Tesla’s Battery Day is only a few days away, and as the event draws closer, it appears that the electric car maker is starting to make its “Roadrunner” site as presentable as possible to its visitors. As could be seen in a recent drone flyover of the pilot battery cell production site, the surroundings of the Kato Road building are now being cleared of materials and equipment, likely in preparation for Battery Day.
The Kato Road facility holds one of the most highly-anticipated segments of the upcoming Battery Day event. During the event, Tesla is expected to discuss the work that it has been doing with its battery tech over the years. Much of these developments have been heavily speculated, with reports indicating that Tesla will be discussing the development and capabilities of its next-generation cells, which could last a million miles on the road or decades if used as energy storage units.
But beyond these discussions, Battery Day will also involve a tour of Tesla’s “Roadrunner” site, which is located in Kato Road, close to the Fremont factory. The full details of the “Roadrunner” site have not been discussed by Tesla so far, though reports and filings about the site have suggested that the location holds the pilot production line for the electric car maker’s own custom-designed cells.
Interestingly enough, a recent leak reported in EV publication Electrek hinted at what the “Roadrunner” battery cells could possibly look like. Images leaked to the publication featured a rather hefty cell that is far larger than the 18650 and 2170 batteries being used by Tesla in its existing electric vehicle lineup. Observations and basic analyses from Tesla community members with a background in battery technology have pointed to the “Roadrunner” cell potentially adopting a 54×98 form factor.
If these speculations are accurate, Tesla may be going for complete EV domination with its next-generation batteries. Battery cells that adopt the 54×98 form factor hold about 10 times the volume of a 2170 cell, and according to Jordan Giesige of The Limiting Factor channel on YouTube, this presents several advantages for the electric car maker. With the larger cells, for example, Tesla could equip its vehicles with an order of magnitude fewer cells than before, resulting in massive savings in production costs.
These speculations will likely be proven or debunked this coming Battery Day, which is scheduled for this coming Tuesday, September 22, 2020. Regardless of this, however, the Kato Road facility is poised to get even busier in the near future. As noted in filings to the City of Fremont, the “Roadrunner” site will be housing 45 research and development employees and up to 425 manufacturing workers that are spread through several shifts from Monday to Friday. This should make the “Roadrunner” facility humming along nicely, and perhaps even producing enough cells for low-volume vehicles like the Plaid Model S, Plaid Model X, and the next-generation Roadster.

Anti-Tesla union leader ditches X, urges use of Threads instead
Tesla Sweden and IF Metall have been engaged in a bitter dispute for over two years now.
Marie Nilsson, chair of Sweden’s IF Metall union and a prominent critic of Tesla, has left X and is urging audiences to follow the union on Meta’s Threads instead.
Tesla Sweden and IF Metall have been engaged in a bitter dispute for over two years now.
Anti-Tesla union leader exits X
In a comment to Dagens Arbete (DA), Nilsson noted that her exit from X is not formally tied to IF Metall’s long-running labor dispute with Tesla Sweden. Still, she stated that her departure is affected by changes to the platform under Elon Musk’s leadership.
“We have stayed because many journalists pick up news there. But as more and more people have left X, we have felt that the standard has now been reached on that platform,” she said.
Jesper Pettersson, press officer at IF Metall, highlighted that the union’s departure from X is only indirectly linked to Tesla Sweden and Elon Musk. “Indirectly it does, since there is a lot of evidence that his ownership has caused the change in the platform to be so significant.
“We have nevertheless assessed that the platform had value for reaching journalists, politicians and other opinion leaders. But it is a microscopic proportion of the public and our members who are there, and now that value has decreased,” Petterson added.
IF Metall sees Threads as an X alternative
After leaving X, IF Metall has begun using Threads, Meta’s alternative to the social media platform. The union described the move as experimental, noting that it is still evaluating how effective the platform will be for outreach and visibility.
Pettersson acknowledged that Meta also does not operate under Sweden’s collective bargaining model, but said the union sees little alternative if it wants to remain visible online.
“In a perfect world, all large international companies would be supporters of the Swedish model when they come here. But unfortunately, the reality is not like that. If we are to be visible at all in this social media world, we have to play by the rules of the game. The alternative would be to become completely invisible, and that would not benefit our members,” he said.
Despite many recent rumors and various reports, Elon Musk confirmed today that SpaceX is not developing a phone based on Starlink, not once, but twice.
Today’s report from Reuters cited people familiar with the matter and stated internal discussions have seen SpaceX executives mulling the idea of building a mobile device that would connect directly to the Starlink satellite constellation.
Musk did state in late January that SpaceX developing a phone was “not out of the question at some point.” However, He also said it would have to be a major difference from current phones, and would be optimized “purely for running max performance/watt neural nets.”
Not out of the question at some point. It would be a very different device than current phones. Optimized purely for running max performance/watt neural nets.

While Musk said it was not out of the question “at some point,” that does not mean it is currently a project SpaceX is working on. The CEO reaffirmed this point twice on X this afternoon.
Musk said, “Reuters lies relentlessly,” in one post. In the next, he explicitly stated, “We are not developing a phone.”

Musk has basically always maintained that SpaceX has too many things going on, denying that a phone would be in the realm of upcoming projects. There are too many things in the works for Musk’s space exploration company, most notably the recent merger with xAI.

A Starlink phone would be an excellent idea, especially considering that SpaceX operates 9,500 satellites, serving over 9 million users worldwide. 650 of those satellites are dedicated to the company’s direct-to-device initiative, which provides cellular coverage on a global scale.
Nevertheless, there is the potential that the Starlink phone eventually become a project SpaceX works on. However, it is not currently in the scope of what the company needs to develop, so things are more focused on that as of right now.
Tesla has added a notable improvement to its Dashcam feature after complaints from owners have pushed the company to make a drastic change.
Perhaps one of the biggest frustrations that Tesla owners have communicated regarding the Dashcam feature is the lack of ability to retain any more than 60 minutes of driving footage before it is overwritten.
It does not matter what size USB jump drive is plugged into the vehicle. 60 minutes is all it will hold until new footage takes over the old. This can cause some issues, especially if you were saving an impressive clip of Full Self-Driving or an incident on the road, which could be lost if new footage was recorded.
This has now been changed, as Tesla has shown in the Release Notes for an upcoming Software Update in China. It will likely expand to the U.S. market in the coming weeks, and was first noticed by NotaTeslaApp.
The release notes state:
“Dashcam Dynamic Recording Duration – The dashcam dynamically adjusts the recording duration based on the available storage capacity of the connected USB drive. For example, with a 128 GB USB drive, the maximum recording duration is approximately 3 hours; with a 1 TB or larger USB drive, it can reach up to 24 hours. This ensures that as much video as possible is retained for review before it gets overwritten.”
Tesla Adds Dynamic Recording
Instead of having a 60-minute cap, the new system will now go off the memory in the USB drive. This means with:
- 128 GB Jump Drive – Up to Three Hours of Rolling Footage
- 1TB Jump Drive – Up to 24 Hours of Rolling Footage
This is dependent on the amount of storage available on the jump drive, meaning that if there are other things saved on it, it will take away from the amount of footage that can be retained.
While the feature is just now making its way to employees in China, it will likely be at least several weeks before it makes its way to the U.S., but owners should definitely expect it in the coming months.
It will be a welcome feature, especially as there will now be more customization to the number of clips and their duration that can be stored.
