I've seen a "black box" referred to by the media in the past and again today in the reporting of the death of Aubrey McClendon. The headline on the TV said "Police retrieve the Black Box from vehicle".
Is this a real device or do investigators pull data from the ECU and the media just calls it a "black box"?
If its a discrete device or a part of the ECU, what does it record, and for how long? Is it hardened or fireproof like on an airplane or do investigators just have to hope that it's not damaged?
I've read an updated article saying the vehicle in the McClendon case was a 2013 Chevy Tahoe that was almost completely destroyed by fire.
