This weekend, a tragic crash involving a 2019 Tesla Model S ended up claiming the lives of two individuals, a 59-year-old and a 69-year-old, both of whom are yet to be identified. Considering the nature of the case and partly due to the involvement of a Tesla, the incident has been covered by both local and national media outlets. This became quite notable in social media platforms, where the crash has been linked to Autopilot.

This guide presents what is currently known about the tragic incident, as well as some commentary and videos from EV owners who have attempted to replicate (at least to a degree) the alleged events that led up to the tragic Model S crash.
What happened?
On Saturday night, a 2019 Model S crashed into a tree at about 11:25 p.m. in the Carlton Woods Subdivision on Hammock Dunes Place in Houston, Texas. According to authorities, the Model S crashed into a tree after failing to navigate a turn at high speed near 18 Hammock Dunes Place. The collision resulted in a fire that took the local fire department about four hours and over 30,000 gallons of water to extinguish. Investigators have found two victims from the incident, one sitting on the passenger seat and another in the back seat.
What did witnesses say?
KPRC 2 reporter Deven Clarke was able to speak to one of the victims’ brother-in-law, who stated that the Tesla owner and a friend simply wanted to take the car out for a spin. The brother-in-law remarked that there were just two people in the vehicle. He also added that the Tesla owner backed out of the driveway and then may have hopped in the back seat before crashing a few hundred yards down the road. The owner was reportedly the person found in the back seat of the car.
What has the police said?
In a statement to KHOU-11, Harris County Pct. 4 Constable Mark Herman remarked that deputies who recovered the Tesla are certain that the vehicle had no driver when it collided with the tree. He also emphasized that some of the authorities who responded to the incident were reconstructionists, and that they were very confident that there was no one driving the vehicle when it crashed.
“They are 100% certain that no one was in the driver seat driving that vehicle at the time of impact. They are positive. And again, the height from the back seat to the front seat, that would be almost impossible, but again our investigators are trained. They handle collisions. Several of our folks are reconstructionists, but they feel very confident just with the positioning of the bodies after the impact that there was no one driving that vehicle,” Herman said.
Was Autopilot involved?
Despite the inflammatory social media posts from some media outlets, it has not been determined yet if Autopilot had been active in the Model S when it collided with the tree. It should be noted that the roads in the Carlton Woods Subdivision on Hammock Dunes Place do not seem to have visible lane lines, which is a requirement for Autopilot’s activation. Regular cruise control could be activated in such areas as per videos from Tesla owners, but Autopilot and Full Self-Driving features are generally inaccessible in a residential area, at least in their current state.
This should dismiss the idea that AP was somehow the cause of this horrific incident. I pray for the family and friends of the deceased. Let’s trust the real investigators will discover what really happened here. pic.twitter.com/0tp8Vbh6fH

Is the NTSB investigating the incident?
In a statement to Bloomberg, National Transportation Safety Board spokesperson Chris O’Neil confirmed that the NTSB does not plan to open a new probe about the tragic incident.
What happens when Autopilot is engaged and a driver unbuckles the seatbelt?
One scenario that has been suggested is that the driver might have activated Autopilot and jumped into the back seat. This would have been a tricky maneuver as the driver would have had to unbuckle himself, which results in Teslas engaging their alerts and eventually coming to a stop. Such a scenario was demonstrated by FSD Beta user @brandonee916.

Tesla confirms that work on Dojo 3 has officially resumed
“Now that the AI5 chip design is in good shape, Tesla will restart work on Dojo 3,” Elon Musk wrote in a post on X.
Tesla has restarted work on its Dojo 3 initiative, its in-house AI training supercomputer, now that its AI5 chip design has reached a stable stage.
Tesla CEO Elon Musk confirmed the update in a recent post on X.
Tesla’s Dojo 3 initiative restarted
In a post on X, Musk said that with the AI5 chip design now “in good shape,” Tesla will resume work on Dojo 3. He added that Tesla is hiring engineers interested in working on what he expects will become the highest-volume AI chips in the world.
“Now that the AI5 chip design is in good shape, Tesla will restart work on Dojo3. If you’re interested in working on what will be the highest volume chips in the world, send a note to AI_Chips@Tesla.com with 3 bullet points on the toughest technical problems you’ve solved,” Musk wrote in his post on X.
Musk’s comment followed a series of recent posts outlining Tesla’s broader AI chip roadmap. In another update, he stated that Tesla’s AI4 chip alone would achieve self-driving safety levels well above human drivers, AI5 would make vehicles “almost perfect” while significantly enhancing Optimus, and AI6 would be focused on Optimus and data center applications.
Musk then highlighted that AI7/Dojo 3 will be designed to support space-based AI compute.
Tesla’s AI roadmap
Musk’s latest comments helped resolve some confusion that emerged last year about Project Dojo’s future. At the time, Musk stated on X that Tesla was stepping back from Dojo because it did not make sense to split resources across multiple AI chip architectures.
He suggested that clustering large numbers of Tesla AI5 and AI6 chips for training could effectively serve the same purpose as a dedicated Dojo successor. “In a supercomputer cluster, it would make sense to put many AI5/AI6 chips on a board, whether for inference or training, simply to reduce network cabling complexity & cost by a few orders of magnitude,” Musk wrote at the time.
Musk later reinforced that idea by responding positively to an X post stating that Tesla’s AI6 chip would effectively be the new Dojo. Considering his recent updates on X, however, it appears that Tesla will be using AI7, not AI6, as its dedicated Dojo successor. The CEO did state that Tesla’s AI7, AI8, and AI9 chips will be developed in short, nine-month cycles, so Dojo’s deployment might actually be sooner than expected.

Elon Musk’s xAI brings 1GW Colossus 2 AI training cluster online
Elon Musk shared his update in a recent post on social media platform X.
xAI has brought its Colossus 2 supercomputer online, making it the first gigawatt-scale AI training cluster in the world, and it’s about to get even bigger in a few months.
Elon Musk shared his update in a recent post on social media platform X.
Colossus 2 goes live
The Colossus 2 supercomputer, together with its predecessor, Colossus 1, are used by xAI to primarily train and refine the company’s Grok large language model. In a post on X, Musk stated that Colossus 2 is already operational, making it the first gigawatt training cluster in the world.
But what’s even more remarkable is that it would be upgraded to 1.5 GW of power in April. Even in its current iteration, however, the Colossus 2 supercomputer already exceeds the peak demand of San Francisco.
Commentary from users of the social media platform highlighted the speed of execution behind the project. Colossus 1 went from site preparation to full operation in 122 days, while Colossus 2 went live by crossing the 1-GW barrier and is targeting a total capacity of roughly 2 GW. This far exceeds the speed of xAI’s primary rivals.
Funding fuels rapid expansion
xAI’s Colossus 2 launch follows xAI’s recently closed, upsized $20 billion Series E funding round, which exceeded its initial $15 billion target. The company said the capital will be used to accelerate infrastructure scaling and AI product development.
The round attracted a broad group of investors, including Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, Qatar Investment Authority, MGX, and Baron Capital Group. Strategic partners NVIDIA and Cisco also continued their support, helping xAI build what it describes as the world’s largest GPU clusters.
xAI said the funding will accelerate its infrastructure buildout, enable rapid deployment of AI products to billions of users, and support research tied to its mission of understanding the universe. The company noted that its Colossus 1 and 2 systems now represent more than one million H100 GPU equivalents, alongside recent releases including the Grok 4 series, Grok Voice, and Grok Imagine. Training is also already underway for its next flagship model, Grok 5.

Musk details AI chip roadmap
In his post, Elon Musk stated that Tesla’s AI5 chip design is “almost done,” while AI6 has already entered early development. Musk added that Tesla plans to continue iterating rapidly, with AI7, AI8, AI9, and future generations targeting a nine-month design cycle.
He also noted that Tesla’s in-house chips could become the highest-volume AI processors in the world. Musk framed his update as a recruiting message, encouraging engineers to join Tesla’s AI and chip development teams.
Tesla community member Herbert Ong highlighted the strategic importance of the timeline, noting that faster chip cycles enable quicker learning, faster iteration, and a compounding advantage in AI and autonomy that becomes increasingly difficult for competitors to close.
AI5 manufacturing takes shape
Musk’s comments align with earlier reporting on AI5’s production plans. In December, it was reported that Samsung is preparing to manufacture Tesla’s AI5 chip, accelerating hiring for experienced engineers to support U.S. production and address complex foundry challenges.
Samsung is one of two suppliers selected for AI5, alongside TSMC. The companies are expected to produce different versions of the AI5 chip, with TSMC reportedly using a 3nm process and Samsung using a 2nm process.
Musk has previously stated that while different foundries translate chip designs into physical silicon in different ways, the goal is for both versions of the Tesla AI5 chip to operate identically. AI5 will succeed Tesla’s current AI4 hardware, formerly known as Hardware 4, and is expected to support the company’s Full Self-Driving system as well as other AI-driven efforts, including Optimus.
