The Netherlands Forensic Institute (NFI) said it had “reverse engineered” Tesla’s vehicle data logs to extract information stored in vehicles.
The Dutch government’s forensic lab said on Thursday it had deciphered automaker Tesla’s electric vehicle driving data storage system, Reuters reported on Thursday. The uncovered data contains a wealth of information that could be used to investigate serious crashes involving Tesla vehicles.
Tesla chief executive Elon Musk has been reluctant to share his vehicle data with regulators, especially after crashes involving the highway driving systems of Tesla’s automaker Autopilot. Tesla’s electric vehicles store detailed data on accidents and other events, which Tesla says is intended for its own internal data analysis.
The Netherlands Forensic Institute (NFI) said it had “reverse engineered” Tesla’s vehicle data logs to extract information stored in vehicles. The NFI said it was “in order to objectively investigate them.”
The Dutch lab said it discovered a lot more data than investigators had previously, according to the Reuters report.
Decrypted data collected by the NFI showed that Tesla was storing detailed information about how the autopilot worked. In addition, vehicles also record speed, accelerator pedal position, steering wheel angle and brake pedal usage, and depending on vehicle usage, this data can be stored for more than ‘a year, according to the Reuters report.
“These data contain a wealth of information for forensic investigators and traffic accident analysts and can aid in a criminal investigation after a fatal traffic accident or an accident with injuries,” said Francis Hoogendijk, investigator digital to the NFI, in a statement to Reuters. .
The NFI said it investigated a collision involving a Tesla driver using autopilot after the vehicle in front of him suddenly stopped, resulting in a collision.
The investigation showed that the Tesla driver reacted within the expected response time to a warning to regain control of the car, but the NFO said the collision occurred because the Tesla was following too closely. other vehicle in heavy traffic while operating on autopilot.
This raises the important question of who exactly is at fault, Tesla or the tailgating driver, NFI investigator Aart Spek explained.
The NFI said Tesla is encrypting its coded driving data to protect its technology from other manufacturers and protect driver privacy, which is understandable. However, Tesla owners can still request their vehicle data, including camera images, in the event of an accident.
Tesla was criticized earlier this year by regulators in China for how it handles data collected from its vehicles, including the external cameras used for Tesla’s “sentry mode,” which allows Tesla owners to monitor their vehicles remotely if someone tries to break in. .
In March, the military banned Tesla cars from entering its complexes in China, citing security concerns over the cameras in its vehicles. Musk said Sentry Mode cameras are disabled in the vehicles it sells in China.
To Tesla’s credit, the NFI said the company complied with Dutch authorities’ data requests, but said Tesla deliberately left out a lot more data that could be useful.
“Tesla, however, only provides a specific subset of signals, only those requested, for a specific period, while the log files contain all of the recorded signals,” the NFI report said.
By cracking Tesla’s code, the NFI now knows more about what type of data the automaker stores and for how long, allowing more detailed data requests, Hoogendijk said.
The NFI said it obtained data from the mainstream Tesla Models S, Y, X and Model 3 and shared the results at a European Association for Accident Research conference for other crash analysts can use them.
Tesla also has remote access to data, the lab said, which is periodically downloaded from cars and used by the company to improve products or correct software errors.
Tesla has recently come under pressure to share more data on its vehicles with investigators in the United States. In August, the National Highway Traffic Safety Administration (NHTSA) identified the 12th accident involving a police or fire department vehicle while a Tesla driver was using autopilot.
Shortly after, the NHTSA opened an official safety investigation into Tesla’s autopilot system in 765,000 US vehicles after a series of crashes. The NHTSA said its investigation “will assess the technologies and methods used to monitor, assist and enforce driver engagement in the task of dynamic driving during autopilot operation.”
As more vehicles like Tesla’s hit the market and are able to store driver and vehicle data and send it back to the automaker, additional concerns about the amount of that data that automakers are having are growing. willing or required to share will certainly be raised, especially in the event of an accident while using automated driving functions.
