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

California hits Tesla Cybercab and Robotaxi driverless cars with new law
California just gave police power to ticket driverless cars, including Tesla’s Cybercab fleet.
California DMV formally adopted new rules on April 29, 2026 that allow law enforcement to issue “notices of noncompliance”, or in other words, ticket autonomous vehicle companies when their cars commit moving violations. The rules take effect July 1, 2026, officially closes a regulatory gap that previously let driverless cars operate on public roads with nearly no traffic enforcement consequences.
Until now, state traffic law only applied to human “drivers,” which meant that when no person was behind the wheel, police had no mechanism to issue a ticket. Officers were limited to citing driverless vehicles for parking violations only. A well-known example came in September 2025, when a San Bruno officer watched a Waymo robotaxi execute an illegal U-turn and could do nothing but notify the company.
Under the new framework, when an officer observes a violation, the autonomous vehicle company is effectively treated as the driver. Companies must report each incident to the DMV within 72 hours, or 24 hours if a collision is involved. Repeated violations can result in fleet size restrictions, operational suspensions, or full permit revocation. Local officials also gained new authority to geofence driverless vehicles out of active emergency zones within two minutes and require a live emergency response line answered within 30 seconds.
Tesla Cybercab ramps Robotaxi public street testing as vehicle enters mass production queue
California’s new enforcement rules arrive at a pivotal moment for Tesla. The company is ramping Cybercab production at Giga Texas toward hundreds of units per week, targeting at least 2 million units annually at full capacity, while simultaneously pushing to expand its Robotaxi service to dozens of U.S. cities by end of 2026. Unsupervised FSD for consumer vehicles is currently targeted for Q4 2026, and when it arrives, Tesla’s fleet may not have a human to absorb legal accountability, under the July 1 rules.
Tesla has confirmed plans to expand its Robotaxi service to seven new cities in the first half of 2026, including Dallas, Houston, Phoenix, Miami, Orlando, Tampa, and Las Vegas, with the service already running without safety drivers in Austin. Musk has said he expects robotaxis to cover between a quarter and half of the United States by end of year.

Tesla Model X shocks everyone by crushing every other used car in America
The Model X is one of Tesla’s flagship models, the other being the Model S. Earlier this year, Tesla confirmed it would discontinue production of both the Model S and Model X to make way for Optimus robot production at the Fremont Factory in Northern California.
The Tesla Model X was the fastest-selling used vehicle in the United States in the first quarter of the year, crushing every other used car in America.
iSeeCars data for the first quarter shows that the Model X was the fastest-selling used car, lasting just 25.6 days on the market on average, two days better than that of the second-place Lexus RX 350h. The Cybertruck, Model Y, and Model S, in seventh, ninth, and thirteenth place, respectively, also made the list.
The Model X is one of Tesla’s flagship models, the other being the Model S. Earlier this year, Tesla confirmed it would discontinue production of both the Model S and Model X to make way for Optimus robot production at the Fremont Factory in Northern California.
Tesla brings closure to flagship ‘sentimental’ models, Musk confirms
Bringing closure to these two vehicles signaled the end of the road for the cars that have effectively built Tesla’s reputation for luxury and high-end passenger vehicles.
Relying on the sales of its mass market Model Y and Model 3, as well as leaning on the success of future products like the Cybercab, is the angle Tesla has chosen to take.
Teslas are also performing extremely well as a whole on the resale market. iSeeCars data shows that, “while the average price of a 1- to 5-year-old non-Tesla EV fell 10.3% in Q1 2026 year-over-year, the average price of a used Tesla was essentially flat at 0.1% lower across the same period. Traditional gas car prices dropped 2.8% during this same period.”
Additionally, market share for gas cars has dropped nearly 3 percent since the same quarter last year. Tesla has remained level, while the non-Tesla EV market share has increased 30 percent, mostly due to more models available.
Nevertheless, those non-Tesla EVs have seen their value drop by over 10 percent, while Tesla’s values have remained level.
Executive Analyst Karl Brauer said:
“Used electric vehicles without a Tesla badge have lost more than 10% of their value in the past year. This compares to stable values for Teslas and hybrids, and a modest 2.8% drop for traditional gasoline vehicles.”
Teslas, as well as non-luxury hybrids, are displaying the strongest resistance in the face of faltering demand, the publication says. But the more impressive performance is that of the Model X alone.
Tesla’s decision to stop production of the Model X may have played some part in the vehicle’s pristine performance in Q1. With the car already placed at a premium price point, used models are already more appealing to consumers. Perhaps second-hand versions were more than enough for those who wanted a Model X, and only a Model X.

Tesla Cybertruck’s head-scratching trim sold terribly, recall documents reveal
The head-scratching offering was only available for a few months, and evidently, it did not sell very well, which we all suspected. New recall documents on the vehicle from the National Highway Traffic Safety Administration (NHTSA) now reveal just how poorly it sold.
After Tesla decided to build a Rear-Wheel-Drive Cybertruck trim back in 2025, which was void of many features and only featured a small discount.
The head-scratching offering was only available for a few months, and evidently, it did not sell very well, which we all suspected. New recall documents on the vehicle from the National Highway Traffic Safety Administration (NHTSA) now reveal just how poorly it sold.
The recall deals with a potentially separating wheel stud and potentially impacts 173 Cybertruck units with the 18-inch steel wheels. The Cybertruck RWD was the only trim level to feature these, and the 173 potentially impacted units represent a portion of the population of pickups. Therefore, it’s not the entire number of RWD Cybertruck sold, but it could show how little interest it gathered.
The NHTSA document states:
“On affected vehicles, higher severity road perturbations and cornering may strain the stud hole in the wheel rotor, causing cracks to form. If cracking propagates with continued use and strain, the wheel stud could eventually separate from the wheel hub.”
Only 5 percent are expected to be impacted, meaning less than 10 units will have the issue if the NHTSA and Tesla estimates are correct. Nevertheless, the true story here is how terribly the RWD Cybertruck sold.
Tesla ended production and stopped offering the RWD Cybertruck to customers last September. For just $10,000 less than the All-Wheel-Drive trim, Tesla offered the RWD Cybertruck with just one motor, textile seats instead of leather, only 7 speakers instead of 15, no Rear Touchscreen, no Powered Tonneau Cover for the truck bed, and no 120v/240v outlets.
For just $10,000 more, at $79,990, owners could have received all of those premium features, as well as a more capable All-Wheel-Drive powertrain that featured Adaptive Air Suspension. The discount simply was not worth the sacrifices.
Orders were few and far between, and sources told us that when it was offered, sales were extremely tempered because customers could not see the value in this trim level.
Even Tesla’s most loyal supporters thought the offering was kind of a joke, and the $10,000 extra was simply worth it.
