Robotaxi commercialization encounters regulatory obstacles: Tesla, Inc. (TSLA.US) deadly car accident in Texas renews FSD safety controversy, NHTSA launches new investigation.

The U.S. National Highway Traffic Safety Administration (NHTSA) announced on Monday that a special investigation has been launched into a fatal collision involving a Tesla, Inc. Model 3. The accident occurred on the evening of June 19th, when a Tesla Model 3 crashed through a brick house in Katy, Texas, causing 76-year-old Martha Avila, who was inside the house, to be airlifted to the hospital and later died. This accident quickly became a focus of controversy surrounding Tesla, Inc.'s Autopilot and Full Self-Driving (FSD) assisted driving systems. The driver, Michael Butler, told the Harris County Sheriff's Office that the vehicle was in Autopilot mode at the time of the accident. However, Tesla, Inc. broke its silence on Monday and provided a statement that contradicted the driver's account. Accident details: high-speed collision with residential house at 73 mph According to the Harris County Sheriff's Office, the accident occurred on the evening of June 19th. A Tesla Model 3 failed to turn right at an intersection, continued at high speed and crashed into a house in a suburb of Houston. Video footage shows the vehicle speeding through the front yard of the brick house and crashing into the front hall. After the collision, the vehicle was embedded deep inside the house, surrounded by broken plaster, fractured beams, and furniture debris. Driver Butler is cooperating with the investigation at the scene, and the police report states that he was not under the influence of alcohol and cooperating with the investigation. Butler told the sheriff's deputy that the vehicle was in Autopilot mode at the time of the accident. The Harris County Sheriff's Office stated that the investigation results will be submitted to the local district attorney after evidence collection is complete to determine if criminal charges should be filed. Two accounts: driver claims "Autopilot engaged", Tesla, Inc. refutes "driver press accelerator to the floor" Butler told the police that the vehicle was in Autopilot mode at the time of the accident. This detail was quickly picked up by multiple media outlets and became a focal point of public debate over the weekend. Investigators have not independently verified the driver's claim about Autopilot being activated, nor have they confirmed whether the system involved was the basic version of Autopilot or "FSD (Supervised)." Sergeant Taman, the accident investigator from the Harris County Sheriff's Office, said, "We are conducting a thorough investigation, and this will be the core focus of the investigation." Tesla, Inc. provided a completely different account. Ashok Elluswamy, Vice President of AI Software at Tesla, Inc. and the first engineer hired for the Autopilot team in 2014, posted on X with a different account based on system data logs: "In this accident, the driver pressed the accelerator pedal to 100% in a residential area, manually overriding the autonomous driving system. The collision occurred at a speed of 73 miles per hour, and the accelerator pedal was still pressed down even after the collision." Elluswamy stated that the accident was due to human accelerationregardless of what system may have been activated at the time, the responsibility for everything that followed lies with the driver pressing the accelerator to the floor, and not the vehicle itself. Tesla, Inc. CEO Elon Musk later echoed and emphasized this viewpoint on X: "These accusations are completely baseless. FSD drives slowly on community streets, and this was a high-speed collision!" Musk's statement aimed to shift the public's focus from "system malfunction" to "human misuse or improper operation." Currently, the claims of the driver and the statements of Tesla, Inc. executives are still under investigation and have not been independently verified. Regulatory background: NHTSA special investigations exceed 40, FSD faces engineering analysis NHTSA confirmed on Monday that a "special accident investigation" has been initiated into this incident. Reportedly, this is the latest of more than 40 such investigations launched by the agency in recent years into Tesla, Inc. accidents involving advanced driver assistance systems. Since Tesla, Inc.'s "advanced driver assistance system" became a standard feature on new vehicles in 2016, NHTSA has investigated over 36 specific crashes involving the system. According to the Associated Press, in the past decade, NHTSA has launched 46 special crash investigations involving Tesla, Inc.'s autonomous driving or driver assistance technology. In over a dozen of these accidents, at least one persondriver, passenger, or pedestrianwas killed. Additional regulatory pressure comes from another front: in October 2025, NHTSA initiated an investigation into approximately 2.9 million vehicles equipped with the FSD system from Tesla, Inc., with issues including running red lights, driving in reverse, and more. In March 2026, this investigation was upgraded to an engineering analysisthis is the final step before initiating a vehicle recall. NHTSA also launched a separate investigation into Tesla, Inc. for allegedly failing to report Autopilot and FSD accidents as required by regulations. Whether the Autopilot system was truly activated at the time of the accident, whether it was manually overridden by the driver, or experienced a malfunction, will need to be determined after a comprehensive review of the vehicle's data logs by investigators. Historical concerns: data disputes and 65 fatal accidents Tesla, Inc.'s history of disclosing accident data adds extra complexity to this investigation. Previous reports have indicated that Tesla, Inc. has repeatedly lost, withheld, or obstructed access to comprehensive electronic data generated and stored by its vehicles in severe collision incidents. Tesla, Inc. engineers admitted in court last year that the company did not retain complete Autopilot accident records in the first three years after the system went online. The independent website TeslaDeaths.com tracks collision incidents involving Tesla, Inc. vehicles as relevant factors based on news reports, police records, and federal data. The website found that between 2013 and 2025, at least 65 fatal accidents involving Tesla, Inc.'s Autopilot or FSD (Supervised) systems were considered as contributing factors. Recent similar accidents have been frequent: in May 2026, a Tesla, Inc. crashed into a house in Claremont, California, after colliding with another vehicle, injuring six people. Witnesses reported that the driver claimed to be using Autopilot at the time. Additionally, in the same month, a fatal accident occurred in Pasco County, Florida, involving a Model Y that veered off the lane and collided with a distribution box before sinking into a pond, resulting in the death of the 87-year-old driver. Both recent accidents involved the Autopilot system's loss of control in relatively simple road conditions, raising concerns about the system's perception of road boundaries and fixed obstacles. Coincidental timing: FSD at a critical moment in commercialization The timing of this investigation is sensitive for Tesla, Inc. Elon Musk is currently pushing forward with the commercial deployment of autonomous driving taxi services (robotaxis). Reportedly, Tesla, Inc. plans to launch autonomous driving taxi services in multiple U.S. cities this year and invites car owners to put their vehicles into fleet operations. For years, Tesla, Inc. has promised that its technology will be advanced and safe enough to allow the company to quickly operate large-scale autonomous driving taxi fleets on U.S. public roads. However, the latest NHTSA investigation comes at a time when the FSD system is facing the most stringent regulatory scrutiny in history. The numbers from the 3.2 million FSD vehicle engineering analysis phase investigation, the 36 special crash investigations, and the records of 65 fatal accidents are creating increasing tension with the narrative of being the "autonomous driving leader" that Musk has presented. Despite being influenced by federal investigation news, Tesla, Inc.'s stock price rose by 1.14% to $405.05 on Monday. However, prior to this, Tesla, Inc. has been under pressure for three consecutive days due to the tech stock sell-off triggered by a drop in SpaceX's stock price. The market seems to be waiting for the final conclusion of the investigation. On the European front, Tesla, Inc. faces similar scrutiny. According to reports, several independent road safety researchers have pointed out that Tesla, Inc.'s self-reported safety data submitted to the Netherlands and Sweden contains multiple invalid comparisons, essentially constituting "misleading marketing propaganda" aimed at overstating the safety of FSD.
