[General] vehicle black boxes

[Justin Richards]

This isn't some kind of *illuminati conspiracy*, this is a device that
records the last few seconds of vehicle telemetry, including airbag
deployment info, vehicle speed, brake application time, brake force,
throttle position, accelerometer and roll/yaw data, steering position, etc.

It can be used to determine fault, though it is not enough to truly
determine that, and anyway, 99% of the time, nobody will ever look at it.

It's not something that's open, not because the car manufacturers need to
be protected, but because giving that much raw data to your standard
lay-person, especially after a wreck, is like giving ECG output of a person
having a heart attack to a monkey, and asking the monkey to identify the
person who gave that guy a heart attack. That much raw data is going to
confuse and enrage, and there is also the issue of bias.

If you feel that it is an issue, in the event of a wreck, you can deny law
enforcement access to your OBDII port at the scene of the wreck, and
request they get a warrant for the data, in which case you should become
familiar with the location of the EDR, and destroy it before they get the
warrant, at which point you might get a nice charge of destruction of
evidence.

Otherwise, *go get a vehicle that does not have an EDR.*
