Elon Musk shares insights on jet tracker ban, Twitter’s privacy info policy updates
Twitter officially banned the account of jet tracker Jack Sweeney on Wednesday, together with his other accounts that track notable people such as Elon Musk. Sweeney’s ban has been linked to an incident involving Elon Musk’s Baby X, his youngest son with record producer and musician Grimes. Twitter also updated its privacy information policy.
Jack Sweeney’s POV
Jack Sweeney’s Twitter account @ElonJet tracks the routes of the Tesla CEO’s private jet using air traffic data and posts it to the public via the social media platform. On Wednesday, Sweeney stated that his @ElonJet account, his personal account @JxckSweeney, and his other jet trackers were suspended as well. The University of Central Florida college student noted that he would continue tracking Elon Musk’s plane and sharing the information via alternative social media platforms such as Mastodon.
Before his Twitter accounts were suspended, Sweeney’s Musk jet tracker was reportedly shadowbanned. A shadowban makes it difficult for other Twitter users to find an account.
Elon Musk’s POV
Elon Musk shares some insights on why Sweeney’s jet trackers were banned through Twitter recently.
“Any account doxxing real-time location info of anyone will be suspended, as it is a physical safety violation. This includes posting links to sites with real-time location info. Posting locations someone traveled to on a slightly delayed basis isn’t a safety problem, so is ok.
-->“Last night, car carrying lil X in LA was followed by crazy stalker (thinking it was me), who later blocked car from moving & climbed onto the hood. Legal action is being taken against Sweeney & organizations who supported harm to my family,” Musk wrote.
Twitter’s Private Information Policy
Amidst news of Sweeney’s jet trackers’ suspensions, Twitter updated its Private Information Policy, prohibiting anyone from sharing another person’s “live” location “in most cases.”
“When someone shares an individual’s live location on Twitter, there is an increased risk of physical harm. Moving forward, we’ll remove Tweets that share this information, and accounts dedicated to sharing someone else’s live location will be suspended,” Twitter explained.
Twitter users can share their own live location. They can also share the location information of other users as long as it is not on the same day. Twitter permits users to share the location of public gatherings, such as concerts or political events—although it did not clarify if “live” locations are permitted for these types of events.
The updated privacy policy also includes private media images or videos of private individuals without their consent. Although, this part of the policy seems to have leeway since Twitter recognizes that “there are instances where users may share images or videos of private individuals, who are not public figures, as part of a newsworthy event.”
-->The Main Issues
- What is freedom of speech?
- Does freedom of speech have limits?
- What is privacy for public figures?
- Does affiliation with a public figure affect a person’s right to privacy?
Before acquiring Twitter, Elon Musk claimed that he wanted the platform to be a space that promotes freedom of speech. The billionaire used Sweeney’s @ElonJet account to highlight that he was committed to free speech on Twitter. At the time, Musk acknowledged that @ElonJet was a “direct personal safety risk.”
While Musk may have accepted the risk to his own safety by keeping Sweeney’s account live, his family might be a different matter. The same may go for the other people who Sweeney kept tabs on through his Twitter accounts.
However, Musk was not the only one at fault here. Sweeney’s jet tracker supposedly provides the potential locations of public figures. However, it is not always clear-cut. In the Baby X incident, for example, the alleged perpetrator may have thought that the @ElonJet account was making Musk’s potential location public, not his son’s.
The information Sweeney dispenses might be too ambiguous, and may lead to many misunderstandings. For instance, earlier this year, Taylor Swift made headlines after Yard calculated that her flight emissions were 1,184.8 times more than the average person’s. Yard based its calculations on Sweeney’s @CelebJets account. While the figure might seem shocking, a spokesperson for Swift explained that the pop star loans her jet out regularly, so Yard’s findings were argued as “blatantly incorrect.”

Tesla is improving Giga Berlin’s free “Giga Train” service for employees
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
Tesla will expand its factory shuttle service in Germany beginning January 4, adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg in Grünheide.
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
New shuttle route
As noted in a report from rbb24, the updated service, which will start January 4, will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory Berlin complex. Tesla stated that the timetable mirrors shift changes for the facility’s employees, and similar to before, the service will be completely free. The train will offer six direct trips per day as well.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany stated.
Even with construction continuing at Fangschleuse and Köpenick stations, the company said the route has been optimized to maintain a predictable 35-minute travel time. The update follows earlier phases of Tesla’s “Giga Train” program, which initially connected Erkner to the factory grounds before expanding to Berlin-Lichtenberg.
-->Tesla pushes for majority rail commuting
Tesla began production at Grünheide in March 2022, and the factory’s workforce has since grown to around 11,500 employees, with an estimated 60% commuting from Berlin. The facility produces the Model Y, Tesla’s best-selling vehicle, for both Germany and other territories.
The company has repeatedly emphasized its goal of having more than half its staff use public transportation rather than cars, positioning the shuttle as a key part of that initiative. In keeping with the factory’s sustainability focus, Tesla continues to allow even non-employees to ride the shuttle free of charge, making it a broader mobility option for the area.

Tesla Model 3 and Model Y dominate China’s real-world efficiency tests
The Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km.
Tesla’s Model 3 and Model Y once again led the field in a new real-world energy-consumption test conducted by China’s Autohome, outperforming numerous rival electric vehicles in controlled conditions.
The results, which placed both Teslas in the top two spots, prompted Xiaomi CEO Lei Jun to acknowledge Tesla’s efficiency advantage while noting that his company’s vehicles will continue refining its own models to close the gap.
Tesla secures top efficiency results
Autohome’s evaluation placed all vehicles under identical conditions, such as a full 375-kg load, cabin temperature fixed at 24°C on automatic climate control, and a steady cruising speed of 120 km/h. In this environment, the Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km, as noted in a Sina News report.
These figures positioned Tesla’s vehicles firmly at the top of the ranking and highlighted their continued leadership in long-range efficiency. The test also highlighted how drivetrain optimization, software management, and aerodynamic profiles remain key differentiators in high-speed, cold-weather scenarios where many electric cars struggle to maintain low consumption.
Xiaomi’s Lei Jun pledges to continue learning from Tesla
Following the results, Xiaomi CEO Lei Jun noted that the Xiaomi SU7 actually performed well overall but naturally consumed more energy due to its larger C-segment footprint and higher specification. He reiterated that factors such as size and weight contributed to the difference in real-world consumption compared to Tesla. Still, the executive noted that Xiaomi will continue to learn from the veteran EV maker.
“The Xiaomi SU7’s energy consumption performance is also very good; you can take a closer look. The fact that its test results are weaker than Tesla’s is partly due to objective reasons: the Xiaomi SU7 is a C-segment car, larger and with higher specifications, making it heavier and naturally increasing energy consumption. Of course, we will continue to learn from Tesla and further optimize its energy consumption performance!” Lei Jun wrote in a post on Weibo.
-->Lei Jun has repeatedly described Tesla as the global benchmark for EV efficiency, previously stating that Xiaomi may require three to five years to match its leadership. He has also been very supportive of FSD, even testing the system in the United States.

Elon Musk reveals what will make Optimus’ ridiculous production targets feasible
Musk recent post suggests that Tesla has a plan to attain Optimus’ production goals.
Elon Musk subtly teased Tesla’s strategy to achieve Optimus’ insane production volume targets. The CEO has shared his predictions about Optimus’ volume, and they are so ambitious that one would mistake them for science fiction.
Musk’s recent post on X, however, suggests that Tesla has a plan to attain Optimus’ production goals.
The highest volume product
Elon Musk has been pretty clear about the idea of Optimus being Tesla’s highest-volume product. During the Tesla 2025 Annual Shareholder Meeting, Musk stated that the humanoid robot will see “the fastest production ramp of any product of any large complex manufactured product ever,” starting with a one-million-per-year line at the Fremont Factory.
Following this, Musk stated that Giga Texas will receive a 10 million-per-year unit Optimus line. But even at this level, the Optimus ramp is just beginning, as the production of the humanoid robot will only accelerate from there. At some point, the CEO stated that a Mars location could even have a 100 million-unit-per-year production line, resulting in up to a billion Optimus robots being produced per year.
Self-replication is key
During the weekend, Musk posted a short message that hinted at Tesla’s Optimus strategy. “Optimus will be the Von Neumann probe,” the CEO wrote in his post. This short comment suggests that Tesla will not be relying on traditional production systems to make Optimus. The company probably won’t even hire humans to produce the humanoid robot at one point. Instead, Optimus robots could simply produce other Optimus robots, allowing them to self-replicate.
-->The Von Neumann is a hypothetical self-replicating spacecraft proposed by the mathematician and physicist John von Neumann in the 1940s–1950s. The hypothetical machine in the concept would be able to travel to a new star system or location, land, mine, and extract raw materials from planets, asteroids, and moons as needed, use those materials to manufacture copies of itself, and launch the new copies toward other star systems.
If Optimus could pull off this ambitious target, the humanoid robot would indeed be the highest volume product ever created. It could, as Musk predicted, really change the world.
