SpaceX CEO Elon Musk wants to use Starships as Earth-to-Earth transports
SpaceX CEO Elon Musk indicates that the company is analyzing the use of single-stage Starship spacecraft as a potential pillar of its rapid Earth-to-Earth transport ambitions, meant to realize hypersonic mass-transit at “business-class” prices.
The consequences of such a move are varied but the gist is fairly simple: by cutting down on the complexity of the hardware and infrastructure involved, Earth-based transport via reusable rockets immediately becomes a far more intriguing (and plausible) proposition. Huge challenges remain, but many of those challenges could potentially become identical to those that Starship must already face to achieve SpaceX’s ultimate goal of Mars colonization.
As discussed on Teslarati just ~24 hours ago, using extremely large rockets to quickly, reliably, and safely transport humans around the Earth sounds great on paper but runs into a huge number of brick walls after just a cursory analysis. The single most important aspect of any high-volume form of mass transit is passenger safety – if a method consistently demonstrates that it is likely to kill passengers, it will die a very quick death to public opinion and regulatory fury.
From a statistical standpoint, rockets are thousands of times less safe than passenger aircraft, in large part due to their complexity and cost. As it turns out, an almost invariably foolproof method of improving the safety of a given thing is reducing its complexity (within moderation, of course). The fewer the parts there are, the fewer the parts that can fail and the easier (and cheaper) gathering data and evidence will be.
Originally, SpaceX’s 2017 Earth-to-Earth concept relied on a full two-stage BFR rocket (now Starship/Super Heavy) that could transport passengers anywhere on Earth in 30-60 minutes. Expected to launch off of giant, floating platforms, boosters would launch and land on the same platform while sending Starships on there way around the world. Starships would head to identical platforms at their destination and land directly beside that platform’s booster.
In general, this concept at least seemed serviceable, even if it didn’t exactly scream “practical solution!” Thankfully, much like BFR itself has radically changed in the last 18 or so months, it appears that SpaceX’s concept of Starship-based Earth transportation services has also continued to evolve. According to Musk’s May 30th tweets on the subject, one obvious method of improving the viability of the concept involves entirely removing the booster (Super Heavy) from the picture.
In an instant, SpaceX’s concept of Earth-to-Earth transport starts to look more like an exotic version of proposed supersonic and hypersonic transport solutions. By leaning on lone Starship spacecraft, incapable of reaching orbit by themselves, Musk believes that SpaceX could transport passengers up to ~10,000 km at speeds as high as “Mach 20” (6.9 km/s, 15,500 mph). This is undeniably a downgrade from “anywhere on Earth in less than an hour”, but it would still easily trounce any existing mode of transport and could potentially lend itself to actual suborbital spaceports located in key areas.
At the speeds described, SpaceX could offer ~20-minute trips from New York City to London or ~40-minute trips from Los Angeles to Tokyo as just two examples. Lack of range would certainly limit the potential utility and ubiquity of such a transport service, but there are undeniably enough niche markets to sustain something like that. By relying entirely on Starship, transportation could become far similar to airliner-style travel, while keeping speeds well below orbital velocity would give the spacecraft’s heat shield a much easier time.
For now, at least, the SpaceX dream of global, hypersonic mass-transit is clearly still alive and well, even if the hurdles ahead of it remain no less imposing. According to President and COO Gwynne Shotwell, SpaceX could begin offering Earth-to-Earth transport services as early as 2025, if not earlier with Musk’s proposed Starship-only variant.

What is Digital Optimus? The new Tesla and xAI project explained
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Tesla and xAI announced their groundbreaking joint project, Digital Optimus, also nicknamed “Macrohard” in a humorous jab at Microsoft, earlier this week.
This software-based AI agent is designed to automate complex office workflows by observing and replicating human interactions with computers. As the first major outcome of Tesla’s $2 billion investment in xAI, it represents a powerful fusion of hardware efficiency and advanced reasoning.
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Macrohard or Digital Optimus is a joint xAI-Tesla project, coming as part of Tesla’s investment agreement with xAI.

Tesla’s specialized AI acts as “System 1”—the fast, instinctive executor—processing the past five seconds of real-time computer screen video along with keyboard and mouse actions to perform immediate tasks.
xAI’s Grok model serves as “System 2,” the strategic “master conductor” or navigator, providing high-level reasoning, world understanding, and directional oversight, much like an advanced turn-by-turn navigation system.
When combined, the two can create a powerful AI-based assistant that can complete everything from accounting work to HR tasks.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
The system runs primarily on Tesla’s low-cost AI4 inference chip, minimizing expensive Nvidia resources from xAI for competitive, real-time performance.
Elon Musk described it as “the only real-time smart AI system” capable, in principle, of emulating the functions of entire companies, handling everything from accounting and HR to repetitive digital operations.
Timelines point to swift deployment. Announced just days ago, Musk expects Digital Optimus to be ready for user experience within about six months, targeting rollout around September 2026.
It will integrate into all AI4-equipped Tesla vehicles, enabling parked cars to handle office work during downtime. Millions of dedicated units are also planned for deployment at Supercharger stations, tapping into roughly 7 gigawatts of available power.
Oh and it works in all AI4-equipped cars, so your car can do office work for you when not driving.
We’re also deploying millions of dedicated Digital Optimus units in the field at Superchargers where we have ~7 gigawatts of available power.

Digital Optimus directly supports Tesla’s broader autonomy strategy. It leverages the same end-to-end neural networks, computer vision, and real-time decision-making tech that power Full Self-Driving (FSD) software and the physical Optimus humanoid robot.
By repurposing idle vehicle compute and extending AI4 hardware beyond driving, the project scales Tesla’s autonomy ecosystem from roads to digital workspaces.
As a virtual counterpart to physical Optimus, it divides labor: software agents manage screen-based tasks while humanoid robots tackle physical ones, accelerating Tesla’s vision of general-purpose AI for productivity, Robotaxi fleets, and beyond.
In essence, Digital Optimus bridges Tesla’s vehicle and robotics autonomy with enterprise-scale AI, promising massive efficiency gains. No other company currently matches its real-time capabilities on such accessible hardware.
It really could be one of the most crucial developments Tesla and xAI begin to integrate, as it could revolutionize how people work and travel.

Tesla adds awesome new driving feature to Model Y
Tesla is rolling out a new “Comfort Braking” feature with Software Update 2026.8. The feature is exclusive to the new Model Y, and is currently unavailable for any other vehicle in the Tesla lineup.
Tesla is adding an awesome new driving feature to Model Y vehicles, effective on Juniper-updated models considered model year 2026 or newer.
Tesla is rolling out a new “Comfort Braking” feature with Software Update 2026.8. The feature is exclusive to the new Model Y, and is currently unavailable for any other vehicle in the Tesla lineup.
Tesla writes in the release notes for the feature:
“Your Tesla now provides a smoother feel as you come to a complete stop during routine braking.”

Interestingly, we’re not too sure what catalyzed Tesla to try to improve braking smoothness, because it hasn’t seemed overly abrupt or rough from my perspective. Although the brake pedal in my Model Y is rarely used due to Regenerative Braking, it seems Tesla wanted to try to make the ride comfort even smoother for owners.
There is always room for improvement, though, and it seems that there is a way to make braking smoother for passengers while the vehicle is coming to a stop.
This is far from the first time Tesla has attempted to improve its ride comfort through Over-the-Air updates, as it has rolled out updates to improve regenerative braking performance, handling while using Full Self-Driving, improvements to Steer-by-Wire to Cybertruck, and even recent releases that have combatted Active Road Noise.
Tesla holds a unique ability to change the functionality of its vehicles through software updates, which have come in handy for many things, including remedying certain recalls and shipping new features to the Full Self-Driving suite.
Tesla seems to have the most seamless OTA processes, as many automakers have the ability to ship improvements through a simple software update.
We’re really excited to test the update, so when we get an opportunity to try out Comfort Braking when it makes it to our Model Y.

Tesla finally brings a Robotaxi update that Android users will love
The breakdown of the software version shows that Tesla is actively developing an Android-compatible version of the Robotaxi app, and the company is developing Live Activities for Android.
Tesla is finally bringing an update of its Robotaxi platform that Android users will love — mostly because it seems like they will finally be able to use the ride-hailing platform that the company has had active since last June.
Based on a decompile of software version 26.2.0 of the Robotaxi app, Tesla looks to be ready to roll out access to Android users.
According to the breakdown, performed by Tesla App Updates, the company is preparing to roll out an Android version of the app as it is developing several features for that operating system.
🚨 It looks like Tesla is preparing to launch the Robotaxi app for Android users at last!

The breakdown of the software version shows that Tesla is actively developing an Android-compatible version of the Robotaxi app, and the company is developing Live Activities for Android:
“Strings like notification_channel_robotaxid_trip_name and android_native_alicorn_eta_text show exactly how Tesla plans to replicate the iOS Live Activities experience. Instead of standard push alerts, Android users are getting a persistent, dynamically updating notification channel.”
This is a big step forward for several reasons. From a face-value perspective, Tesla is finally ready to offer Robotaxi to Android users.
The company has routinely prioritized Apple releases because there is a higher concentration of iPhone users in its ownership base. Additionally, the development process for Apple is simply less laborious.
Tesla is working to increase Android capabilities in its vehicles
Secondly, the Robotaxi rollout has been a typical example of “slowly then all at once.”
Tesla initially released Robotaxi access to a handful of media members and influencers. Eventually, it was expanded to more users, so that anyone using an iOS device could download the app and hail a semi-autonomous ride in Austin or the Bay Area.
Opening up the user base to Android users may show that Tesla is preparing to allow even more users to utilize its Robotaxi platform, and although it seems to be a few months away from only offering fully autonomous rides to anyone with app access, the expansion of the user base to an entirely different user base definitely seems like its a step in the right direction.
