.

    The second is, you have two different drivers with two different driving styles. The one who is able to keep closer to a steady speed is going to get the best mileage. If they had set the cruise control to 70mph and done the test, the computer would have matched the results.

    "what we call a "Nanny State." That's a Bad Thing."

    Why? A political catchphrase is not an argument, nor is it a description of an actually-existing thing. It's just a shout with no verbal content.

    Think about this: real nannies exist for a reason. Real states also exist for a reason. There are certain situations where people collectively come to the decision that they don't *want* to tolerate certain types of destructive behaviour, because they cost us all. Any healthy group does this, because normal healthy humans are social creatures. We *like* to modify our behaviour so that it doesn't have stupid outcomes for the group. We call this "learning to socialise". The only people who think that a human must be an absolutely self-sufficient, take-nothing, give-nothing, hardcore screw-my-neighbour loner, are psychologically damaged individuals who haven't learned how to live with others.

    It's one thing that such a syndrome exists. It's another that this psychological dysfunction has become a hugely powerful political movement. We don't need to bow down to this false idea of the heroic egotist fighting the mass of zombie sheeple trying to crush his freedom. Instead, look at each case on its merits and realise that collective problems do exist, society is not a bad thing, and that centralised responses sometimes are the right response and sometimes aren't.

    So instead of just throwing a content-free slogan around, how about arguing why in *this* specific case, *this* kind of regulation is the wrong response to a serious societal problem?
