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 CEO Elon Musk said that flying cars will be coming to the market, something that his own company has hinted at previously.
Musk said on X, in response to a post that read, “We were promised flying cars and all we got is infinite superintelligence for everyone,” “You will get flying cars.”
You will get flying cars
— Elon Musk (@elonmusk) August 12, 2026
The post rang back to when Musk teased flying and hovering capabilities for the Tesla Roadster, the company’s supercar that has been delayed more times than anyone cares to count. It was set for an unveiling earlier this year, but it was then pushed back to August. There is still no sign of it coming.
However, that does not mean it won’t. But one of the biggest features of the Roadster that was teased was a SpaceX package that featured cold gas thrusters on the rear end that would help with white-knuckle acceleration. Another set would face the ground and would help the Roadster gain small bits of altitude, potentially helpful to jump over obstacles.

But it is not a straightforward thing for Musk. As a serial entrepreneur, he tends to spend his time on major disruptors; currently, his largest projects are artificial intelligence and compute power, as well as SpaceX’s launches that will eventually make life multiplanetary.
In the past, he has been critical of flying cars and has been in favor of tunnels, one of the big reasons he started the Boring Company. In 2017 at a TED talk, he said:
“There is a challenge with flying cars in that they’ll be quite noisy. The wind force generated will be very high. Let’s just say that if something’s flying over your head, if there are a whole bunch of flying cars all over the place, that is not an anxiety-reducing situation…You’re thinking, ‘Did they service their hubcap? Or is it going to come off and guillotine me as they’re flying past?’”
However, he’s never been against them. He has also said he’s in favor of both tunnels and flying cars.
Contrary to press reports, I’m not against flying cars. Just said it was important to consider both pros and cons.
— Elon Musk (@elonmusk) March 24, 2015
Most recently, Musk said that anyone who wants a flying car should be able to get one. This was stated last October on the Joe Rogan Experience:
-
“My friend Peter Thiel once reflected that the future was supposed to have flying cars, but we don’t have flying cars… I think if Peter wants a flying car, we should be able to buy one.”
Whether the Roadster will be Tesla’s flying car or potentially another one remains in the mind of Musk. Of course, the Roadster will have to make its way to production lines before we find out.

SpaceX’s next trillion dollar bet has nothing to do with rockets, Musk tells staff
Elon Musk told SpaceX staff AI revenue will soon dwarf rockets and Starlink combined entirely.
Elon Musk told SpaceX employees this week that artificial intelligence, not rockets, will soon carry the company’s revenue. In a roughly 29 minute internal address posted on SpaceX’s X account on Tuesday, Musk said AI revenue will pass every other line of business at SpaceX “probably in September” and pull further ahead by the fourth quarter.
The numbers he gave are specific. SpaceX currently runs 1.4 gigawatts of AI compute capacity. Musk wants that at 10 gigawatts by the end of 2027, a jump he tied directly to revenue: “if we bring 10GW of AI online by the end of next year, it will be $300 billion to $500 billion a year in revenue.” He called those “big numbers,” which undersells a projection larger than what most countries produce in a year.
We made rockets reusable and are rebuilding the internet in space. The next challenge: making life multiplanetary and understanding the true nature of the universe

Musk went further on where AI fits into SpaceX’s future. “Probably in four or five years, AI will be 99% of the value of SpaceX,” he told staff, adding that digital intelligence would eventually run “a trillion times” ahead of biological intelligence as computing scales. He tied that growth to the company’s founding mission, telling employees “we must win on AI, because the future is overwhelmingly AI and robots,” with the payoff meant to help fund Starship and a Mars program that increasingly runs through Terafab, the joint Tesla, SpaceX and xAI chip plant.

None of this is entirely new territory. SpaceX told investors much the same story during its first earnings call as a public company on August 4, where Musk moved the company’s $1 trillion revenue target up a year to 2030 and said Starlink could someday carry a majority of the world’s internet. What the all hands video adds is a hard deadline and a specific power figure Musk had not given publicly before, along with a franker pitch to his own workforce that AI, not launch cadence, is now the thing SpaceX is betting its future on.
The AI revenue itself is not coming from SpaceX training its own models. It is largely Starlink acting as the network layer for xAI’s workloads, plus SpaceX renting out compute capacity directly, the same approach behind the roughly $16 billion the company spent on AI infrastructure in a single quarter.
Musk closed the video with a pitch aimed at recruiting and retention rather than investors, telling employees that anyone who helps SpaceX win the AI race will eventually get the chance to go to the moon or Mars themselves. Whether SpaceX can turn 1.4 gigawatts into 10 in seventeen months is the more immediate question, and one that will show up in quarterly numbers well before anyone leaves Earth.
In a new note to investors on Tuesday, Morgan Stanley analyst Andrew Percoco said that Tesla has one big financial question to answer for investors regarding its Robotaxi rollout, Full Self-Driving software, and Optimus.
Percoco said in the note that, for the most part, investors are still very positive about the direction the company is headed. However, there are some things the firm would like to see, and they have to do with financials.
Tesla (TSLA) Q2 2026 earnings results: miss on EPS, beat on revenue
Tesla bulls are more than convinced that the company’s Full Self-Driving software is proof it can develop physical AI. Financially, however, there are still some questions, especially on elevated spending, which CEO Elon Musk said would occur as the company works to roll out Robotaxi faster and continue developing its Optimus robot.
The latter two are where Tesla will have to prove progress to investors, as Percoco writes that both projects “will require clearer evidence that Robotaxi is scaling and more tangible Optimus proof points to support the ROI on elevated capex.”
Percoco said the second quarter earnings call did not change his long-term thesis of where Tesla is positioned in the AI race, which is out in front. However, there are concerns that weaker gross margins and higher R&D spend will stress financials, and that has “sharpened our (and investors’) focus on measurable progress across Robotaxi and Optimus.”
Additionally, Robotaxi still needs to be proven with more operation in existing cities while maintaining safety but improving how many rides it gives in any given time, he said. For Optimus, Percoco wrote that he is “still looking for evidence beyond commentary around SOP.”

Morgan Stanley put Percoco in charge of covering Tesla after long-time analyst Adam Jonas transitioned to the automotive side.
Currently, Morgan Stanley has a $415 price target on Tesla and a ‘Hold’ rating on the stock. It is trading at around $330 at the time of publication, which was 2:30 P.M. on the East Coast.
