Comment on Tesla withheld data, lied, and misdirected police and plaintiffs to avoid blame in Autopilot crash
Shanedino@lemmy.world 2 months agoIt is possible that the data is just never saved in non-volatile memory meaning that once power is lost that the values are also lost. In which case its not really deleting the information but rather just that information is just never intentionally saved.
P.S. I am not a tesla fan boy just wanted to give this tiny insight.
This explanation is completely fabricated, based on nothing, and nonsense.
It is obviously critical data that nobody halfway competent would write to ram. Also video data is very large and makes no sense to store in ram.
Furthermore the article says it was deleted and they later recovered it which would not have been possible with RAM
Basically why are you pushing this drivel.
If the data is temporarily stored until it is transmitted and then is not considered to be needed anymore I see no reason as to why that would need to be stored locally forever.
Because it may not be possible to transmit depending on location.
On embedded controllers you are usually heavily limited with nonvolatile memory.
Perhaps most importantly although we know it was not so lost because we read the article or at least the summary if it had been it would have been a deliberate design decision to have it be so.
Your explanation doesn’t wash in reality but it also doesn’t wash even in theory.
You’re also making assumptions in that the volatile memory lost power and thus must have been cleared at some point. I dont think there is a right or a wrong based on the knowledge i have I just am throwing out a random guess.
Hell, it could be that this is private information about the driver and the car’s probably gonna end up in a Copart auction after insurance is done with it, so in a way they’re protecting PII.
I doubt they’re doing a full OS wipe when an accident occurs. So PII data would still be on there.
Just stuff you voluntarily save if the crash data is in RAM only. RAM gets autowiped.
What PII is there? It’s a fucking dash cam video, it’s not my blood results from my annual checkup.
Full address via recordings of where you live would be PII
Yeah, this is a good point. Also, another comment said it’s possible the data snapshot is very large, so it’s not intended to be stored locally.
Either way, if you are sending data about my car to a server, it better be easy for me to get this data if needed.
Don’t these keep a video record of every time a squirrel gets too close to the parked car?
Another m.2 under the dash isn’t going to kill the electric vehicles battery, this isn’t an excuse.
those are saved on external drives. That being said, they could also have it set to save something like this to the external storage if it was too large for the internal memory as well.

Forensic analysis managed to retrieve this data, so it must have been stored in non-volatile memory.

Didnt the article say the retrieved the filename and hash, thus proving the existence of the crash diagnostic snapshot. After which Tesla handed over their copy?
Or did the forensics retrieve the actual data?

The article kind of fumbles the wording and creates confusion. There are, however, some passages that indicate to me that the actual data was recovered. All of the following are taking about the NAND flash memory.
It seems that maybe the .tar file itself was not recovered, but all the data about the crash was still there.
