NTSB Prelim Report on fatal Tesla Model X crash: 8-seconds before impact
The National Transportation Safety Board has issued a preliminary report on the tragic Tesla Model X crash near Mountain View, CA in March. The NTSB’s preliminary report provided details about the circumstances leading up the accident, as well as observations about the all-electric SUV’s battery pack five days after the crash.
According to the NTSB, preliminary recorded data revealed that the Tesla Model X had its Autopilot engaged with Traffic-Aware Cruise Control set to 75 mph at the time of the accident. The vehicle collided into the crash attenuator, rotating it counterclockwise, removing the front part of the vehicle, and causing subsequent collisions with a 2010 Mazda 3 and a 2017 Audi A4. The NTSB noted that the vehicle’s performance data revealed the following.

- Autopilot was engaged on four separate occasions during the 32-minute trip. The driver-assist feature was engaged for the last 18 minutes 55 seconds before the collision.
- During the 18 minute, 55-second period, the Model X provided two visual and one auditory alert advising the driver to place his hands on the car’s steering wheel. The alerts were triggered more than 15 minutes prior to the accident.
- For the last 6 seconds before the collision, the Model X’s driver did not have his hands on the steering wheel.
- At 8 seconds before the crash, the Model X was following a lead vehicle at about 65 mph. At 7 seconds, the Model X began moving left while still following a lead vehicle. At 4 seconds, the Tesla was no longer following a car. At 3 seconds before the accident, the Model X’s speed increased from 62 mph to 70.8 mph. The vehicle’s emergency braking and evasive steering did not engage.
- During the collision sequence, the Model X’s lithium-ion battery was breached, causing a fire. The flames were extinguished after the Mountain View Fire Department applied about 200 gallons of water and foam during a period of fewer than 10 minutes. In the afternoon, the battery emanated smoke and audible venting was heard, though no flames were observed.
- On March 28, 5 days after the accident, the Model X’s battery pack reignited. The San Mateo Fire Department extinguished the fire.
The NTSB noted in its preliminary report that it is continuing work with the California Highway Patrol and the California Department of Transportation in investigating the accident. The NTSB stated that all aspects of the crash remain under investigation, and that it intends to issue safety recommendations to prevent similar incidents from taking place.
Tesla and the NTSB initially worked together in investigating the fatal Model X accident. The electric car company and the safety board eventually parted ways, however, due to Tesla’s decision to release crash data before the NTSB’s investigation was complete. Among the information Tesla released was that the driver did not have his hands on the wheel during the final 6 seconds leading up to the accident — information that has been reiterated in the NTSB’s preliminary report.
According to a Tesla, it opted to withdraw from its party agreement with the NTSB since collaboration with the safety board prevents the public release of safety information until the investigation was finished. People familiar with the matter, however, noted that the NTSB was the one which opted to terminate its collaboration with Tesla, according to a Bloomberg report.
In an update after the accident, Tesla highlighted that the absence of a crash attenuator — a highway safety device designed to absorb the impact of a collision — was already damaged when the Model X collided with the concrete barrier. In a statement to ABC7 News, Wil Huang, the brother of the ill-fated Model X driver, noted that a working crash attenuator would have saved his brother’s life. Later statements from CalTrans revealed that safety device had been left unrepaired for 11 days before the tragic Model X accident.
Tesla has quietly opened a public interest form for companies that want to buy fleets of its purpose-built Cybercab robotaxis, marking the first official channel for commercial purchases of the two-seat autonomous vehicle. The form went live on September 3, the same day Tesla hosted an invite-only Cybercab launch event in Austin, Texas.
Tesla titled the page “Help Us Build Our Robotaxi Network.” Applicants provide name, email, phone number, company name, and deployment region. They then select one or more categories: Cybercab fleet vehicle purchasing, mobility hubs and infrastructure, event collaboration, or other. Tesla says a representative will follow up with those who express commercial interest.
Tesla has introduced a new form that you can fill out if you are interested in purchasing a fleet of Cybercabs:

Until now, the company had no public ordering path for the vehicle, which was first shown as a concept at the October 2024 “We, Robot” event.
The Cybercab is designed from the ground up for unsupervised operation. It has no steering wheel and no pedals.
Regulatory filings list a 48-kilowatt-hour battery, a single 219-horsepower front motor, a curb weight of 3,113 pounds, and an EPA-adjusted range near 290 to 300 miles. Tesla has already registered dozens of the vehicles with Texas authorities and has been testing them on public streets around Austin.
Tesla Cybercab sightings broaden well outside of Austin with autonomy in focus
The company’s existing Robotaxi service, which currently uses modified Model Y vehicles in parts of Texas and Florida, is expected to add Cybercabs as production ramps up at Gigafactory Texas.
The form signals that Tesla is preparing to treat the Cybercab as more than an in-house fleet asset. Investors and operators have discussed buying groups of the vehicles and placing them on Tesla’s ride-hailing network, with Tesla taking a platform fee. High-profile figures have publicly stated plans to acquire fleets if Tesla allows third-party ownership.
The new page gives those parties a direct way to register interest rather than waiting for a conventional configurator.
Whether the form leads quickly to firm purchase agreements remains unclear. Regulatory approval for widespread unsupervised operation still varies by state, and Tesla has not published pricing or delivery timelines for fleet customers. The company has previously discussed a target price near $25,000 to $30,000 per vehicle.
For now, the form is an early signal that Tesla wants partners to help scale the network rather than operate every Cybercab itself.
Pairing the launch of the Cybercab fleet form with the Austin event is no coincidence. Tesla is inviting businesses to participate in the next phase of its Robotaxi plan at the moment the production vehicle first appears in public.
Tesla has updated its Robotaxi app so riders can pick which vehicle they want before they book. The latest in-app screens now show two options side by side: the two-seat Cybercab and the four-seat Model Y.
A screenshot circulating Thursday shows the change in practice. In Austin, a rider could choose a gold Cybercab for two people or a Model Y for four. Tesla’s updated description calls Cybercab “our first purpose-built autonomous vehicle,” designed for safety, accessibility, and comfort, and says the lineup is available only through the Robotaxi app.
Tesla has updated their Robotaxi page in the App Store. You’ll be able to select if you want a Cybercab or Model Y Robotaxi.

The distinction is more than cosmetic, and it’s important to note that Robotaxi refers to the platform, while Cybercab refers to a vehicle.
Model Y Robotaxis have carried the service since it opened in Austin in mid-2025 and later expanded to Dallas, Houston, and parts of Florida. Those vehicles are converted production SUVs that still have steering wheels and pedals.
Cybercab is different. It has no driver controls, butterfly doors, a low seat height meant to work with wheelchairs, extra trunk space for assistive devices, and braille on the handles. Tesla has registered dozens of the two-seaters with Texas regulators in the days leading up to its September 3 Austin event.
Giving riders a choice lets Tesla match the vehicle to the trip. Most rides involve one or two people, which is where Cybercab is meant to be cheaper and more efficient to operate. Groups of three or four, or anyone who needs more space, can still request a Model Y.
The same app handles booking, payment, cabin settings, and, on Cybercab, features such as phone-based door opening and in-cabin voice controls.
The update does not mean every city suddenly has both cars available. Cybercab support is listed for Austin first, and the purpose-built fleet is still small compared with the existing Model Y roster. Even so, the app change marks a shift from a single-vehicle pilot to a mixed fleet.
Riders can now choose between the compact, purpose-built robotaxi and the familiar SUV that launched the service.
Tesla Cybercab sightings are broadening far and wide, well outside of downtown Austin, Texas, with autonomy in focus as the company plans to launch the all-electric, two-seater this evening in the Lone Star State.
Tesla is set to launch Cybercab to a small group of people this evening in a dedicated event in Austin, Texas. Public details on the event are relatively slim.
However, Tesla’s focus on Cybercab falls well outside of the downtown Austin area and is expanding well across the United States as things continue to move quickly with the company’s autonomous efforts in 2026. Today, various images of Cybercab fleets in interesting locations have started to circulate.
The most notable is a fleet of at least 20 Cybercabs at Miami International Airport in Florida. Spotted last night, the fleet is expansive and is indicative of a looming release of Cybercabs once regulatory boxes are checked off.
Tesla has already been operating the Robotaxi platform in Miami for several months, but this Cybercab fleet at the airport could be joining the ride-hailing platform as approvals arrive:

Another fleet of Cybercabs was spotted at the Devon, PA showroom just outside of Philadelphia. We have seen several Cybercab units testing around the Philadelphia Metro Area, which is interesting considering Tesla does not have any active Robotaxi geofence in Pennsylvania.

Philadelphia would be an ideal location to test ride-hailing due to its dense tourist population, large, sprawling city layout, and to compete with other ride-hailing companies that operate in the city.
Expansive fleets of Cybercabs will be popping up in and around major cities throughout the rest of the year, if we were betting on it. Tesla has made it obvious that the Cybercab rollout will be aggressive and fast-paced, but within reason. Tesla is still prioritizing safety, so these testing phases will likely go on for some period of time before more members of the public are able to snag a Cybercab for a personal chariot.
