Tesla’s Elon Musk, NTSB chief hold ‘constructive’ talk amid Model X crash probe

Published

on

Tesla CEO Elon Musk and NTSB chief Robert Sumwalt spoke this past weekend about the agency’s ongoing probe into last month’s fatal Model X accident. 

In a statement to Reuters, NTSB spokesman Peter Knudson noted that the Tesla CEO and the agency’s chief discussed several points during their conversation. Among these are the NTSB’s investigative process and Tesla’s initiatives to address safety recommendations that were issued last year.

“NTSB Chairman Robert Sumwalt had what he described as a very constructive conversation with Mr. Musk over the weekend. They discussed the investigation of the March 23 Tesla crash, NTSB investigative processes, and Tesla’s work to address the safety recommendations that were issued last year.” Knudson said.

Tesla and the NTSB were recently engaged in a spat over the electric car maker’s decision to release information pertinent to the agency’s probe. A few days after the investigations began, pictures of NTSB investigators retrieving modules from the ill-fated Model X emerged. The agency later confirmed that it was able to recover the Model X’s restraint control module and its infotainment module. Tesla also released an update outlining what it knows so far about the Model X crash. 

Tesla released an update on March 30, stating that Autopilot was engaged when the electric SUV collided with the highway barrier. According to Tesla, Autopilot was activated with adaptive cruise control set to minimum. The driver also had roughly 5 seconds and 150 meters of unobstructed view before the Model X collided the barrier, but no action was taken.

On April 1, the NTSB issued a statement saying that it was “unhappy” with Tesla’s release of investigative information. In a comment to the Washington Post, NTSB spokesman Chris O’Neil expressed the agency’s reservations about Tesla’s preliminary explanation.

“At this time the NTSB needs the assistance of Tesla to decode the data the vehicle recorded. In each of our investigations involving a Tesla vehicle, Tesla has been extremely cooperative on assisting with the vehicle data. However, the NTSB is unhappy with the release of investigative information by Tesla.

“We will work to determine the probable cause of the crash, and our next update of information about our investigation will likely be when we publish a preliminary report, which generally occurs within a few weeks of completion of field work,” O’Neil said.

Responding to the NTSB’s statement, Elon Musk tweeted that Tesla’s policy has always been to release critical crash data, in particular, information that affects public safety. According to Musk, doing otherwise would be “unsafe.”

“Lot of respect for NTSB, but NHTSA regulates cars, not NTSB, which is an advisory body. Tesla releases critical crash data affecting public safety immediately & always will. To do otherwise would be unsafe,” Musk said.

Elon Musk has reaffirmed the Tesla Semi’s mass production date. He mentioned the update in a post on social media platform X during the weekend.

Tesla Semi Factory

The Tesla Semi was initially unveiled in late 2017, and its first deliveries were held in December 2022. Since then, Tesla has only been delivering the Semi to a handful of customers while it builds a dedicated factory for the Class 8 all-electric truck near its Giga Nevada facility.

Drone flyovers of the Tesla Semi factory over the past months have suggested that progress in the construction of the facility has been steady. More recent flyovers have even suggested that Tesla is now busy outfitting the facility with the necessary equipment for the mass production of the Semi.

Elon Musk’s Recent Comments

In a recent comment on X, Elon Musk reiterated the idea that the Semi was indeed expected to be mass produced in 2026. Musk shared his update as a response to a Tesla bull who recalled that Bill Gates did not believe that the Semi was feasible due to the limitations of battery technology. In his response, Musk posted a laughing emoji together with “Tesla Semi will be in volume production next year.” 

The Tesla Semi factory near Giga Nevada is expected to be capable of producing 50,000 units of the Class 8 all-electric truck per year. While this number may not be attained by the facility right out of the gate, it would only be a matter of time before the factory manages to hit an optimal production rate.

In a video posted on social media earlier this year, Dan Priestley, who leads the Semi program at Tesla stated that the company is preparing for volume production over the coming quarters. With such a pace, the factory should be able to mass produce the Semi in 2026.

Elon Musk confirms Tesla AI6 chip is Project Dojo’s successor

Tesla’s AI5 and AI6 chips are expected to be rolled out to the company’s consumer products.

Earlier this week, reports emerged stating that Tesla has stepped back from its Project Dojo initiative. While the reports were initially framed as a negative development for the electric vehicle maker’s autonomous driving efforts, CEO Elon Musk later noted on X that Tesla was indeed halting its Dojo initiative.

Elon Musk’s Confirmation

As per Musk, Tesla was shuttering Project Dojo because it does not make sense for the company to divide its resources and scale two different AI chip designs. Dojo, after all, is designed to train the company’s autonomous driving program, and thus, it would not be rolled out to Tesla’s consumer products.

In a series of posts on X, Musk stated that it would make sense to just use Tesla’s AI5/AI6 to train its FSD and Autopilot systems. “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 said.

Tesla’s AI5 and AI6 chips are expected to be rolled out to the company’s consumer products, from Optimus to the Cybercab to the next-generation Roadster.

AI6 is Dojo’s Successor

What was particularly interesting about Musk’s comment was his mention of using AI5/AI6 chips for training. As per Musk, this strategy could be seen as “Dojo 3” in a way, since the performance of Tesla’s AI5 and AI6 chips is already notable. Musk’s comment about using AI6 chips for training caught the eye of many, including Apple and Rivian alumnus Phil Beisel, who noted that “AI6 is now Dojo.”

“Dojo is Tesla’s AI training supercomputer, built around a custom chip known as the D1. The D1 and AI5/AI6 share many core design elements, particularly the math operations used in neural networks (e.g., matrix multiplication) and highly parallel processing.

“Dojo had a unique feature: chips arranged in a 5×5 grid using a system-on-wafer design, with etched interconnects enabling high-speed data transfer. In a sense, Dojo will live on as the generalized AI6. Going forward, all efforts will focus on AI6,” the tech veteran wrote in a post on X.

Elon Musk confirmed the Apple alumnus’ musings, with the CEO responding with a “bullseye” emoji. Musk is evidently excited for Tesla’s AI6 chip, which is expected to produced by Samsung’s upcoming Texas fabrication facility. In a post on X, Musk stated that he would personally be walking Samsung’s line to accelerate the output of Tesla’s AI6 computers.

It took a while, but the Tesla Cybertruck’s rock sliders and battery armor upgrades have finally arrived. The upgrade was announced by the electric vehicle maker on social media platform X, to much appreciation from Cybertruck owners.

Tesla Releases Cybertruck Armor Package

As could be seen in Tesla’s official Shop, the Cybertruck Terrestrial Armor Package is available only for Foundation Series units for now, though non-Foundation Series vehicles should have access to the upgrade around September 2025. Price-wise, the armor package is quite reasonable at $3,500.

For that price, Cybertruck owners would be able to acquire enhanced rock sliders and an underbody battery shield that should allow the all-electric pickup truck to go through harsh terrain without any issues. Each purchase of the Terrestrial Armor Package includes 1 Underbody shield, 1 Left side structural rocker, and 1 Right side structural rocker.

Most importantly, the Armor Package’s price includes shipment to the customer’s preferred Tesla Service Center and installation.

Extra-Terrestrial

Tesla describes its Cybertruck Armor Package as follows: “Get extra-terrestrial. The Cybertruck Terrestrial Armor Package includes enhanced rock sliders and an underbody battery shield to provide greater protection from rocks and debris when off-roading on tough terrain. The rock sliders are constructed from coated steel and the underbody battery shield is constructed from aluminum for greater protection against scraping.”
