Driver of Model X crash in Montana pens open letter to Musk, calls Tesla drivers “lab rats” [Updated]
Pang, the driver of the Model X that crashed in Montana earlier this month has posted an open letter to Elon Musk and Tesla asking the company to “take responsibility for the mistakes of Tesla products”. He accuses Tesla for allegedly using drivers as “lab rats” for testing of its Autopilot system.
In an email sent to us and also uploaded to the Tesla Motors Club forum, Pang provides a detailed account of what happened the day of the crash. He says he and a friend drove about 600 miles on Interstate 90 on the way to Yellowstone National Park. When he exited the highway to get on Montana route 2, he drove for about a mile, saw conditions were clear, and turned on Autopilot again. Pang describes what happened next as follows:
“After we drove about another mile on state route 2, the car suddenly veered right and crashed into the safety barrier post. It happened so fast, and we did not hear any warning beep. Autopilot did not slow down at all after the crash, but kept going in the original speed setting and continued to crash into more barrier posts in high speed. I managed to step on the break, turn the car left and stopped the car after it crashed 12 barrier posts.
“After we stopped, we heard the car making abnormal loud sound. Afraid that the battery was broken or short circuited, we got out and ran away as fast as we could. After we ran about 50 feet, we found the sound was the engine were still running in high speed. I returned to the car and put it in parking, that is when the loud sound disappeared.”
Pang goes on to explain how his Tesla Model X driving on Autopilot continued to travel on its own even after veering off the road and crashing into a roadside stake. “I was horrified by the fact that the Tesla autopilot did not slow down the car at all after the intial crash. After we crashed on the first barrier post, autopilot continued to drive the car with the speed of 55 to 60 mph, and crashed another 11 posts. Even after I stopped the car, it was still trying to accelerate and spinning the engine in high speed. What if it is not barrier posts on the right side, but a crowd?”

After the accident, Tesla reviewed the driving logs from the Model X and reported that the car was operating for more than two miles with no hands on the steering wheel, despite numerous alarms and warnings issued by the car. Pang says he never heard any audible warnings. Comments on TMC range from the incredulous to the acerbic. Most feel Teslas simply don’t operate the way Pang said his car did. Among other discrepancies, the cars are designed to put themselves in Park if the driver’s door is opened with no one in the driver’s seat.
But that hasn’t stopped Pang from voicing his strong opinions on Tesla’s Autopilot system. “It is clear that Tesla is selling a beta product with bugs to consumers, and ask the consumers to be responsible for the liability of the bugging autopilot system. Tesla is using all Tesla drivers as lab rats.”
A car that crashes but continues to accelerate is certainly a scary thought. There is no way to resolve the discrepancy between what Pang says happened and Tesla’s account of what occurred. In an updated email sent to us by friend and english translator for Mandarin speaking Pang, Tesla has reached out to Pang to address the matter.
The original open letter from Pang reads as follows:
A Public Letter to Mr. Musk and Tesla For The Sake Of All Tesla Driver’s Safety
From the survivor of the Montana Tesla autopilot crash
My name is Pang. On July 8, 2016, I drove my Tesla Model X from Seattle heading to Yellowstone Nation Park, with a friend, Mr. Huang, in the passenger seat. When we were on highway I90, I turned on autopilot, and drove for about 600 miles. I switched autopilot off while we exited I90 in Montana to state route 2. After about 1 mile, we saw that road condition was good, and turned on autopilot again. The speed setting was between 55 and 60 mph. After we drove about another mile on state route 2, the car suddenly veered right and crashed into the safety barrier post. It happened so fast, and we did not hear any warning beep. Autopilot did not slow down at all after the crash, but kept going in the original speed setting and continued to crash into more barrier posts in high speed. I managed to step on the break, turn the car left and stopped the car after it crashed 12 barrier posts. After we stopped, we heard the car making abnormal loud sound. Afraid that the battery was broken or short circuited, we got out and ran away as fast as we could. After we ran about 50 feet, we found the sound was the engine were still running in high speed. I returned to the car and put it in parking, that is when the loud sound disappeared. Our cellphone did not have coverage, and asked a lady passing by to call 911 on her cellphone. After the police arrived, we found the right side of the car was totally damaged. The right front wheel, suspension, and head light flied off far, and the right rear wheel was crashed out of shape. We noticed that the barrier posts is about 2 feet from the white line. The other side of the barrier is a 50 feet drop, with a railroad at the bottom, and a river next. If the car rolled down the steep slope, it would be really bad.
Concerning this crash accident, we want to make several things clear:
1. We know that while Tesla autopilot is on but the driver’s hand is not on the steering wheel, the system will issue warning beep sound after a while. If the driver’s hands continue to be off the steering wheel, autopilot will slow down, until the driver takes over both the steering wheel and gas pedal. But we did not hear any warning beep before the crash, and the car did not slow down either. It just veered right in a sudden and crashed into the barrier posts. Apparently the autopilot system malfunctioned and caused the crash. The car was running between 55 and 60 mph, and the barrier posts are just 3 or 4 feet away. It happened in less than 1/10 of a second from the drift to crash. A normal driver is impossible to avoid that in such a short time.
2. I was horrified by the fact that the Tesla autopilot did not slow down the car at all after the intial crash. After we crashed on the first barrier post, autopilot continued to drive the car with the speed of 55 to 60 mph, and crashed another 11 posts. Even after I stopped the car, it was still trying to accelerate and spinning the engine in high speed. What if it is not barrier posts on the right side, but a crowd?
3. Tesla never contacted me after the accident. Tesla just issued conclusion without thorough investigation, but blaming me for the crash. Tesla were trying to cover up the lack of dependability of the autopilot system, but blaming everything on my hands not on the steering wheel. Tesla were not interested in why the car veered right suddenly, nor why the car did not slow down during the crash. It is clear that Tesla is selling a beta product with bugs to consumers, and ask the consumers to be responsible for the liability of the bugging autopilot system. Tesla is using all Tesla drivers as lab rats. We are willing to talk to Tesla concerning the accident anytime, anywhere, in front of the public.
4. CNN’s article later about the accident was quoting out of context of our interview. I did not say that I do not know either Tesla or me should be responsible for the accident. I might consider buying another Tesla only if they can iron out the instability problems of their system.
As a survivor of such a bad accident, a past fan of the Tesla technology, I now realized that life is the most precious fortune in this world. Any advance in technology should be based on the prerequisite of protecting life to the maximum extend. In front of life and death, any technology has no right to ignore life, any pursue and dream on technology should first show the respect to life. For the sake of the safety of all Tesla drivers and passengers, and all other people sharing the road, Mr. Musk should stand up as a man, face up the challenge to thoroughly investigate the cause of the accident, and take responsibility for the mistakes of Tesla product. We are willing to publicly talk to you face to face anytime to give you all the details of what happened. Mr. Musk, you should immediately stop trying to cover up the problems of the Tesla autopilot system and blame the consumers.
Tesla’s Response on TMC
TM Ownership, Saturday at 12:11 PM
Dear Mr. Pang,
We were sorry to hear about your accident, but we were very pleased to learn both you and your friend were ok when we spoke through your translator on the morning of the crash (July 9). On Monday immediately following the crash (July 11), we found a member of the Tesla team fluent in Mandarin and called to follow up. When we were able to make contact with your wife the following day, we expressed our concern and gathered more information regarding the incident. We have since made multiple attempts (one Wednesday, one Thursday, and one Friday) to reach you to discuss the incident, review detailed logs, and address any further concerns and have not received a call back.
As is our standard procedure with all incidents experienced in our vehicles, we have conducted a thorough investigation of the diagnostic log data transmitted by the vehicle. Given your stated preference to air your concerns in a public forum, we are happy to provide a brief analysis here and welcome a return call from you. From this data, we learned that after you engaged Autosteer, your hands were not detected on the steering wheel for over two minutes. This is contrary to the terms of use when first enabling the feature and the visual alert presented you every time Autosteer is activated. As road conditions became increasingly uncertain, the vehicle again alerted you to put your hands on the wheel. No steering torque was then detected until Autosteer was disabled with an abrupt steering action. Immediately following detection of the first impact, adaptive cruise control was also disabled, the vehicle began to slow, and you applied the brake pedal.
Following the crash, and once the vehicle had come to rest, the passenger door was opened but the driver door remained closed and the key remained in the vehicle. Since the vehicle had been left in Drive with Creep Mode enabled, the motor continued to rotate. The diagnostic data shows that the driver door was later opened from the outside and the vehicle was shifted to park. We understand that at night following a collision the rotating motors may have been disconcerting, even though they were only powered by minimal levels of creep torque. We always seek to learn from customer concerns, and we are looking into this behavior to see if it can be improved. We are also continually studying means of better encouraging drivers to adhere to the terms of use for our driver assistance features.
We are still seeking to speak with you. Please contact Tesla service so that we can answer any further questions you may have.
Sincerely,
The Tesla team
Tesla has expanded the footprint of a massive safety feature worldwide with a recent Software Update labeled as 2026.20.6. The expansion of the “Blind Spot Warning While Parked” feature represents the more widespread availability of the feature, which aims to prevent “dooring.”
Dooring is when a driver or passenger opens a car door into the path of an oncoming road user, usually a cyclist or motorcyclist. It is among the most common types of cycling accidents, the League of American Bicyclists says.
For this reason, Tesla created a feature that warns occupants not to open the door because an object is approaching. The feature will sound a chime, and it will also delay the opening of the door to prevent an incident.
The release notes state (via Not a Tesla App):
“If you attempt to open a door while an approaching object is detected in your blind spot (for example, a bicyclist approaching from behind) a chime sounds, and your door will not open upon initial button press. Wait a short time and press the button a second time to override the warning.”
Tesla initially rolled out this feature back in 2024 with the Model 3 “Highland.” However, it remained with the Model 3 exclusively for over a year; that was until Tesla added it to the Cybertruck this past Spring.
Now, it is making its way to the new Model Y, 2021 and newer Model S, and 2021 or newer Model X.
The prevention of dooring incidents could eliminate many injuries to cyclists, especially in an urban setting. Dooring accounts for 10-20 percent of bike-related crashes in major cities, and over 17,000 dooring-related incidents were treated in the U.S. over the course of a decade. These usually involve fractures, contusions, and head trauma.
Tesla confirmed this morning that it has sent the first production units, manufactured with no steering wheel or pedals, to on-road testing in Austin, sharing video of the first rides with no human controls.
The lack of steering wheels and pedals in the Cybercab aligns with Tesla’s self-certification of Robotaxi as Level 4 SAE, a platform it plans to make widespread through internal vehicles and customer-owned cars that will operate and generate revenue for individuals.
The start of these engineering tests is a major signal for Tesla, which plans to bring driverless, wheel-less, and pedal-less Cybercabs to market in the coming months. With production already well underway at Gigafactory Texas, where the Cybercab is built, there is some inclination to believe the first public rides could happen sooner rather than later.

Tesla’s engineering tests will put the Cybercab in real-world scenarios, testing not only the hardware, but more importantly, the software that drives the car around Austin with nobody supervising it within the car.
This is perhaps the biggest part of the internal testing process, especially prior to allowing regular, everyday people to hail the Cybercab for an autonomous ride. These early rides serve as a true benchmark for Tesla: How many rides can it achieve safely? How many miles did it travel consecutively without needing an intervention? What scenarios challenge the Full Self-Driving suite the most?
The proper precautions have already been put into place as well, as Tesla released the First Responders Guide to Cybercab over the weekend, ensuring that emergency services have 24/7 access to Robotaxi Assistance, as well as other boundaries, such as Geofencing features that can be used to redirect autonomous vehicle traffic due to accidents, road closures, construction, or maintenance.
Cybercab seems genuinely close to being added to the Robotaxi fleet in Austin, but Tesla has prioritized safety throughout this entire process. Therefore, we think it could be months before it truly starts giving rides to the public. People have been frustrated with this, but Robotaxi in Austin has a tremendous safety record so far, so the slow rollout has kept people safe and accidents to a minimum.
The most important thing is that Tesla continues to show consistent progress in the Cybercab’s ramp-up toward fleet addition. A few weeks back, we saw the EPA reward the Cybercab a Certificate of Conformity, allowing it to enter the stream of commerce. Then, we saw Tesla add decals, signaling that it was likely about to start testing it publicly. That has now happened.
The next big move will be the announcement of the first rides, so this Summer should be filled with anticipation.
For years, there have been images and videos across social media platforms that have reminded me of when I was a 15-year-old kid teased by “Xbox 720” videos on YouTube. These videos are of the supposed “Tesla Phone” that Elon Musk was secretly developing in between leading Tesla with its electric cars and SpaceX with its reusable rockets.

Although Musk has put those rumors to bed several times, it was never completely out of the realm that he could get involved in cell phones in some capacity. Think outside the box and more macro-level, though. Instead of reinventing the computer, Musk reinvented connectivity by developing Starlink with SpaceX.
It could be something similar, TD Cowen analyst Gregory Williams said in a note last week, where he hinted SpaceX could be gathering some steam to acquire T-Mobile.
Williams said it would be the “clear choice” for SpaceX if it decided to go through with a network acquisition. He also suggested AT&T.
The move would be possible through selling more of its own stock, which would help SpaceX raise the money to purchase T-Mobile, which would cost roughly $300 billion. It could be one of the moves SpaceX makes post-IPO in terms of an acquisition: it already acquired Cursor AI for $60 billion.
Other analysts, like Dan Ives of Wedbush, believe SpaceX and Tesla will eventually merge into one anyway, and that conglomeration could come as soon as this year, some have said.
The implications of SpaceX purchasing T-Mobile are massive. A combined entity would create a truly ubiquitous network: T-Mobile’s terrestrial 5G towers and Starlink’s growing constellation of Direct-to-Cell satellites. This would essentially eliminate dead zones across the U.S. and potentially globally.
SpaceX would instantly become a full-scale facilities-based carrier with satellite differentiation; a huge advantage. This would pressure AT&T and Verizon heavily.
There are also concerns like a potential reduction in long-term competition, and of course, a deal of that size would face intense scrutiny from government agencies.
The strategic fit is compelling due to the existing Starlink–T-Mobile partnership and complementary technologies (space + terrestrial). It could create a dominant integrated communications player. However, the regulatory, financial, and execution hurdles are enormous — this remains highly speculative with no indication SpaceX is actively pursuing it right now.
