TX fire chief slams inaccurate Tesla crash coverage with firsthand details on Model S fire
Immediately following the fatal Tesla crash in Texas this weekend, reports from both local and national media outlets emerged citing the statements of Harris County Pct. 4 Constable Mark Herman, who remarked that police were 100% certain that there was no one in the driver seat of the ill-fated Model S when it crashed. Herman also commented that the Tesla fire was so severe that it took over 30,000 gallons of water and four hours to extinguish the flames from the crash, and that firefighters had to reach out to the EV maker for help in battling the fire.
These statements have since been debunked (at least to some degree) by Tesla CEO Elon Musk, who noted that data logs that have been recovered so far from the ill-fated Model S indicate that Autopilot was not enabled during the crash, and that the vehicle did not have any Full Sell-Driving functions activated. Musk’s update essentially threw a wrench on the pervading narrative that Autopilot likely caused the tragic crash.
Your research as a private individual is better than professionals @WSJ!
Data logs recovered so far show Autopilot was not enabled & this car did not purchase FSD.
Moreover, standard Autopilot would require lane lines to turn on, which this street did not have.

And now, even the reports about the Tesla fire have been thrown into question–by the man whose team extinguished the blaze no less. In a statement to the Houston Chronicle, Palmer Buck, fire chief for The Woodlands Township Fire Department, noted that contrary to some reports in the media, the Tesla Model S fire did not burn out of control for four hours.
Interestingly enough, Buck remarked that his team actually managed to put down the fire within two to three minutes, which was enough for authorities to see that there were occupants in the vehicle. After these first two to three minutes, it was only a matter of keeping the batteries as cool as possible by pouring small amounts of water into the damaged battery pack. Buck described the fire department’s strategy in the following statement.
“With respect to the fire fight, unfortunately, those rumors grew way out of control. It did not take us four hours to put out the blaze. Our guys got there and put down the fire within two to three minutes, enough to see the vehicle had occupants. After that, it was simply cooling the car as the batteries continued to have a chain reaction due to damage.
“We could not tear it apart or move it around to get ‘final extinguishment’ because the fact that we had two bodies in there and it was then an investigation-slash-crime scene. We had to keep it cool, were on scene for four hours, but we were simply pouring a little bit of water on it. It was not because flames were coming out. It was a reaction in the battery pan. It was not an active fire,” Buck said.
As for the rumors that the fire department had to call a Tesla hotline for tips on how to handle a battery fire, the Fire Chief stated that these reports were untrue. “We did not (call Tesla), and I do not know where (that rumor) came from. There is a chance someone else did, maybe the Harris County Fire Marshal, but we did not call (Tesla). Tesla has an emergency manual for first responders,” Buck said. He also noted that he is not aware of Tesla having a hotline for tips on how to control a battery fire.
Buck also provided some new details about the Model S crash and how the fire department was involved. According to the fire chief, the first calls about the incident did not involve reports about a car at all. Instead, initial reports were about a fire in the woods. And while the Model S fire was notable when the firefighters arrived, it only took minutes to control the blaze from the vehicle.
“The first calls that came in were a fire in the woods. Then we got at 9:30 p.m. where we got the first call when someone said, ‘I see a car in a tree, and it is on fire. They reported a car hit a tree, and it had exploded… That is when we added extra units (to the response). There is a big lake, and (the accident) was just to the left of the lake, closer to the exiting part of the street, not the end of the cul de sac. It was at an undeveloped lot.
“(The Tesla) was heavily involved in flames. When the fire was put out, it was noticed there were two bodies (inside), and they were deceased. They continued extinguishment of the woods around (the car), putting out the trees and pine needles and what have you. I was there probably five to 10 minutes after that and at that point, every once in a while, the (battery) reaction would flame and it was mainly keeping water pouring on the battery,” Buck explained, adding that this was a process recommended by Tesla in cases of burning batteries.
While a number of the initial reports about the tragic Tesla crash this weekend have been debunked by Elon Musk and now, the fire chief for The Woodlands Township Fire Department, the incident continues to attract some degree of drama. As per recent reports, Harris County Pct. 4 Constable Mark Herman has stated that investigators would be serving a search warrant on Tesla to gain all data from the ill-fated Model S. Federal regulators from the NHTSA and NTSB have also launched an investigation into the crash.

Tesla has a Cybercab problem nobody saw coming
Tesla’s Cybercab line now builds robotaxis faster than Tesla can deploy them, Lars Moravy says.
Tesla’s Cybercab line in Texas can now build the two seat robotaxi faster than the company can put it into service, according to Lars Moravy, Tesla’s Vice President of Vehicle Engineering. “We don’t run every day because the line can run so fast. It’s currently outpacing our deployments,” Moravy said in a new Cybercab deep dive from Munro Live. “So, it’s a bit of a race right now. Who’s going to go faster? Right now the manufacturing line’s ahead.”
Tesla’s official Robotaxi account shared a Cybercab analysis video on X on Monday, calling it a “Cybercab engineering deep dive.” Moravy’s comments go further than what he told analysts on the Q3 earnings call last week, when he said the Cybercab line’s listed capacity of more than 125,000 units a year undersells what it can actually run.
The tour shows where that speed comes from. Tesla’s unboxed process splits the Cybercab into front, rear, side and center modules that are built and tested on their own before they meet on a short final line. That final line has just 25 fully automated stations, which Tesla’s team estimated is a fifth to a tenth of what a Model Y needs. The full line is about 78% automated, the framing line is already at 100%, and the layout uses roughly 50% less floor space per vehicle. The stated goal is “100% automation in 10 second cycle time,” or one finished Cybercab every 10 seconds.
Tesla also deleted the paint shop. Only the side modules are coated, and the exterior panels get their color inside the molding machine. Engineers said the car is designed to run at least 500,000 miles, which matters for a vehicle that will spend most of its day carrying riders.
The battery got the same treatment. The Cybercab uses an 88S6P pack of 4680 cells in a steel enclosure, a first for Tesla, with each module potted separately so a single failed module can be swapped instead of the whole pack. Wireless battery management boards replace a wiring harness, and new contactors are fast enough to drop the pyro fuse entirely. Tesla’s battery director graded the pack an A minus, compared with a D for the Model Y structural pack and a B minus for Cybertruck. Up front, the drive unit runs an 11:1 gear ratio versus roughly 9:1 on most Teslas, since the Cybercab does not need a high top speed.

The deployment side is now the bottleneck Moravy described. Tesla had more than 50 Cybercabs working the Formula 1 weekend in Austin, and Texas records show 463 Cybercabs registered. Tesla said on its earnings call that Cybercab service will launch in Dallas next month, and Moravy said the company is aiming to get Cybercabs to customers by the end of 2026. Every unit built so far has gone into Tesla’s own fleet since the line moved into volume production in April.
Munro Live also asked when it could get a Cybercab to tear down. Tesla’s answer: “Not yet.”
SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.
Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.
This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:
🚀 Elon says Raptor 4 will make 300 tons of thrust at sea level at roughly the same mass as Raptor 3.
How far Raptor has come:
Raptor 1: 185 tf, 2,080 kg
Raptor 2: 230 tf, 1,630 kg
Raptor 3: 250 tf, 1,525 kg
Raptor 4: 300 tf33 on Super Heavy = ~9,900 tf, nearly 3x Saturn V https://t.co/HQDswZhyvL

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.
This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.
Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.
Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.
The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.
Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.
For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.
Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.
Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.
Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.
The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.
🚨 Latvia has just received approval for Tesla Full Self-Driving (Supervised)
This is the 10th country in the EU to gain approval:
1. Netherlands — 10 April 2026 (original RDW approval)
2. Lithuania — 20 May 2026
3. Estonia — 29 May 2026
4. Denmark — 9 June 2026
5. Belgium — 10 June 2026
6. Slovenia — 7 September 2026
7. Czechia — 21 September 2026
8. Croatia — 29 September 2026
9. Slovakia — 16 October 2026— TESLARATI (@Teslarati) October 26, 2026
Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.
In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.
The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.
The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.
These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.
However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.
