Tesla is adding another tent to its Fremont Factory property, but it will not directly be used for production. Along with the new tent, Tesla has filed for several other things at Fremont, including Model S and Model X manufacturing line upgrades, and an update to the battery equipment production line project that Teslarati revealed in late August.
A new tent at Fremont, but not for production
Tesla has long utilized a heavy-duty tent known as a Sprung Structure for the production of the Model 3 and Model Y. Tesla has two of these “tents” on the Fremont property that it uses for automotive production, which are commonly referred to as General Assembly 4 and General Assembly 4.5.
The tents were initially thought to be a temporary place for production, but Tesla has since kept the structures built. In February 2021, Teslarati showed that Tesla filed with the City of Fremont to make the GA 4.5 tent permanent. The automaker applied for foundation implementations and permits to install below-ground utilities under the structure. It was part of a 64,000-square foot expansion of GA 4.5, as the Model Y had become Tesla’s most popular vehicle. It was also the only factory building the Model Y at the time.
Tesla has now filed to build yet another “temporary exterior tent,” according to filings seen by Teslarati. The company does not plan to utilize it for automotive production, at least not directly. Instead, the tent will provide coverage for tools, likely so they can be moved outside the production space but still be nearby and protected. The project’s cost is listed as $140,000.
Space and storage have been an issue for Tesla at the Fremont factory. A Morgan Stanley note from earlier this year indicated that Tesla was extremely confined in the factory, and expansion seemed like the only obvious option.
Tesla is considering a significant expansion of its Fremont Factory
Of course, Tesla is expanding with other factories, but Fremont is its longest-standing automotive manufacturing property. It is the only factory Tesla has producing all four vehicles, and the company has discussed expanding the property considerably. Elon Musk said earlier this year that Tesla was considering making the factory larger to accommodate more production. Teslarati reported on filings and drone footage that revealed Tesla may be taking early steps to make Fremont considerably larger so it can build more vehicles.
Battery Manufacturing Equipment Line Update
In late August, we reported that Tesla had filed to build a battery manufacturing equipment line on the second floor of the Fremont Factory. The project was valued at $1.5 million.
Tesla said in the filing:
“NEW BATTERY MANUFACTURING EQUIPMENT LINE ON 2ND FLOOR OF MAIN ASSEMBLY BUILDING. THIS PERMIT APPLICATION RELATES TO THE MODULE PORTION OF THE LINE.”
Another filing with the City of Fremont reveals Tesla is making progress on the project. It is now moving forward with the site plan, including the equipment layout, exhaust, power for the equipment, and a process piping plan. Tesla reiterated this project is taking place on the second floor:
“This project is located on the second floor of assembly building. Package will include equipment layout, tool anchorage plan, exhaust, power for equipment, and process piping plan.”
This filing is separate from the previous one and also has a cost of $1.5 million.
Model S and Model X manufacturing equipment upgrades
Tesla has also made numerous upgrades on the Model S and Model X production lines. On August 23, Tesla installed new rocker cell tools, and associated utilities which are automated arms used in production.
On September 20, Tesla also filed to install a new SubFrame Lift Assist, which “will help improve production associates’ ergonomic safety,” the automaker said in the filing.

Tesla has expanded the footprint of a massive safety feature worldwide with a recent Software Update labeled as 2026.20.6. The expansion of the “Blind Spot Warning While Parked” feature represents the more widespread availability of the feature, which aims to prevent “dooring.”
Dooring is when a driver or passenger opens a car door into the path of an oncoming road user, usually a cyclist or motorcyclist. It is among the most common types of cycling accidents, the League of American Bicyclists says.
For this reason, Tesla created a feature that warns occupants not to open the door because an object is approaching. The feature will sound a chime, and it will also delay the opening of the door to prevent an incident.
The release notes state (via Not a Tesla App):
“If you attempt to open a door while an approaching object is detected in your blind spot (for example, a bicyclist approaching from behind) a chime sounds, and your door will not open upon initial button press. Wait a short time and press the button a second time to override the warning.”
Tesla initially rolled out this feature back in 2024 with the Model 3 “Highland.” However, it remained with the Model 3 exclusively for over a year; that was until Tesla added it to the Cybertruck this past Spring.
Now, it is making its way to the new Model Y, 2021 and newer Model S, and 2021 or newer Model X.
The prevention of dooring incidents could eliminate many injuries to cyclists, especially in an urban setting. Dooring accounts for 10-20 percent of bike-related crashes in major cities, and over 17,000 dooring-related incidents were treated in the U.S. over the course of a decade. These usually involve fractures, contusions, and head trauma.
Tesla confirmed this morning that it has sent the first production units, manufactured with no steering wheel or pedals, to on-road testing in Austin, sharing video of the first rides with no human controls.
The lack of steering wheels and pedals in the Cybercab aligns with Tesla’s self-certification of Robotaxi as Level 4 SAE, a platform it plans to make widespread through internal vehicles and customer-owned cars that will operate and generate revenue for individuals.
The start of these engineering tests is a major signal for Tesla, which plans to bring driverless, wheel-less, and pedal-less Cybercabs to market in the coming months. With production already well underway at Gigafactory Texas, where the Cybercab is built, there is some inclination to believe the first public rides could happen sooner rather than later.

Tesla’s engineering tests will put the Cybercab in real-world scenarios, testing not only the hardware, but more importantly, the software that drives the car around Austin with nobody supervising it within the car.
This is perhaps the biggest part of the internal testing process, especially prior to allowing regular, everyday people to hail the Cybercab for an autonomous ride. These early rides serve as a true benchmark for Tesla: How many rides can it achieve safely? How many miles did it travel consecutively without needing an intervention? What scenarios challenge the Full Self-Driving suite the most?
The proper precautions have already been put into place as well, as Tesla released the First Responders Guide to Cybercab over the weekend, ensuring that emergency services have 24/7 access to Robotaxi Assistance, as well as other boundaries, such as Geofencing features that can be used to redirect autonomous vehicle traffic due to accidents, road closures, construction, or maintenance.
Cybercab seems genuinely close to being added to the Robotaxi fleet in Austin, but Tesla has prioritized safety throughout this entire process. Therefore, we think it could be months before it truly starts giving rides to the public. People have been frustrated with this, but Robotaxi in Austin has a tremendous safety record so far, so the slow rollout has kept people safe and accidents to a minimum.
The most important thing is that Tesla continues to show consistent progress in the Cybercab’s ramp-up toward fleet addition. A few weeks back, we saw the EPA reward the Cybercab a Certificate of Conformity, allowing it to enter the stream of commerce. Then, we saw Tesla add decals, signaling that it was likely about to start testing it publicly. That has now happened.
The next big move will be the announcement of the first rides, so this Summer should be filled with anticipation.
For years, there have been images and videos across social media platforms that have reminded me of when I was a 15-year-old kid teased by “Xbox 720” videos on YouTube. These videos are of the supposed “Tesla Phone” that Elon Musk was secretly developing in between leading Tesla with its electric cars and SpaceX with its reusable rockets.

Although Musk has put those rumors to bed several times, it was never completely out of the realm that he could get involved in cell phones in some capacity. Think outside the box and more macro-level, though. Instead of reinventing the computer, Musk reinvented connectivity by developing Starlink with SpaceX.
It could be something similar, TD Cowen analyst Gregory Williams said in a note last week, where he hinted SpaceX could be gathering some steam to acquire T-Mobile.
Williams said it would be the “clear choice” for SpaceX if it decided to go through with a network acquisition. He also suggested AT&T.
The move would be possible through selling more of its own stock, which would help SpaceX raise the money to purchase T-Mobile, which would cost roughly $300 billion. It could be one of the moves SpaceX makes post-IPO in terms of an acquisition: it already acquired Cursor AI for $60 billion.
Other analysts, like Dan Ives of Wedbush, believe SpaceX and Tesla will eventually merge into one anyway, and that conglomeration could come as soon as this year, some have said.
The implications of SpaceX purchasing T-Mobile are massive. A combined entity would create a truly ubiquitous network: T-Mobile’s terrestrial 5G towers and Starlink’s growing constellation of Direct-to-Cell satellites. This would essentially eliminate dead zones across the U.S. and potentially globally.
SpaceX would instantly become a full-scale facilities-based carrier with satellite differentiation; a huge advantage. This would pressure AT&T and Verizon heavily.
There are also concerns like a potential reduction in long-term competition, and of course, a deal of that size would face intense scrutiny from government agencies.
The strategic fit is compelling due to the existing Starlink–T-Mobile partnership and complementary technologies (space + terrestrial). It could create a dominant integrated communications player. However, the regulatory, financial, and execution hurdles are enormous — this remains highly speculative with no indication SpaceX is actively pursuing it right now.
