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 Full Self-Driving (FSD) testing gains major ground in Spain
Based on information posted by the Dirección General de Tráfico (DGT), it appears that Tesla is already busy testing FSD in the country.
Tesla’s Full Self-Driving (Supervised) program is accelerating across Europe, with Spain emerging as a key testing hub under the country’s new ES-AV framework program.
Based on information posted by the Dirección General de Tráfico (DGT), it appears that Tesla is already busy testing FSD in the country.
Spain’s ES-AV framework
Spain’s DGT launched the ES-AV Program in July 2025 to standardize testing for automated vehicles from prototypes to pre-homologation stages. The DGT described the purpose of the program on its official website.
“The program is designed to complement and enhance oversight, regulation, research, and transparency efforts, as well as to support innovation and advancements in automotive technology and industry. This framework also aims to capitalize on the opportunity to position Spain as a pioneer and leader in automated vehicle technology, seeking to provide solutions that help overcome or alleviate certain shortcomings or negative externalities of the current transportation system,” the DGT wrote.
The program identifies three testing phases based on technological maturity and the scope of a company’s operations. Each phase has a set of minimum eligibility requirements, and applicants must indicate which phase they wish to participate in, at least based on their specific technological development.

Tesla FSD tests
As noted by Tesla watcher Kees Roelandschap on X, the DGT’s new framework effectively gives the green flight for nationwide FSD testing. So far, Tesla Spain has a total of 19 vehicles authorized to test FSD on the country’s roads, though it would not be surprising if this fleet grows in the coming months.
The start date for the program is listed at November 27, 2025 to November 26, 2027. The DGT also noted that unlimited FSD tests could be done across Spain on any national route. And since Tesla is already in Phase 3 of the ES-AV Program, onboard safety operators are optional. Remote monitoring would also be allowed.
Tesla’s FSD tests in Spain could help the company gain a lot of real-world data on the country’s roads. Considering the scope of tests that are allowed for the electric vehicle maker, it seems like Spain would be one of the European countries that would be friendly to FSD’s operations. So far, Tesla’s FSD push in Europe is notable, with the company holding FSD demonstrations in Germany, France, and Italy. Tesla is also pushing for national approval in the Netherlands in early 2026.

Tesla FSD V14.2.1 is earning rave reviews from users in diverse conditions
Tesla’s Full Self-Driving (Supervised) software continues its rapid evolution, with the latest V14.2.1 update drawing widespread praise.
Tesla’s Full Self-Driving (Supervised) software continues its rapid evolution, with the latest V14.2.1 update drawing widespread praise for its smoother performance and smarter decision-making.
Videos and firsthand accounts from Tesla owners highlight V14.2.1 as an update that improves navigation responsiveness, sign recognition, and overall fluidity, among other things. Some drivers have even described it as “more alive than ever,” hinting at the system eventually feeling “sentient,” as Elon Musk has predicted.
FSD V14.2.1 first impressions
Early adopters are buzzing about how V14.2.1 feels less intrusive while staying vigilant. In a post shared on X, Tesla owner @LactoseLunatic described the update as a “huge leap forward,” adding that the system remains “incredibly assertive but still safe.”
Another Tesla driver, Devin Olsenn, who logged ~600 km on V14.2.1, reported no safety disengagements, with the car feeling “more alive than ever.” The Tesla owner noted that his wife now defaults to using FSD V14, as the system is already very smooth and refined.
Adverse weather and regulatory zones are testing grounds where V14.2.1 shines, at least according to testers in snow areas. Tesla watcher Sawyer Merritt shared a video of his first snowy drive on unplowed rural roads in New Hampshire, where FSD did great and erred on the side of caution. As per Merritt, FSD V14.2.1 was “extra cautious” but it performed well overall.
-->Sign recognition and freeway prowess
Sign recognition also seemed to show improvements with FSD V14.2.1. Longtime FSD tester Chuck Cook highlighted a clip from his upcoming first-impressions video, showcasing improved school zone behavior. “I think it read the signs better,” he observed, though in standard mode, it didn’t fully drop to 15 mph within the short timeframe. This nuance points to V14.2.1’s growing awareness of temporal rules, a step toward fewer false positives in dynamic environments.
FSD V14.2.1 also seems to excel in high-stress highway scenarios. Fellow FSD tester @BLKMDL3 posted a video of FSD V14.2.1 managing a multi-lane freeway closure due to a police chase-related accident. “Perfectly handles all lanes of the freeway merging into one,” the Tesla owner noted in his post on X.
FSD V14.2.1 was released on Thanksgiving, much to the pleasant surprise of Tesla owners. The update’s release notes are almost identical to the system’s previous iteration, save for one line item read, “Camera visibility can lead to increased attention monitoring sensitivity.”

Tesla FSD Supervised ride-alongs in Europe begin in Italy, France, and Germany
The program allows the public to hop in as a non-driving observer to witness FSD navigate urban streets firsthand.
Tesla has kicked off passenger ride-alongs for Full Self-Driving (Supervised) in Italy, France and Germany. The program allows the public to hop in as a non-driving observer to witness FSD navigate urban streets firsthand.
The program, detailed on Tesla’s event pages, arrives ahead of a potential early 2026 Dutch regulatory approval that could unlock a potential EU-wide rollout for FSD.
Hands-Off Demos
Tesla’s ride-along invites participants to “ride along in the passenger seat to experience how it handles real-world traffic & the most stressful parts of daily driving, making the roads safer for all,” as per the company’s announcement on X through its official Tesla Europe & Middle East account.
Sign-ups via localized pages offer free slots through December, with Tesla teams piloting vehicles through city streets, roundabouts and highways.
“Be one of the first to experience Full Self-Driving (Supervised) from the passenger seat. Our team will take you along as a passenger and show you how Full Self-Driving (Supervised) works under real-world road conditions,” Tesla wrote. “Discover how it reacts to live traffic and masters the most stressful parts of driving to make the roads safer for you and others. Come join us to learn how we are moving closer to a fully autonomous future.”
-->Building trust towards an FSD Unsupervised rollout
Tesla’s FSD (Supervised) ride-alongs could be an effective tool to build trust and get regular car buyers and commuters used to the idea of vehicles driving themselves. By seating riders shotgun, Tesla could provide participants with a front row seat to the bleeding edge of consumer-grade driverless systems.
FSD (Supervised) has already been rolled out to several countries, such as the United States, Canada, Australia, New Zealand, and partially in China. So far, FSD (Supervised) has been received positively by drivers, as it really makes driving tasks and long trips significantly easier and more pleasant.
FSD is a key safety feature as well, which became all too evident when a Tesla driving on FSD was hit by what seemed to be a meteorite in Australia. The vehicle moved safely despite the impact, though the same would likely not be true had the car been driven manually.
