In an incident that was horrific beyond words, late last month, a stunned family watched in horror as a car plowed into the Katy, Texas home of a 76-year-old mother and grandmother, killing her. The driver has been charged with manslaughter.

In the aftermath of the crash, it emerged that the car in question was a Tesla, and that the driver was making use of full self-driving mode (FSD) around the time the crash occurred. The victim’s family has named Tesla and the driver as defendants in a lawsuit. But per Electrek, Tesla was able to view crash data very quickly after the incident, and the head of AI at the company, Ashok Elluswamy, said the driver “manually overrode self-driving by pressing the accelerator all the way to 100% of the accel pedal in this residential area.”

In the days after the crash, Tesla fans took issue with coverage that characterized the car as in FSD when the crash occurred. CEO Elon Musk seemed to agree, replying to a post, “Yes, this makes no sense. FSD drives slowly through neighborhood streets and this was a high speed crash!”

But Musk seems to be assuming bad faith, as if coverage implied FSD had suddenly shifted into, perhaps, some kind of previously unannounced homicidal maniac mode and attacked a house. If anyone was saying this is what happened, they should apologize. It’s clearly not what happened.

And on Wednesday, the National Transportation Safety Board (NTSB) largely confirmed Tesla’s version of events. Their report reads, in part:

“Electronic data recovered from the vehicle indicated that before the crash, the driver manually overrode FSD (Supervised) by pressing the accelerator pedal to 100%, and the vehicle’s speed was greater than 70 mph when the crash occurred.”

But cooler heads had noted weeks earlier that, like with good old fashioned cruise control, accelerating doesn’t boot you from FSD. The car takes the input, and stays in FSD. The question isn’t one of mechanics and technology, but one of philosophy: if FSD is meant to be “driving” when someone jams on the accelerator in a residential area, FSD may not be the “driver” in one important sense, but the car was still in FSD mode.

Because as much as Tesla would probably like FSD to be a total non-factor in the incident, that may not be the case either.

ABC News noted that, according to court documents, the driver claimed he “passed out” with the car in FSD on the highway, and that’s the last thing he remembers before the crash. He says he wasn’t sick, and medical records show no seizures, cardiac episodes, drugs, or alcohol.

A local Fox affiliate says records show the car was making deliveries for DoorDash while in FSD in the “hours and minutes leading up to the crash.” While in a neighborhood, it apparently signaled it was going to turn left onto one street, but instead the pedal went to the metal. This took the Tesla onto the victim’s cul-de-sac instead, and put it on its fateful collision course with her house.

To make matters weirder, other court records now show, per Electrek, that the driver had Googled the terms, “Tesla fsd not aggressive enough 2026,” “FSD is not aggressive enough for city driving,” and “Tesla fsd too timid.” That’s the kind of thing you Google when you’re looking for a Reddit post from someone sharing your consumer gripe.

In any case, the odds aren’t good that the driver wanted this to happen, nor that Tesla programmed its cars with evil intent. But FSD was being used around the time of this unusual fatal incident, and the public deserves to know more. Fortunately, a lot more will come out as the lawsuit progresses.
