I know for a fact my Dodge has one, but does anyone have first hand knowledge on whether the LS has something like this ? Watching TV tonight and there was an intersting story. I am sure most have heard of an airplanes "black box", but have you heard of them in automobiles. They do exist. Not exactly little black boxes, but they're called a EDR or Event Data Recorder. Most modern cars like the LS have onboard systems such as airbags, stability control, traction control. These systems monitor data from various sensors and are stored within the computer, much like check engine codes that can be checked later. The "Black Box" can record informational data, such as: engine / vehicle speed (5 seconds before impact), brake status (5 seconds before impact), throttle position(s), and even the state of the driver's seat belt switch (on/off). Here in Florida there is a guy serving 30 yrs in prison for the info obtained from his "black box". If you get into an accident that causes severe or fatal injuries you can most certainly expect for the data from your car to be used against you, your car becomes a crime scene and everything inside, including the computers can be subjected to inspection. I can personally account for this because my wife had an accident earlier this year and her airbag did not deploy which pissed me off, so i started to threaten Daimler Chrysler. They sent a rep. to inspect our car and was able to download data out of my car that suggested that the conditions did not require the airbag to deploy. So that capability is absolutely real. I guess i am posting this for informational purposes and to let anyone know who drives recklessly that you have a silent witness to your driving riding with you at all times. Right now there is debate on whether those systems should be allowed as evidence in court, but the auto makers say that the data collected is as accurate as you can get. Just something to keep in the back of your mind when driving.
