The National Transportation Safety Board (NTSB) has determined that the driver who collided with a Texas residence while driving a Tesla at 70 mph had fully depressed the accelerator.
TL;DR: The NTSB concluded that a driver, not Full Self-Driving (FSD), was responsible for a fatal crash involving a Tesla in Texas, as he fully pressed the accelerator on a residential street. The incident occurred when the Tesla Model 3 was traveling over 70 mph in a 30 mph zone, leading to a collision with a home that resulted in the death of 76-year-old Martha Avila. The driver, Michael Butler, claimed he passed out while using the driver-assistance system, but his search history revealed inquiries about FSD's performance, which raised concerns about his use of the technology. Butler faces manslaughter charges, and Avila's family has filed a wrongful-death suit against him and Tesla.
While the findings exonerate Tesla’s FSD software in this case, they do not address the ongoing scrutiny of the technology. The NHTSA has heightened its investigation into FSD to an engineering analysis stage, examining over three million vehicles after incidents where the system failed to recognize poor visibility conditions. There have been 46 special investigations into Tesla's self-driving technology, with fatal cases documented.
This situation highlights a persistent issue with FSD Supervised, where drivers can override the system by pressing the accelerator—a factor complicated by Tesla’s marketing blurring lines between driver assistance and full autonomy. Following regulatory concerns, Tesla renamed the feature from “Full Self-Driving” to “Full Self-Driving (Supervised)”. The company is facing a class-action lawsuit regarding its FSD advertising from 2016 to 2024.
The NTSB findings coincide with assertions from Tesla’s AI software head, Ashok Elluswamy, that data indicated the driver manually accelerated fully. Tesla claims a lower incidence of major crashes per mile under FSD, yet its robotaxi fleet has experienced crashes at a rate four times higher than the average of human drivers. Additionally, the NHTSA is investigating 58 incidents of Teslas allegedly breaking traffic laws while using self-driving tech, resulting in multiple crashes and injuries.
The timing poses challenges for Tesla as Elon Musk plans to transition many Teslas to fully autonomous vehicles and has begun marketing Cybercabs without traditional controls. Upcoming second-quarter earnings reports are anticipated to show a sixth straight quarter of stagnant or declining profits, with Tesla's stock trading at a high multiple compared to the S&P 500 average, reflecting more on investor optimism about future autonomous driving rather than current performance.
