Elon Musk pegs SpaceX BFR program at $5B as NASA’s rocket booster nears $5B in cost overruns
At the same time as NASA’s overrun-stricken Space Launch System (SLS) continues to limp towards its continuously delayed launch debut, now tentatively expected no earlier than (NET) 2021, SpaceX is forging ahead with the development of an equivalently capable launch vehicle known as BFR, comprised of a spaceship (BFS) and booster (BFB).
During a September 17th update to the next-gen SpaceX rocket’s steady progress, CEO Elon Musk offered a rough cost estimate of $5B to complete its development – no less than $2B and no more than $10B. According to NASA’s Office of the Inspector General (OIG), Boeing – primary contractor for NASA’s SLS “Core Stage” or booster – is all but guaranteed to burn through a minimum of $8.9B between 2012 and the rocket’s tentative 2021 launch debut.
NASA is finally (officially) acknowledging that EM-1, the maiden launch of SLS, will slip until at least June 2020. Sources tell us to expect another slip to 2021, official or not.https://t.co/CYf9SqbhBY

Originally contracted in 2014 to complete SLS booster development, production, and preparation by 2018 at a cost of $4.2B, Boeing has overrun its budget by a bit less than 50% (up to $6.2B) and overshot its scheduled launch debut by more than 2.5 years. Per an October 10th audit of the SLS booster program, NASA OIG has reasonably concluded that Boeing will pass that $6.2B expenditure estimate – meant to last until 2021 – in December 2018, meaning that at least an additional $2.7B will be required from NASA between now and 2021 if SLS is to have a chance at launching that year.
In other words, compared to Boeing’s first serious 2014 contract for the SLS Core Stages – $4.2B to complete Core Stages 1 and 2 and launch EM-1 in Nov. 2017 – the company will ultimately end up 215% over-budget ($4.2B to $8.9B) and ~40 months behind schedule (42 months to 80+ months from contract award to completion). Meanwhile, as OIG notes, NASA has continued to give Boeing impossibly effusive and glowing performance reviews to the tune of $323 million in “award fees”, with grades that would – under the contracting book NASA itself wrote – imply that Boeing SLS Core Stage work has been reliably under budget and ahead of schedule (it’s not).

The “Satisfactory” Stuff
In reality, Boeing has not once been under budget or ahead of schedule during any of 6+ NASA performance reviews.
“Boeing should have received a “satisfactory” rating for [two review periods]; a “good” rating for [one review period]; and an “unsatisfactory” rating (no award fee) for [the 2017 review period].”
Instead, NASA has given Boeing three “Very Good” (nearly perfect) reviews and three “Excellent” (perfect) reviews over the last 6 years, ultimately dispersing $323M of pure-profit “award fees” thanks to those grades, while the OIG firmly disputes Boing’s worthiness for at least $65M of that sum.
It is pretty pathetic when the only response that @BoeingSpace can muster via @BKingDC at its #politicospace PR effort in response to a damning @NASA_SLS report by @NASAOIG is to dump on the Saturn V – a rocket that actually flew – and worked – half a century ago. https://t.co/daN91bzwpC

Boeing – recently brought to light as the likely source of a spate of egregiously counterfactual op-eds published with the intention of dirtying SpaceX’s image – also took it upon itself to sponsor what could be described as responses to NASA OIG’s scathing October 10th SLS audit. Hilariously, a Politico newsletter sponsored by Boeing managed to explicitly demean and belittle the Apollo-era Saturn V rocket as a “rickety metal bucket built with 1960s technology”, of which Boeing was the core stage’s prime contractor.
At the same time, that newsletter described SLS as a rocket that will be “light years ahead of thespacecraft [sic] that NASA astronauts used to get to the moon 50 years ago.” At present, the only clear way SLS is or will be “light years” ahead – as much a measure of time as it is of distance – of Saturn V is by continuing the rocket’s trend of endless delays. Perhaps NASA astronomers will soon be able to judge exactly how many “light years ahead” SLS is by measuring the program’s redshift or blueshift with one of several ground- and space-based telescopes.
Ultimately, this is a particularly effective bit of self-mockery in the context of rationale lately used by Boeing and NASA to shrug off the jaw-dropping Core Stage contract’s underperformance, missteps, schedule slips, and budget overruns, namely that building big, complex rockets is hard. NASA and Boeing, neither of which have any meaningful experience building big, complex rockets – aside from Saturn IB, Saturn V, and the Space Shuttle – thus should be given a break for reliably and dramatically underestimating the difficulties of doing so in the 21st century.
One of the most breathtaking things about the new SLS report is the response by NASA's Gerstenmaier. Essentially, he says, this a is a big, complex rocket. And it's hard to build this stuff.https://t.co/ou8SFhji6a

Simultaneously, Boeing and NASA still continue to act as if they are the foremost global experts of building extremely large rockets and continue to throw pile upon pile of taxpayer billions at overpromised attempts to prove as much. It’s no more than a masochistic dream to imagine what could have been or might be if NASA instead redirected those billions towards US aerospace companies with track records of success through fixed-cost contracts or straight-up private funding (SpaceX and Blue Origin, primarily), but it’s often hard not to at least think about the possibilities.

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.
