Edr
 

Someone recently told me newer cars have a data recorder build in, just like planes. I told him he is dreaming, but just reading through the manual, it seems to be true. Does that mean in case of an accident even if it was not my fault, the insurance can request the data, and maybe even use it against me, for exemple being over the speed limit, or not breaking hard enough.....?

But of couse it could also help if I am accused of speeding before a crash, can I request the data in such an event, anybody with some more knowledge?


"This vehicle is equipped with an Event
Data Recorder (EDR). The main purpose of
an EDR is to record, in certain crash or near
crash-like situations, such as an air bag
deployment or hitting a road obstacle, data
that will assist in understanding how a
vehicle’s systems performed. The EDR is
designed to record data related to vehicle
dynamics and safety systems for a short
period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to
record such data as:
. 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
depressing the accelerator and/or
brake pedal; and,
. How fast the vehicle was traveling.
. Sounds are not recorded.
These data can help provide a better
understanding of the circumstances in
which crashes and injuries occur. NOTE:
EDR data are recorded by your vehicle only
if a nontrivial crash situation occurs; no
data are recorded by the EDR under
normal driving conditions and no personal
data (e.g. name, gender, age and crash
location) are recorded. However, other
parties, such as law enforcement, could
combine the EDR data with the type of
personally identifying data routinely acquired
during a crash investigation.
To read data recorded by an EDR, special
equipment is required and access to the
vehicle or the EDR is needed. In addition to
the vehicle manufacturer and NISSAN
dealer, other parties, such as law enforcement,
that have the special equipment, can
read the information if they have access to
the vehicle or the EDR."

It varies by state, some allow it to be used in court but not by insurance companies. Meaning they must bring charges against you to view while others do not allow anyone but the manufacture view it.

Yes so slow down and brake harder :driving:

You are talking about the air bag sensor, yes it's always recording. Every new car has one it's mandatory. In the event of an accident law enforcement needs to obtain a search warrant to use the data against you. I have done the above for work. But I only go through the trouble when it's a fatal accident to reconstruct it. It records 5-7 seconds before deployment or non-deployment depends on the make of the car. As far as I know law enforcement is the only one who have the equipment to read the data. Hope it helps you under stand.

I've seen it used mostly in civil court cases. Usually when there is a death or significant bodily injury. They've been on cars dating back to 1997, and their use has been relatively rare given the amount of crashes that have relied on the data.

For Nissan/Infiniti specifically, EDRs are only in 2013+ models. Complete list here:

Edit: to answer your first question, your insurance company would likely need a court order. Second question, you have access to it yourself, it's your car so you "own" the data. (It'd be like you had a deleted text message on your cell phone that could help you in some way, you have every right to take your own phone to some expert or company to try to retrieve the data)
