Tesla’s closely-guarded driving data has been decrypted for the primary time, in response to a Dutch government-run forensic lab. The Netherlands Forensic Institute (NFI) stated it discovered a wealth of details about Tesla’s Autopilot, together with data round pace, accelerator pedal positions, steering wheel angle and extra. The findings will permit the government to “request more targeted data” to assist decide the reason for accidents, the investigators stated. 

The researchers already knew that Tesla autos encrypt and retailer accident associated data, however not which data and the way a lot. As such, they reverse-engineered the system and succeeded in “obtaining data from the models S, Y, X and 3,” which they described in a paper offered at an accident evaluation convention.

These data comprise a wealth of knowledge for forensic investigators and site visitors accident analysts and can assist with a prison investigation after a deadly site visitors accident or an accident with harm. 

With information of tips on how to decrypt the storage, the NFI carried out checks with a Tesla Model S so it may evaluate the logs with real-world data. It discovered that the automobile logs have been “very accurate,” with deviations lower than 1 km/h (about 0.6 MPH).

The NSI additionally analyzed a number of accidents utilizing the uncooked data it acquired. In one case, a Tesla on Autopilot collided with a automobile forward that instantly braked. Normally, if the Autopilot does not brake in time, the driving force is meant to take over.  

“In this case, the investigation showed that the driver did indeed intervene and also within the expected response time,” stated researcher Aart Spek. “The fact that it turned out to be a collision was because the following distance [chosen by Autopilot] was too tight in the busy traffic situation. That makes it interesting, because who is responsible for the following distance: the car or the driver?” 

It was once potential to extract Autopilot data from Tesla EVs, however it’s now encrypted in latest fashions, the investigators stated. Tesla encrypts data for good purpose, they acknowledged, together with defending its personal IP from different producers and guarding a driver’s privateness. It additionally famous that the company does present particular data to authorities and investigators if requested.

However, the crew stated that the additional data they extracted would permit for extra detailed accident investigations, “especially into the role of driver assistance systems.” It added that it could be preferrred to know if different producers saved the identical degree of element over lengthy durations of time. “If we would know better which data car manufacturers all store, we can also make more targeted claims through the courts or the Public Prosecution Service,” stated NFI investigator Frances Hoogendijk. “And ultimately that serves the interest of finding the truth after an accident.”
