The missing Malaysian plane and the search for its black box has been in the news for weeks now. But did you know your vehicle has its own black box? I didn't until I read a thread an another forum today. I have edited the post on the other forum below.
If your vehicle is post 1997 AND the manufacturer exports your model into the USA then it's highly likely you have one in your vehicle.
And if you have a fatal or major prang that little box could either help prove your guilt or your innocence.
It might tell them just what you were up to in the last few seconds prior to that prang, just how fast you were driving, were you actually braking, maybe how hard, maybe which way you were pointing the steering wheel and a whole heap of other data about your driving.
Video goes for 53 minutes but I watched it to the end and found it very informative.
