The funny thing is, that if you have purchased a used vehicle from a "buy here pay here" car lot. Then you already have a black box.
If you miss
a payment, your vehicle will become inoperative, and gps location will be given.
Outside of that though, I do not see a purpose. What is that data gonna tell you? Your GPS location. If you have onstar that stuff is already going
on. Besides that, the OBD2 system that has been installed on most vehicles since 1994 can tell you just about anything else.
So to me this is just another reason to run a stand alone fuel management system. The gov has already had there noses into my vehicles for to long.
With emissions, speed limiters, and the likes.
Ultimately though, when it all comes down to it. It will be something that ultimately can be removed, or disabled. I do not care, how hard wired it is
into the pcm. It is always possible to reprogram a pcm, thats why the cars in america are usually so watered down, you have to buy an after market
chip just to get what the vehicle was originally designed to do. If you can't find one, you make one. Or with like the RX-8 you here the term reflash
the pcm. If the device is external there will be ways to confuse it, or send it false signals, or completely bypass the system.
This is not a concern.

a memory chip that record this already just not sure off how far back it goes
sec. or min.
this new box may have GPS a year off data
Electronic ignitions do not have a chip that records anything you do for seconds or minutes.'
To the guy that said he would drive used cars or take the bus......The bus has TSA agents......
Electronic ignitions do not, but the OBD2 system does. In other words, on board diagnostics 2. Now obd1 did not save anything. But the OBD2 system
does record data. I can tap into it with my scanner and tell many many things about the vehicle. Especially if a malfuntion indicator light (MIL) is
on. It has "freeze frame" where it save exactly what was going on for a set time period.
But again I ask why? What else do you want to know? Steering angle? Braking degree? Some of your more advanced vehicles have these. due to
excelerometers (cant spell). And is able to record data if a trigger is set, either a MIL or some other programming within the system. Now does it
save speed? Well do to great things like ABS and traction control. You have wheel speed sensors. And in the freeze frame data it will. You can see
exactly which wheel sensor went bad.
So ya, all this is already available, especially with GPS.
