Police using "blackbox" in deadly Cobalt crash
Just saw on the news a very sad story about two young parents that were killed this morning when their cobalt couple struck a telephone pole. Both were not wearing seatbelts. I cannot find a video on line that said what the live news said, but channel 5 said, authorities have recovered the black box from the vehicle and hopefully this will lead to some answers as to how the crash happened.
Black box? Whats the deal?

The ECU takes a snapshot (has for years) of multiple sensor readings at a moment of impact. Insurance companies use 'em like crazy. The black box thing I believe is just another layer of that which will probably be standard on all cars in a few years

your airbag module also has the ability to store you speed at impack, bracking force etc...but its not something you stick a scanner on and, bam they have all your info

If you guys heard of the insurance company Progressive and their "snapshot" device. That might be just another "blackbox" you put in your car and it tracks all your moves and sends them to your insurance company (for 6 months). That's why they give 30% discount on your policy (or not) depending on how you drive.

There are more... assured ways of disabling it, but that's the easiest. The downside is that the bluetooth is a part of the Onstar module on '09+ cars, so you'll lose that. On some of the cars, the same fuse is also on the XM Radio circuit too, so it'll disable that too if you pull the fuse. So if you don't have/want both the XM and bluetooth, then just pulling the fuse is the easiest method.
It records it in a <30 second loop and when the car hits something and/or airbags deploy then the last information that's naturally available on the loop is also the information leading up to the crash.
It's right in the Owners Manual. They call it the Event Data Recorder ("EDR"). It's on page 7-17 in my manual.
It says right there in the manual that it monitors:
-How various systems in your vehicle were operating
-Whether or not the driver and passenger safety belts were buckled/fastened
-How far, if at all, the driver was pressing the accelerator and/or brake pedal
-How fast the vehicle was travelling
Important: EDR data is recorded by your behicle only if a non-trivial crash situation occurs; no data is recorded by the EDR under normal driving conditions...

It's nothing new and varying amounts of data have been recorded since air bags first started appearing in increasing number of models before they became mandatory. Early air bag control modules were pretty primitive and would record very basic data like vehicle speed, seatbelt usage, and vehicle deceleration for just a few seconds before a collision triggering air bag deployment. Newer vehicles have much greater sensor and data available to the computer and newer controllers have a much longer recording loop and can include data like if the brakes were applied, vehicle speed, lateral and yaw rates, steering angle, seatbelt and occupant sensor data, etc.
Some may view it as "big brother" but what if you or your family got hit and there was data that could prove the other party was at fault? It's not like law enforcement can just pull the data from a car either, and in most cases they have to obtain a search warrant. There are also other benefits the technology can provide like providing valuable real-world crash data automakers can use to improve safety of vehicles.
I can understand the concern about who has access to this data but until the NHTSA implements uniform standards someone needs specialized and expensive scan tools to read this data. Witness the unintended acceleration claims of Toyota models recently where Toyota had to access the data as it wasn't available for third-parties to try to find out what went on. If you're worried about this then don't buy a new car. I'd rather have some personal accountability and know that if I'm not doing anything wrong I have nothing to worry about, and if I do ever make a mistake and am responsible for an accident that's why I carry insurance with high limits to make sure everyone is covered.

they would have, but I put it in my other car and barely drove it.
