Some states limit how the information saved in your car's various data recorders can be used.
 
The NHTSA is being lobbied to develop standard for "Event Data Recorders."
 
Anyone have any personal experience with a black box in your car or think there are privacy concerns with them?

Volvo's have had data recorders for years.
Personally, I don't have any problem with them.
If you are in an accident, they can provide valuable information.

To you, the cops or the lawyers on the other side?

"There have been cases where warranty was denied for blown engines because someone mis-shifted, or used forced induction but then removed it before taking the vehicle to the dealership. So, some information stays in the computer for days if not weeks."
 
These things are based on throwing an exception code in the software, which is different from storing vehicle settings and driving patterns.
 
As some people have already said, the "black boxes" only store a few seconds of data.

Depends who is at fault doesn't it?
Obviously, if you are at fault, it won't help you. It will help your victim.
So, don't cause any accidents

it's possible parameters on the data bus are in error. for example, what if the velocity sensor was bad and the vehicle was registering 0MPH? does that mean the vehicle is stopped?
 
so there would be all sorts of additional analysis and expertise and revealed knowlege about the design of the system and validating the information contained therein that would be needed.

You are talking about something that could only really happen in theory.
If one of the sensors that the black box records does go bad,chances are you would have to have the car towed to the dealer for repair anyway.
those sensors perform functions that are necessary for the car to operate on a daily basis. All the box would do is record their operation.

If it is used to explain a crash and determine who was really at fault, then I'm all for it.
 
If you are trying to avoid prosecution for being the cause of a crash, you can't hide from black box data. I think that's a good tool for the good guys.

not the speedo.
 
and do these recorders record the angular velocity of each wheel?
 
all i'm saying is that proper interpretation would require additional expertise to make sure the data was read and interpreted properly. the group which reads out the digital flight data recorders from planes post crash are a specialized group. you wouldn't want every police department or insurance company responsible for same on automobiles would you?

If they use the ABS sensors,they do.
 
There is NOWHERE near the same amount of data on these recorders as there is on an airplane's.
