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.”

How SpaceX Is raising Raptor’s sea-level thrust while holding engine mass steady
SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.
Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.
This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:
🚀 Elon says Raptor 4 will make 300 tons of thrust at sea level at roughly the same mass as Raptor 3.
How far Raptor has come:
Raptor 1: 185 tf, 2,080 kg
Raptor 2: 230 tf, 1,630 kg
Raptor 3: 250 tf, 1,525 kg
Raptor 4: 300 tf33 on Super Heavy = ~9,900 tf, nearly 3x Saturn V https://t.co/HQDswZhyvL

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.
This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.
Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.
Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.
The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.
Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.
For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.
Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.

Tesla Assisted Driving expands to tenth EU country
Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.
Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.
The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.
🚨 Latvia has just received approval for Tesla Full Self-Driving (Supervised)
This is the 10th country in the EU to gain approval:
1. Netherlands — 10 April 2026 (original RDW approval)
2. Lithuania — 20 May 2026
3. Estonia — 29 May 2026
4. Denmark — 9 June 2026
5. Belgium — 10 June 2026
6. Slovenia — 7 September 2026
7. Czechia — 21 September 2026
8. Croatia — 29 September 2026
9. Slovakia — 16 October 2026— TESLARATI (@Teslarati) October 26, 2026
Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.
In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.
The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.
The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.
These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.
However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.

Tesla expands Robotaxi geofence in Houston with an ode to SpaceX merger
Tesla expanded its Robotaxi geofence in Houston, Texas, today, enlarging the service area and drawing a new rocket-shaped boundary across the city’s northwestern and central parts.
Although CEO Elon Musk said it was just a coincidence, the expansion seems to be an ode to SpaceX and its potential merger with Tesla.
🚨 Tesla has just expanded its Robotaxi geofence in Houston
It looks a lot like a rocket — we all remember the shape in Austin 🤣 https://t.co/cFOPEuiJ4u
— TESLARATI (@Teslarati) October 26, 2026
The official Tesla Robotaxi account announced the change with the lines “Houston, we have liftoff” and “Bigger service area now live,” pairing them with a map overlay.
The prior white geofence, roughly 25 square miles covering Jersey Village, Harvest Bend, and the Willowbrook corridor along U.S. 290 and State Highway 249, now sits inside a larger blue zone that stretches southeast toward Bellair and closer to central Houston.
Houston’s Robotaxi service launched on April 18, 2026, the same day as Dallas, as Tesla’s first unsupervised public expansion beyond Austin. From the start, the vehicles were Model Ys running without anyone in the front seats, booked through the dedicated Tesla Robotaxi app and open to the public inside the geofence.
Trackers measured the initial zone at about 25 square miles; by late September it had not grown substantially. Community and registry data indicated a modest local fleet of unsupervised Model Ys, while dozens to nearly 200 Cybercabs, the purpose-built, steering-wheel-free two-seaters, have been spotted staging and testing in Houston lots, though public Cybercab rides remain limited to Austin for now.
Across the broader Robotaxi program, Tesla began public Robotaxi rides in Austin in June 2025, as a small geofence and vehicles with safety monitors became available for a ride-hailing service. Later on, Tesla removed the monitors and steadily expanded the service area until it covered most of the Austin metro area.
Unsupervised Robotaxi services now run in six cities: Austin, Dallas, Houston, Miami, Orlando, and Tampa. Cumulative driverless miles reported by the company have reached several million. The Cybercab entered public service in Austin in early September 2026 and has scaled rapidly there. The company has also said that Dallas is next for Cybercab rides in November, with further cities and 24/7 hours targeted by year-end, plus fleet-operator sales of the vehicle.
Waymo also operates a fully driverless service in Houston, which has been open to the public since August of this year.
The Houston expansion continues Tesla’s pattern of starting with tightly controlled validation zones before widening coverage as real-world data accumulates, while the rocket motif on the map underscores the company’s habit of injecting visual flair into its autonomy rollout.
Riders inside the new boundary can request unsupervised Model Y trips in the Robotaxi app; exact operating hours and further Cybercab availability remain subject to app updates and company statements.
