A workforce of Dutch forensic researchers have decrypted Tesla’s knowledge storage system, offering entry to a trove of data that may very well be helpful in crash investigations. (The information was first reported by Reuters.)
It’s no secret that Tesla information details about its clients’ driving habits, each to enhance its superior driver help system, Autopilot, and in addition within the occasion of a crash, to offer to investigators.
However researchers on the Netherlands Forensic Institute (NFI) discovered that Tesla’s autos retailer much more detailed knowledge than beforehand recognized, together with pace, accelerator pedal place, steering wheel angle, and brake utilization. A few of this knowledge might be saved for as much as a 12 months, the institute mentioned.
The workforce was investigating a crash involving a Tesla with Autopilot in use that had rear-ended one other car after it braked unexpectedly. Reasonably than search the info from Tesla, the Dutch investigators selected to “reverse engineer” the corporate’s knowledge logs with the intention to “objectively” assess them.
“These knowledge comprise a wealth of data for forensic investigators and site visitors accident analysts and can assist with a legal investigation after a deadly site visitors accident or an accident with harm,” Francis Hoogendijk, a digital investigator on the NFI, mentioned in a press release.
The NFI mentioned that although Tesla has complied with knowledge requests from the federal government previously, the corporate additionally unnoticed a variety of knowledge that would have confirmed helpful. “Tesla nevertheless solely provides a particular subset of alerts, solely those requested, for a particular timeframe, whereas the log information comprise all of the recorded alerts,” the NFI’s report mentioned.
The information of the hack might have implications for US investigators who’re probing a dozen incidents of crashes involving Tesla autos and emergency autos whereas Autopilot is in use. A spokesperson for the Nationwide Traffics Freeway Security Administration didn’t instantly reply to a request for remark.
Tesla encrypts its knowledge to guard it from rival producers. Tesla house owners can request their very own knowledge from the corporate, together with digicam footage, within the occasion of a crash. Tesla additionally runs Autopilot in one thing it calls “shadow mode” that permits the corporate to collect statistical knowledge on false positives and false negatives. In shadow mode, the automobile isn’t taking any motion, but it surely registers when it will have taken motion — which permits the corporate’s engineering workforce to see if the autonomous mode would have averted crashes after they happen.
The Dutch workforce mentioned it was useful to have a broader scope of information from Tesla’s autos, particularly as vehicles grow to be extra like different digital merchandise with the flexibility to log and retailer vital info.
“It might be good if this knowledge would grow to be obtainable extra usually for forensic investigations,” Hoogendijk mentioned. “Now that we all know what sort of knowledge might be obtained from a Tesla, sure knowledge might be requested much more particularly for the aim of discovering the reality after an accident.”
Tesla didn’t reply to a request for remark. The corporate dissolved its press workplace and hasn’t responded to media inquiries in over two years.
