SpaceX President explains termination of employees behind open letter criticizing Elon Musk’s tweets
Recently, news broke that some SpaceX employees have written an open letter criticizing CEO Elon Musk’s behavior on Twitter. The employees have been terminated by the private space firm, with SpaceX President Gwynne Shotwell explaining the rationale behind the company’s decision.
The open letter argued that SpaceX is not living up its “No Asshole” and zero-tolerance sexual harassment policies due to Elon Musk’s behavior. The open letter demanded that SpaceX should “publicly address and condemn Elon’s harmful Twitter behavior,” among others. “Elon’s behavior in the public sphere is a frequent source of distraction and embarrassment for us, particularly in recent weeks,” the letter read.
In her letter to SpaceX employees, Shotwell clarified that the people behind the open letter had been terminated. She noted that SpaceX had received complaints from several employees who complained about the open letter because the initiative made them feel “uncomfortable, intimidated and bullied, and/or angry because the letter pressured them to sign onto something that did not reflect their views.”
Shotwell also highlighted that the letter interfered with workers’ ability to focus on their work, especially amidst SpaceX’s busy schedule. “We have too much critical work to accomplish and no need for this kind of overreaching activism — our current leadership team is more dedicated to ensuring we have a great and ever-improving work environment than any I have seen in my 35-years career,” she wrote.
Following is Shotwell’s letter to SpaceX employees about the matter:
You may have received an unsolicited request from a small group of SpaceX employees for your signature on an “open letter” yesterday and your participation in a related survey. Based on diverse employee feedback, this has upset many. That is, the letter, solicitations and general process made employees feel uncomfortable, intimidated and bullied, and/or angry because the letter pressured them to sign onto something that did not reflect their views.
Employees also complained that it interfered with their ability to focus on and do their work. We have 3 launches within 37 hours for critical satellites this weekend, we have to support the astronauts we delivered to the ISS and get cargo Dragon back to the flight-ready, and after receiving environmental approval early this week, we are on the cusp of the first orbital launch attempt of Starship. We have too much critical work to accomplish and no need for this kind of overreaching activism — our current leadership team is more dedicated to ensuring we have a great and ever-improving work environment than any I have seen in my 35-years career.
We solicit and expect our employees to report all concerns to their leadership, senior management, HR, or Legal. But blanketing thousands of people across the company with repeated unsolicited emails and asking them to sign letters and fill out unsponsored surveys during the work day is unacceptable, goes against our documented handbook policy, and does not show the strong judgement needed to work in this very challenging space transportation sector. We performed an investigation and have terminated a number of employees involved.
I am sorry for this distraction. Please stay focused on the SpaceX mission, and use your time at work to do your best work. This is how we will get to Mars.
The open letter of SpaceX employees about Elon Musk’s behavior can be viewed below.
An open letter to the Executives of SpaceX,
In light of recent allegations against our CEO and his public disparagement of the situation, we would like to deliver feedback on how these events affect our company’s reputation, and through it, our mission. Employees across the spectra of gender, ethnicity, seniority, and technical roles have collaborated on this letter. We feel it is imperative to maintain honest and open dialogue with each other to effectively reach our company’s primary goals together: making SpaceX a great place to work for all, and making humans a multiplanetary species.
As SpaceX employees we are expected to challenge established processes, rapidly innovate to solve complex problems as a team, and use failures as learning opportunities. Commitment to these ideals is fundamental to our identity and is core to how we have redefined our industry. But for all our technical achievements, SpaceX fails to apply these principles to the promotion of diversity, equity, and inclusion with equal priority across the company, resulting in a workplace culture that remains firmly rooted in the status quo.
Individuals and groups of employees at SpaceX have spent significant effort beyond their technical scope to make the company a more inclusive space via conference recruiting, open forums, feedback to leadership, outreach, and more. However, we feel an unequal burden to carry this effort as the company has not applied appropriate urgency and resources to the problem in a manner consistent with our approach to critical path technical projects. To be clear: recent events are not isolated incidents; they are emblematic of a wider culture that underserves many of the people who enable SpaceX’s extraordinary accomplishments. As industry leaders, we bear unique responsibility to address this.
Elon’s behavior in the public sphere is a frequent source of distraction and embarrassment for us, particularly in recent weeks. As our CEO and most prominent spokesperson, Elon is seen as the face of SpaceX—every Tweet that Elon sends is a de facto public statement by the company. It is critical to make clear to our teams and to our potential talent pool that his messaging does not reflect our work, our mission, or our values.
SpaceX’s current systems and culture do not live up to its stated values, as many employees continue to experience unequal enforcement of our oft-repeated “No Asshole” and “Zero Tolerance” policies. This must change. As a starting point, we are putting forth the following categories of action items, the specifics of which we would like to discuss in person with the executive team within a month:
Publicly address and condemn Elon’s harmful Twitter behavior. SpaceX must swiftly and explicitly separate itself from Elon’s personal brand.
Hold all leadership equally accountable to making SpaceX a great place to work for everyone. Apply a critical eye to issues that prevent employees from fully performing their jobs and meeting their potential, pursuing specific and enduring actions that are well resourced, transparent, and treated with the same rigor and urgency as establishing flight rationale after a hardware anomaly.
Define and uniformly respond to all forms of unacceptable behavior. Clearly define what exactly is intended by SpaceX’s “no-asshole” and “zero tolerance” policies and enforce them consistently. SpaceX must establish safe avenues for reporting and uphold clear repercussions for all unacceptable behavior, whether from the CEO or an employee starting their first day.
We care deeply about SpaceX’s mission to make humanity multiplanetary. But more importantly, we care about each other. The collaboration we need to make life multiplanetary is incompatible with a culture that treats employees as consumable resources. Our unique position requires us to consider how our actions today will shape the experiences of individuals beyond our planet. Is the culture we are fostering now the one which we aim to bring to Mars and beyond?
We have made strides in that direction, but there is so much more to accomplish.

Tesla refines Full Self-Driving, latest update impresses where it last came up short
We were able to go out and test it pretty extensively on Saturday, and the changes Tesla made from the previous version were incredibly impressive, especially considering it seemed to excel where it last came up short.
Tesla released Full Self-Driving v14.2.1.25 on Friday night to Early Access Program (EAP) members. It came as a surprise, as it was paired with the release of the Holiday Update.
We were able to go out and test it pretty extensively on Saturday, and the changes Tesla made from the previous version were incredibly impressive, especially considering it seemed to excel where it last came up short.
Tesla supplements Holiday Update by sneaking in new Full Self-Driving version
With Tesla Full Self-Driving v14.2.1, there were some serious regressions. Speed Profiles were overtinkered with, causing some modes to behave in a strange manner. Hurry Mode was the most evident, as it refused to go more than 10 MPH over the speed limit on freeways.
It would routinely hold up traffic at this speed, and flipping it into Mad Max mode was sort of over the top. Hurry is what I use most frequently, and it had become somewhat unusable with v14.2.1.
It seemed as if Speed Profiles should be more associated with both passing and lane-changing frequency. Capping speeds does not help as it can impede the flow of traffic. When FSD travels at the speed of other traffic, it is much more effective and less disruptive.
With v14.2.1.25, there were three noticeable changes that improved its performance significantly: Speed Profile refinements, lane change confidence, and Speed Limit recognition.
🚨 Many of you asked us to test highway driving with Tesla Full Self-Driving v14.2.1.25. Here’s what we noticed:

Speed Profile Refinement
Speed Profiles have been significantly improved. Hurry Mode is no longer capped at 10 MPH over the speed limit and now travels with the flow of traffic. This is much more comfortable during highway operation, and I was not required to intervene at any point.
With v14.2.1, I was sometimes assisting it with lane changes, and felt it was in the wrong place at the wrong time more frequently than ever before.
However, this was one of the best-performing FSD versions in recent memory, and I really did not have any complaints on the highway. Speed, maneuvering, lane switching, routing, and aggressiveness were all perfect.
Lane Changes
v14.2.1 had a tendency to be a little more timid when changing lanes, which was sort of frustrating at times. When the car decides to change lanes and turn on its signal, it needs to pull the trigger and change lanes.
It also changed lanes at extremely unnecessary times, which was a real frustration.
There were no issues today on v14.2.1.25; lane changes were super confident, executed at the correct time, and in the correct fashion. It made good decisions on when to get into the right lane when proceeding toward its exit.
It was one of the first times in a while that I did not feel as if I needed to nudge it to change lanes. I was very impressed.
Speed Limit Recognition
So, this is a complex issue. With v14.2.1, there were many times when it would see a Speed Limit sign that was not meant for the car (one catered for tractor trailers, for example) or even a route sign, and it would incorrectly adjust the speed. It did this on the highway several times, mistaking a Route 30 sign for a 30 MPH sign, then beginning to decelerate from 55 MPH to 30 MPH on the highway.
This required an intervention. I also had an issue leaving a drive-thru Christmas lights display, where the owners of the private property had a 15 MPH sign posted nearly every 200 yards for about a mile and a half.
The car identified it as a 55 MPH sign and sped up significantly. This caused an intervention, and I had to drive manually.
It seems like FSD v14.2.1.25 is now less reliant on the signage (maybe because it was incorrectly labeling it) and more reliant on map data or the behavior of nearby traffic.
A good example was on the highway today: despite the car reading that Route 30 sign and the Speed Limit sign on the center screen reading 30 MPH, the car did not decelerate. It continued at the same speed, but I’m not sure if that’s because of traffic or map data:
🚨 We listened to and read a lot of you who had a complaint of Tesla Full Self-Driving v14.2.1 incorrectly reading Speed Limit signs
This appears to be resolved in v14.2.1.25.

A Lone Complaint
Tesla has said future updates will include parking improvements, and I’m really anxious for them, because parking is not great. I’ve had some real issues with it over the past couple of months.
Today was no different:
🚨 My lone complaint with my drive on Tesla FSD v14.2.1.25 was this strange parking instance.
FSD swung out wide to the left to pull into this spot and this is where it seemed to be stumped. I gave it about 10 seconds after the car just stopped moving for it to make some… https://t.co/ZEkhTHOihG pic.twitter.com/TRemXu5DLf

Full Self-Driving v14.2.1.25 is really a massive improvement over past versions, and it seems apparent that Tesla took its time with fixing the bugs, especially with highway operation on v14.2.1.

Tesla hints at Starlink integration with recent patent
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”
Tesla hinted at a potential Starlink internet terminal integration within its vehicles in a recent patent, which describes a vehicle roof assembly with integrated radio frequency (RF) transparency.
The patent, which is Pub. No U.S. 2025/0368267 describes a new vehicle roof that is made of RF-transparent polymer materials, allowing and “facilitating clear communication with external devices and satellites.”
Tesla believes that a new vehicle roof design, comprised of different materials than the standard metallic or glass elements used in cars today, would allow the company to integrate modern vehicular technologies, “particularly those requiring radio frequency transmission and reception.
Tesla has recently filed a US patent application on integrating RF transparent materials into the roof structure.

Instead of glass or metallic materials, Tesla says vehicles may benefit from high-strength polymer blends, such as Polycarbonate, Acrylonitrile Butadiene Styrene, or Acrylonitrile Styrene Acrylate.
These materials still provide ideal strength metrics for crashworthiness, stiffness for noise, vibration, and harshness control, and are compliant with head impact regulations.
They would also enable better performance with modern technologies, like internet terminals, which need an uninterrupted signal to satellites for maximum reception. Tesla writes in the patent:
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”
One of the challenges Tesla seems to be aware of with this type of roof design is the fact that it will still have to enable safety and keep that at the forefront of the design. As you can see in the illustration above, Tesla plans to use four layers to increase safety and rigidity, while also combating noise and vibration.
It notes in the patent that disclosed examples still meet the safety requirements outlined in the Federal Motor Vehicle Safety Standards (FMVSS).
Starlink integrated directly into Tesla vehicles would be a considerable advantage for owners. It would come with a handful of distinct advantages.
Initially, the inclusion of Starlink would completely eliminate cellular dead zones, something that is an issue, especially in rural areas. Starlink would provide connectivity in these remote regions and would ensure uninterrupted service during road trips and off-grid adventures.
It could also be a critical addition for Robotaxi, as it is crucial to have solid and reliable connectivity for remote monitoring and fleet management.
Starlink’s growing constellation, thanks to SpaceX’s routine and frequent launch schedule, will provide secure, stable, and reliable internet connectivity for Tesla vehicles.
Although many owners have already mounted Starlink Mini dishes under their glass roofs for a similar experience, it may be integrated directly into Teslas in the coming years, either as an upgrade or a standard feature.

Tesla supplements Holiday Update by sneaking in new Full Self-Driving version
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla has surprised some owners by sneaking in a new Full Self-Driving version with the wide release of the Holiday Update, which started rolling out to Hardware 4 owners on Friday night.
Tesla has issued a controlled and very slow release pattern with the Holiday Update, which rolls out with Software Version 2025.44.25.5.
For the past two weeks, as it has rolled out to Hardware 3 and older Tesla owners, the company has kept its deployment of the new Software Version relatively controlled.
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla Full Self-Driving v14.2.1.25 made its first appearance last night to Hardware 4 owners who are members of the Early Access Program (EAP). It appears to be a slight refinement from FSD v14.2.1, which has been out for a couple of weeks.

Many owners welcome the new FSD version, us included, because we’ve been less than impressed with v14.2.1. We have experienced some minor regressions with v14.2.1, especially with Speed Limit recognition, Speed Profile tinkering, and parking performance.
As it stands, Full Self-Driving is still particularly impressive, but Tesla is evidently having an issue with some of the adjustments, as it is still refining some of the performance aspects of the suite. This is expected and normal with some updates, as not all of them are an improvement in all areas; we routinely see some things backtrack every once in a while.
This new FSD version is likely to take care of those things, but it also includes all of the awesome Holiday Update features, which include:
- Grok with Navigation Commands (Beta) – Grok will now add and edit destinations.
- Tesla Photobooth – Take pictures inside your car using the cabin-facing camera
- Dog Mode Live Activity – Check on your four-legged friend on your phone through periodic snapshots taken of the cabin
- Dashcam Viewer Update – Includes new metrics, like steering wheel angle, speed, and more
- Santa Mode – New graphics, trees, and a lock chime
- Light Show Update – Addition of Jingle Rush light show
- Custom Wraps and License Plates – Colorizer now allows you to customize your vehicle even further, with custom patterns, license plates, and tint
- Navigation Improvements – Easier layout and setup
- Supercharger Site Map – Starting at 18 pilot locations, a 3D view of the Supercharger you’re visiting will be available
- Automatic Carpool Lane Routing – Navigation will utilize carpool lanes if enabled
- Phone Left Behind Chime – Your car will now tell you if you left a phone inside
- Charge Limit Per Location – Set a charge limit for each location
- ISS Docking Simulator – New game
- Additional Improvements – Turn off wireless charging pad, Spotify improvements, Rainbow Rave Cave, Lock Sound TRON addition
Tesla also added two other things that were undocumented, like Charging Passport and information on USB drive storage to help with Dashcam.
