Tesla Roadster’s ‘SpaceX package’ with rocket thrusters could actually work
This weekend proved to be a fruitful one for Elon Musk’s Twitter followers and fans of the next-generation Tesla Roadster, as the billionaire entrepreneur discussed, in honest-to-goodness seriousness, how the electric car maker would utilize SpaceX technology to make the upcoming all-electric supercar an absolute monster on wheels. Needless to say, there was quite a lot to take in.
Musk started off his Twitter discussion on the next-generation Roadster by stating that the car will feature ~10 rocket thrusters that are “arranged seamlessly around (the) car.” Musk further noted that the thrusters would “dramatically” improve acceleration, braking, and cornering, to the point that the Roadster would be able to fly — a reaffirmation of his previous statement referring to the vehicle having the capability to fly “short hops.”
Musk noted that Tesla would be using SpaceX’s Composite Overwrapped Pressure Vessel (COPV), a container consisting of a thin, non-structural liner wrapped with a structural fiber composite. COPVs are designed to hold a fluid under pressure, and are used by SpaceX’s first-stage rocket boosters during re-entry and landing. Musk further explained the use of SpaceX’s technology in later tweets.
SpaceX option package for new Tesla Roadster will include ~10 small rocket thrusters arranged seamlessly around car. These rocket engines dramatically improve acceleration, top speed, braking & cornering. Maybe they will even allow a Tesla to fly …

While the idea of using rocket propulsion to enhance the performance of an all-electric supercar might seem to be well into the realms of science fiction, using COPVs for the next-gen Roadster is actually pretty feasible, at least from a technical standpoint. SpaceX’s COPVs have operating pressures of around 350 bars (5,000 psi) and too powerful for a land vehicle. If Tesla installs a similar version of SpaceX’s upper stage thrusters that are used in guiding rockets, rear-mounted devices could store just enough compressed air to provide Tesla’s next-gen Roadster an additional boost in acceleration for a short duration.
Note, gas contained would be ultra high pressure air in a SpaceX rocket COPV bottle. The air exiting the thrusters would immediately be replenished whenever vehicle pack power draw allowed operation of the air pump, which is most of the time.

Rocket thrusters placed in front of the vehicle that provides thrust opposite of the Roadster’s direction of travel, at least in concept, could help the electric car’s braking capability, while thrusters placed along each side of the vehicle can help in cornering by providing lateral force. In order to accomplish this, however, Tesla would have to carefully balance the weight of components from the upgraded SpaceX package – Musk noted that the vehicle would sacrifice its rear seats from the standard 2+ 2 configuration to accommodate the additional hardware – with output from the rocket thrusters to maximize the vehicle’s performance. Onboard electric air pumps would repressurize the space-grade containers when they were depleted, making for repeat fun, at least in a theoretical sense. Musk also stated that SpaceX COPVs that will be used for the next-generation Roadster will be durable, and be “literally bulletproof.”
Exactly. Total energy stored even in ultra compressed air is low vs battery, but power output is insane. The composite overwrapped pressure vessel (COPV) is most advanced ever made. It’s what SpaceX is qualifying for NASA crewed missions. Extremely robust — literally bulletproof.

Overall, Musk reiterated that the next-generation Tesla Roadster is designed to be the best car in the industry when it gets released. During his tweetstorm, Musk mentioned that with the all-electric supercar, Tesla is attempting to beat ICE vehicles on “every performance metric;” thus transferring the “halo crown effect” gas cars have as the top speed standards in the automotive market.
New details about Tesla’s next-generation Roadster have been released by Elon Musk lately. The SpaceX option for the vehicle was announced during the 2018 Annual Shareholder Meeting, and not long after that, Musk also revealed that the vehicle would feature an “Augmented Mode” designed to “enhance human driving ability,” thereby providing assistance to drivers who would be operating the insanely powerful supercar.
During the unveiling of the next-generation Tesla Roadster, Elon Musk noted that the purpose of the all-electric supercar is to give a “hardcore smackdown” to gasoline-powered cars. The specs of the vehicle that were unveiled then, which are representative of the all-electric supercar’s base trim, are already record-breaking, including a 0-60 mph time of 1.9 seconds, a quarter-mile time of 8.9 seconds, a top speed of over 250 mph, 620 miles of range thanks to a 200 kWh battery, and 10,000 Nm of torque. With the Roadster’s SpaceX option, the all-electric supercar could very well establish a new class of vehicles that lie beyond the hypercar echelon.
Tesla has introduced an enhanced visualization in its Supercharger navigation system, building directly on the Site Maps feature rolled out a few months ago.
This latest software update adds detailed 3D icons that represent specific vehicle models parked at charging stalls, offering drivers a more precise view of site occupancy and layout.
The Site Maps debuted in Tesla’s 2025 Holiday Update, providing 3D overviews of select Supercharger locations with real-time stall availability.
Tesla supplements Holiday Update by sneaking in new Full Self-Driving version
Drivers could see which spots were open, occupied, or out of service when navigating to supported stations.
Now, the system takes this capability further by rendering accurate representations of Tesla vehicles, including distinctions between models such as the Model 3, Model Y, Model S, Model X, and Cybertruck. These icons appear as lifelike 3D renderings, complete with recognizable shapes and proportions that match the actual cars charging at the site:

This refinement improves the user experience during road trips and daily charging stops. As drivers approach a Supercharger, the navigation display now shows not just generic occupied markers but identifiable vehicle types plugged into each stall.
Blue indicators highlight active charging sessions, while other visual cues denote availability or maintenance status. The feature integrates seamlessly with the existing map interface, allowing quick assessment of the best available spot based on vehicle size and positioning.
Tesla continues to expand the availability of these detailed Site Maps across its global network. Initially piloted at a limited number of locations, the rollout has progressed steadily, with more stations gaining support in recent software versions.
Owners benefit from better planning, as the system helps identify compatible stalls and reduces uncertainty upon arrival. The update reflects Tesla’s ongoing commitment to refining its navigation and charging ecosystem through iterative software improvements.
In addition to model-specific icons, the enhanced maps maintain all prior functionalities, such as integration with nearby amenities and energy usage predictions. This ensures a comprehensive tool for efficient Supercharging.
As Tesla’s fleet grows and the network scales, such features play a key role in optimizing the overall ownership experience. Future updates may extend similar visualizations to additional sites and incorporate even more data points for drivers.
With this piggyback enhancement, Tesla demonstrates how small but thoughtful additions can elevate an already useful tool, making Supercharger visits smoother and more informed for its customers. The company is expected to broaden the feature’s reach in upcoming releases, further solidifying its leadership in EV charging infrastructure.
Tesla Full Self-Driving v14.3.3 driver monitoring was reportedly scaled back in recent releases, but a new version that was released in the early hours of June 3 aimed to do a better job of keeping those in control of their cars honest, according to release notes.
The release notes for FSD v14.3.3, via Software Version 2026.14.6.7 added:
“Improved driver monitoring system sensitivity with better eye gaze tracking, eye wear handling, and higher accuracy in variable lighting conditions.”
However, Tesla said this was already enabled in the first rollout of FSD v14.3.3 in late May. We tested it anyway, especially as the Standard Speed Profile seemed less-than-worried about what you were doing during operation.
I decided to try out the Hurry and Mad Max Speed Profiles for this test, and it gave me results that I would have expected. Tesla has evidently ramped up driver monitoring based on the Speed Profile you are using to travel.
The more aggressive the Speed Profile, the more on the hook you will be for taking your attention away from the road. Our testing showed that Mad Max was less likely to allow you to do normal things like change music or adjust navigation without getting an on-screen warning or nag from the driver monitoring system.
Hurry Mode Results
On Hurry, the driver monitoring system on FSD v14.3.3, via Software Version 2026.14.6.7, was more restrictive than Standard but less restrictive than Mad Max. I found that I could scroll through music options for a considerable amount of time, more than 30 seconds:
Roughly :31 between first touching the center screen and getting the first nag

Standard gave me about 80 seconds of phone scrolling with absolutely no nags or warnings in a previous test. It is worth noting that this was a previous branch of v14.3.3, but Standard is such a goodie-two-shoes on the road that it is my impression it would not change much.
Here’s an 80-second phone nag test on Tesla FSD v14.3.3.

Mad Max Results
I spent the majority of the drive on Mad Max to see how it truly reacted to the driver having their attention elsewhere. While I did do a short phone test, I am aiming to steer away from those and use the center screen. I think it is a valid criticism that the phone test is dangerous and, not to mention, illegal in Pennsylvania. Changing the navigation and music is a more reasonable, more responsible, and safer test.
With Mad Max being the fastest and most aggressive Speed Profile, I anticipated this being the quickest mode to give me an alert that I needed to look at the road. That was the case with music:

As well as adjusting Navigation, when I received two nags:

— TESLARATI (@Teslarati) June 3, 2026
These nags were more than reasonable, and I think it’s probably good that Tesla is ramping up the driver monitoring. I do believe that it should be relatively strict across all of the Speed Profiles, especially with phone use. When using the center screen, the nag intervals should be based on the speed profile you are utilizing at the time.
These driver monitoring adjustments are a great thing to have while FSD is still under its “Supervised” moniker, but I expect Tesla to continue pushing the limits on what it will allow, especially considering CEO Elon Musk has hinted that phone use is capable with the more recent versions.

Tesla has responded to the skeptics of its Robotaxi program by launching a massive expansion of the unsupervised program in its initial rollout city of Austin.
The company’s geofence, the enabled area of operation for rides, now covers the entire Austin Metropolitan area, an incredible move just days after media headlines attempted to discredit the ride-hailing service.
Those who have access to the Tesla Robotaxi app on their smartphones can now request a ride in any portion of the Austin Metro area. The company confirmed this on the social media platform X:
Unsupervised Robotaxi now in the entire Austin Metro area https://t.co/eXNBdarvVS
— Tesla Robotaxi (@robotaxi) June 3, 2026
This is Tesla’s fifth expansion of the geofence, with the others occurring in July, early August, late August, and late October 2025. It has remained at that size since October 26, but Tesla has now more than doubled that size.
It is now covering the entire area, including suburbs like Pflugerville and Manor, as well as I-35 highways, Gigafactory Texas, and the Austin-Bergstrom Airport.
The move comes just days after various media outlets highlighted the small fleet size of Tesla’s Robotaxi fleet in Austin, something that is a reasonable criticism but an understandable move on the company’s part to prioritize safety.
Tesla has expanded its Robotaxi geofence many times, but its fleet has remained at a relatively conservative size as the company continues to push safety as its most crucial metric.
The latest expansion is a key indicator of Tesla’s comfort level to expand the ride-hailing service. The move shows Tesla is scaling unsupervised autonomy, as it demonstrates that the company’s Full Self-Driving system has reached sufficient reliability for a broader real-world deployment, which is something the company has worked on extensively.
It also shows Tesla is game for a competition with its rivals in the autonomous ride-hailing sector. Tesla has often matched or exceeded competitors like Waymo in coverage area, despite its smaller fleet. This step highlights Tesla’s iterative, data-driven progress toward a high-margin, app-based Robotaxi network.
It’s not the absolute largest area expansion ever, but achieving full unsupervised operations across a major metro is a key moment in the Robotaxi story. It shifts the program from limited pilot/testing toward a more mature commercial service, while gathering the miles needed for faster growth.
