Reports that Tesla withheld key details about a fatal Arizona crash involving its automated driving technology underscore the need for greater transparency from every company testing or operating these systems on public streets, according to traffic safety attorney Amy Witherite, founder of Witherite Law Group.

The crash occurred around 3 a.m. on Oct. 31, 2025, as a Tesla Model 3 traveled east on Loop 202 in Mesa, Arizona. According to news reports citing a filing with the National Highway Traffic Safety Administration, the Tesla came to a sudden and unexplained stop in an active freeway travel lane while an automated driving system was verified as engaged. A Ford F-350 then struck the Tesla from behind, killing the Tesla driver. Tesla reportedly treated the crash narrative, software version and information about whether the vehicle was within its approved operating area as confidential business information.

Federal regulators have also questioned the timeliness and completeness of Tesla’s crash reporting. In August 2025, NHTSA opened a formal reporting audit to determine whether incidents remained unreported and whether Tesla’s submissions contained all required and available information.

“The public deserves more than broad claims about miles driven or overall accident statistics,” Witherite said. “Those numbers do not tell us how these systems perform in specific, dangerous situations or why a vehicle made a decision that may have contributed to a crash. If a company wants to use public streets to develop and operate this technology, it has a responsibility to be open about safety failures.”

Witherite said legitimate intellectual property should be protected, but trade secret claims should not become a blanket justification for withholding information needed to understand a serious injury or death.

“Tesla makes no secret of its desire to keep critical safety information out of public view,” Witherite said. “In a March 2026 filing covering eight incidents, Tesla told NHTSA that it considers the marked information ‘wholly confidential and proprietary’ and asked that it remain confidential ‘in perpetuity.’ That may serve the company’s interests, but it does not serve the public interest when people are being injured or killed.” Read Tesla’s confidentiality request.

“We need meaningful disclosure of what the vehicle detected, what the software decided, whether warnings were issued and what the human driver was expected to do,” Witherite said. “Regulators, safety researchers, first responders and the public need that information to determine whether a problem is isolated or part of a broader pattern.”

People involved in crashes with automated or partially automated vehicles may also face an information imbalance because the manufacturer can possess video, telematics, software records and event data that are not readily available to the drivers and families affected.

“Anyone involved in one of these crashes should understand that obtaining the complete record may require prompt legal action to preserve and secure evidence,” Witherite said. “Families should not have to fight through layers of secrecy to learn why a vehicle behaved as it did.”
