while i was going to WyoTech one of my friends purchased a 2009 Mitsu EVO and removed his and reprogrammed a bunch of stuff so he cud modify it how ever he wanted. so im guessing they can be removed or messed with lolI can see the pros, data is collected that could pertain to the investigation of a motor vehicle accident and determine whether it is driver or vehicle error, and exactly what the problem was. I would imagine the data collected is very expansive and very revealing to a collision reconstruction expert.
However, it's also just another "Big Brother" moment where the government yet snakes there way into another aspect of our lives. I mean, technically if you have nothing to hide then this whole black box thing shouldn't be a problem, in fact it could probably be put to use by civilians if the data wasn't just recording 30 seconds prior to airbags deploying. Several offenses and defenses regarding various traffic violations could be created by these black boxes. Your car could be used for you, or against you.
Now I'm interested in GM's prior use of these, and exactly how many models and cars these boxes are in. I also would like to know how tamper proof the system is. Not to sound like some crazy conspiracy theorist but I would hope the system is impenetrable by foreign sources.
They can be useful. An old friend of mine had a late 89 or 90 Lumina I believe that was involved in a very serious wreck. The police learned that the car had the black box and contacted GM about pulling it and downloading the readings from it. GM contacted my friend with in just days and by the end of the week they had sent a representative to pull it and gather the information. They were amazed that he and his passenger survived the wreck. The black box also showed that he was not the cause of the accident. GM even bought the car from him to study how it performed during the collision. His passenger was fine and my friend had some bruising from the collision and the car was fully totaled out.If I understand this correctly, all GM vehicles 1990+ have one already, but the Gov. is planning to mandate on ALL vehicles.
Good thread. My take is that the block box is merely an IC in one of the main computers (PCM, BCM, etc). In recent years, flash memory has gotten very dense and very inexpensive. The write times are reasonably fast - that is, it can store data in real time. And getting a megabyte is cheap. So, for example, the last million data points logged by a car could be stored there. That data can includes lots of different things - speed, TPS, brake pedal position rpm, etc. And, depending on how the data set is managed, it could include data from minutes, hours days, weeks or longer. IOW, every detail, every subtle nuance of driving style, can be learned from such a device.^I think the article said they could be under the center console, but since some Imps got the bench, I would think elsewhere on all?
"Those that would trade their freedom for security, deserve neither" - Benjamin Franklin, (I believe).honestly I would like that just because it could save my ass in terms of $$$ if someone hit me. Still sucks that the government has another way to get too involved but i think the benefit outweighs that problem.
