With all of the Tesla Semi sightings over the past week, it is time to give some attention to the Tesla Megacharger, which will supply the all-electric class 8 truck with range when it is inevitably added to the fleet at Frito Lay in Modesto, California.

While the Semi, and vehicles in general, tends to take center stage over anything, even things remotely related to the vehicle in question, the Megacharger may be a different animal. The massive Semi is a serious challenge as Tesla tries to navigate the fine line between range, hauling, and efficiency in its introductory class-8 vehicle.

The Megacharger has been tasked with providing the Tesla Semi with range before and during its trips. Patents for the Megacharger were released several years ago in 2019 and hinted toward liquid-cooled charging connectors that would pave the way for a fast and efficient charging mechanism providing the Semi with as little as 400 miles of range in just 30 minutes.

The liquid-cooled charging cable would be able to charge the Semi faster because it has the ability to dissipate heat. The patent describes the cooling system:

“Cooling fluid flows through the fluid flow path and cools the charging connector. During operation, the cooling fluid bifurcates into a first fluid stream which flows around the first sleeve, and a second fluid stream which flows around the second sleeve. The first and second fluid streams combine upstream of the outlet conduit. The first sleeve encloses the first electrical socket, and the second sleeve encloses the second electrical socket. The cooling sleeves are made from a thermally conducting material such that heat generated by electrical sockets can be removed by the cooling fluid.”

Tesla’s liquid-cooled charging connector patent paves way for the Semi’s Megachargers

The Megacharger has been spotted several times, but up-close looks have been limited in recent years as: 1) Megachargers are not publicly available for people to walk up to and take pictures of, and 2) the Semi has not yet been delivered to any of its customers, and Tesla is still working on starting production.

Teslarati received exclusive close-up pictures of the Megacharger, showing the charger itself, the charging connector, and the “sleeve.”

At first glance, there have been so many changes since 2017. The charging port on the Semi used to be an 8-pin configuration that is significantly larger than the Supercharger port found on any of Tesla’s other vehicles.

The liquid-cooled charging cable is especially thick and has a weave pattern that is tailored for the high-energy output that the Megacharger will have. The increased thickness and suitable design will help transfer energy faster and decrease charging times, giving the connector the ability to withstand high current loads. This new charging connector alleviates the potential for overheating or slow charging, as the redesigned Megacharger is configured to keep logistics routes moving and drivers on the road.

Tesla has launched a new service designed to make its Full Self-Driving (FSD) technology familiar to all commuters. 

Dubbed the “Tesla Ride” program, the initiative aims to bring supervised Full Self-Driving demos and Grok AI-guided experiences to consumers in real world trips. 

How Tesla Ride Works

As per the official Tesla Ride website, the session will allow participants to sit in the driver’s seat while a Tesla Advisor rides shotgun as co-pilot. The Tesla Advisor then guides riders through the company’s latest supervised FSD features, comfort settings, and in-car entertainment. Participants would also be able to interact with Grok AI in the vehicles. Grok will be capable of answering questions during the ride, and it will even tell stories along the way.

Tesla noted, however, that Tesla Ride sessions are capped at 45 minutes each, and it requires participants to have a valid driver’s license and insurance. Interested participants are also advised to call beforehand so they can schedule their Tesla Rides.

Marketing push and reach

The Tesla Ride program runs across several markets from October into November, and in some locations into the end of December 2025. Participating states are numerous, from Michigan to Virginia to Illiois, Nevada, and California, among others. A look at the official webpage for Tesla Ride shows that the company is still taking a very cautious approach with the program, with disclaimers clearly stating that FSD Supervised does not make Teslas autonomous just yet.

Tesla’s focus on safety with FSD was highlighted recently by Senior Vice President for Automotive Tom Zhu. “Elon said it in 2021: “For self-driving, even if the road is painted completely wrong and a UFO lands in the middle of the road, the car still cannot crash and still needs to do the right thing. 

“The prime directive for the autopilot system is: Don’t crash. That really overrides everything. No matter what the lines say or how the road is done, the thing that needs to happen is minimizing the probability of impact while getting you to your destination conveniently and comfortably,” the executive stated.

Tesla to ramp to 500 Robotaxis in Austin, 1,000 in Bay Area, by end of 2025: Musk

This was, at least, as per recent comments from CEO Elon Musk during his appearance on the All-In podcast.

Tesla’s Robotaxi pilot is still in its early stages, but it seems like the program in Austin and the Bay Area will see a notable update soon. This was, at least, as per recent comments from CEO Elon Musk during his appearance on the All-In podcast. 

Robotaxi expansion

While discussing Tesla’s Robotaxi ambitions, Elon Musk shared some tidbits about the company’s targets for the autonomous ride-hailing program. As per Musk, Tesla is pushing to increase its Robotaxi fleet size in Austin to 500 units. The Robotaxi fleet in the Bay Area will also be increased to 1,000 units. These expansions are expected to be accomplished by the end of the year.

“We’re scaling up the number of cars to, what happens if you have a thousand cars? Probably we’ll have a thousands cars or more in the Bay Area by the end of this year, probably 500 or more in the greater Austin area,” Musk said in the podcast. 

Considering that there are only two months left in the fourth quarter of 2025, Tesla’s Robotaxi team will likely be extremely busy during the next eight weeks. A successful expansion of the Robotaxi pilot in Austin and the Bay Area will also bode well for the company’s ride-hailing program, which has been pretty conservative as of late.

Musk’s Robotaxi comments

Elon Musk has been pretty clear in the past that Tesla’s FSD and Robotaxi network would play a huge role in the company’s future valuation and potential. Thus, during the third quarter earnings call, Musk highlighted that Tesla will also be transitioning to a system with no safety monitors in Austin by the end of the year.

“We are expecting to have no safety drivers in at least large parts of Austin by the end of this year. So within a few months, we expect to have no safety drivers at all in at least parts of Austin. We’re obviously being very cautious about the deployment,” Musk said during the Q3 2025 earnings call.

Neuralink’s first human patient might be in line for a very interesting development in the future.

Based on recent comments from Elon Musk, Neuralink seems to be considering an “upgrade” for its first human patient, allowing him to perform even more sophisticated tasks using only his mind. 

Elon Musk’s recent comments

Musk’s update came as a reply to an X post that featured some details about the current activities of Noland Arbaugh, the first person in the world to receive a Neuralink implant. Since receiving his implant, Arbaugh has been able to take back his life, and he now games, attends class, and even works as a paid speaker. 

In his response, Musk stated that Arbaugh could also be the first Neuralink patient to receive an upgrade. “Noland might be the first to receive a Neuralink upgrade and/or dual Neuralink implant to further augment his abilities. It won’t be long before a Neuralink recipient can beat most and eventually all humans at fast reaction video games,” Musk wrote in a post on X.

Noland’s recent update

Noland actually provided a quick update about his life with his Neuralink implant, which he fondly named Eve, on X. He noted that his direct involvement with Neuralink has lessened as more participants have joined the company’s human trials. And despite a recent pressure sore setback, he remains optimistic and teased “big news” coming for his two-year update in early 2026.

Beyond his recovery, Arbaugh stated that Neuralink has made everyday goals achievable again. He is currently studying neuroscience, taking chemistry, biology, and pre-calculus and maintaining good grades, something he said would have been impossible without Neuralink.
