Hacks: Dutch Lab Decrypts Tesla Vehicle Data Storage

[grarpamp]

All vehicles should destroy data
after every few drive cycles or trips,
let users choose. Otherwise vehicle
refits will and should appear on free market
to provide that, just raw motor and battery,
no computer storage or anything else needed.


Dutch Government Lab Decrypts Tesla's Data Storage System, Finds "Far
More Data Than Previously Aware Of"

We may soon find out whether or not Tesla has been deceptive in
presenting its driver data.

According to Reuters, a Dutch government's forensic lab says it has
decrypted the car's data-storage system, which has uncovered "a wealth
of information that could be used to investigate serious accidents."
But the best part: the Netherlands Forensic Institute (NFI) says it
has found "far more data than investigators had previously been aware
of".

How unexpected.

The NFI said that the decrypted data proved that Tesla stores
information about Autopilot usage, speed, accelerator pedal position,
steering wheel angle and brake usage. Some of the data can be
available for over a year, the report says.

Francis Hoogendijk, a digital investigator at the NFI, said: “These
data contain a wealth of information for forensic investigators and
traffic accident analysts and can help with a criminal investigation
after a fatal traffic accident or an accident with injury."

For example, one investigation took place when the NFI looked into a
collision involving a Tesla using Autopilot behind a car that braked
hard. The investigation showed that the driver of the Tesla reacted
with the expected response time, but the collision happened because
the Tesla was too close.

Aart Spek, NFI investigator, told Reuters: "That makes it interesting,
because who is responsible for the following distance: the car or the
driver?"

The lab said it decided to forego seeking the data from Tesla in favor
of reverse engineering data logs for it. The NFI said it was “in order
to objectively investigate them," which we're guessing is a kind way
to say "side-step Elon Musk's bullshit".

Data storage has been in question since Tesla announced earlier this
year it had established a site in China to help store data. Tesla
provides data in the Netherlands when a court orders it to do so, but
now the NFI knows exactly what kind of data the carmaker is storing
and for how long.

“You cannot claim what you do not know, so it’s helpful that we now
know what else is being stored,” the NFI said.

"Tesla however only supplies a specific subset of signals, only the
ones requested, for a specific timeframe, whereas the log files
contain all the recorded signals," the institute added.

We're sure this revelation will catch the ear of the NHTSA, who is in
the midst of a broad 700,000+ vehicle investigation into Tesla's
Autopilot and its potential involvement in accidents involving
emergency vehicles.
