Tesla Motors Service Centers Make a Pit Stop
Before I mention the pit crew like experience, I do want to mention that one of the most awesome parts of the Tesla service experience is the offer to valet your car at home.

During the earnings conference call with Elon Musk and team in early August, Musk mentioned that Tesla Motors service centers are implementing a Formula One pit crew approach for Model S owners here in the U.S and in China.
In August, Musk said:
“So we actually bring the car and we kind of hit with a pit crew, like a Formula One pit crew. So instead of having one person per bay, the car gets slowly worked on over several days, it actually comes in and a team attacks it, and we’re constantly improving the tools and the metrics to say, how can we get the car perfect as fast as possible. We actually bring in people from Formula One to help with the training on this. And I think there’s a real opportunity to revolutionize the way service works.”
So how is Tesla Motors new Formula One approach working and what has the service center experience been, in general, for the young automaker?
Recently, I interviewed Model S 85 owner, David Zygmont, about his trips to Tesla Motors service centers over the last two years, the Model S service package and has he seen this Formula One approach in action. The slightly edited interview is below:
Grant Gerke: What actually made you decide to buy the service package, which includes 4 service visits in four years or 50,000 miles?
David Zygmont: So being an early adopter, being a really early product for a really young company, I think it was pretty realistic that there would be some need for service and I had hoped like, ‘Wouldn’t it be great if this all electric car would be really maintenance free, free of some real critical headaches.’ However, I should really expect some software glitches, right? I mean this car runs software for everything and I was expecting there to be quite a number of those initially.
So, I feel like there is still a bunch of inconsistencies regarding when to bring in the car. Some service centers report that you really only need to come every 12 months and some say you still need to do it every 12,500 miles. My service center in Highland Park, Ill., says it’s every 12,500 miles.
And, there’s no ambiguity in the contract as it ends at 50,000 miles or four years, whichever you reach soonest. So, I’m going to get maximum value because I’m almost at 20,000 to 25,000 miles a year, somewhere in that range. I need to do it every 12,500 to get maximum value of this, I’ve already been three times for a service checkup.
Grant Gerke: What’s your service center experience been like, so far?
David Zygmont: I’ve had a pretty long relationship, a number of visits with Tesla service and for the most part, the people are really great. I really like working with people, especially the group that I worked with over the last nine to twelve months.
However, they don’t really share a lot in terms of documentation with these annual checkups. When you look at the paperwork, it says: We did an annual service and the parts used are batteries for the fobs and wipers for your windshield.
And I was like, “Okay, great.” That’s my $600?
Some of those visits have also included a number of other line items that I feel like some would happen whether I have the annual service or not because some of them were kind of classified as these service bulletins, which I think is very standard industry practice to say: hey, when your car is in, if we see this as a concern, because your VIN is labeled as… it may have this concern. So they look and if they see the concern, they fix it, and I’ve been very appreciative.
Other non-scheduled service center visits have included parts replaced and they’ve all been driven by some sort of failure and/or observation on my part that says this doesn’t feel right, and Tesla Motors has said either: We agree and made the repairs or they’ve said no to and I totally think that’s reasonable. An example would be Tesla considers it a wear issue, but some would also consider a design issue about why the wear is happening.
Also, I think the service center communication systems and behaviors that’s been implemented as a team have greatly evolved. Early on, I had services where I didn’t hear for three days and I’m like: what’s happened to my car?
But now it’s just amazing service as I receive multiple text message updates per day when they have my car. All my recent service has been same-day stuff and they’ve done it really quickly, maybe that’s reflective of their Formula 1 approach.

Grant Gerke: Speaking of Formula One, what about this pit crew approach? Any signs of it in recent visits?
David Zygmont: Before I mention the pit crew like experience, I do want to mention that one of the most awesome parts of the Tesla service experience is the offer to valet your car at home. So, it entails the service center coming to your house and bringing a Model S loaner and leaving it with you. Then they bring it back all fixed, serviced and whatever that’s been done with it. No one else does that. So, I just want to quickly make mention of that.
But sometimes it actually works better in my day if I could just exchange with (a car) the service center on my way to work. Recently, I was waiting to pick up my car after some service and a car had just come off of a flatbed in front of the Highland Park shop. I watched as a pit crew went to work on that car immediately. It was four service guys–four technicians–and someone was in the driver seat with their laptop in front of them, plugged in on the side port of the Model S. Other team members had covers off, under the hood and they pulled some covers to access some different parts in the front area.
It was really clear that this was like all hands on deck, let’s triage this real fast. I thought that was pretty cool.
What about everyone else? What were some of your expectations for Tesla Motors service centers?
I want to thank Dave for his time and be sure to check out my podcast with Dave Zygmont’s road warrior adventures in his Model S 85 across the supercharger network, “Podcast | Dial-in a Model S Road Trip with These Tips.“

Tesla’s last chance version of the flagship Model X is officially gone
The Signature Edition was no ordinary Model X Plaid. Offered exclusively by invitation to select existing Tesla owners, it represented the final production batch of the current-generation Model X before manufacturing at Fremont ends.
Tesla enabled a last-chance version of its two flagship vehicles, the Model S and Model X, over the past few weeks. The Model X, the company’s original SUV, is officially gone.
Tesla has officially closed the book on its most exclusive send-off for the Model X. The limited-run Model X Signature Edition—priced at $159,420 before fees and limited to just 100 units—is now sold out, with reservations closed as of April 16.

The Signature Edition was no ordinary Model X Plaid. Offered exclusively by invitation to select existing Tesla owners, it represented the final production batch of the current-generation Model X before manufacturing at Fremont ends.
Every unit featured an exclusive Garnet Red exterior paint, unique badging, and a standard six-seat configuration. With full Plaid powertrain specs—Tri-Motor All-Wheel Drive, over 1,000 horsepower, and blistering acceleration—it was positioned as a collector’s item for loyalists who wanted one last shot at owning a piece of Tesla history.
The timing is no coincidence.
Tesla announced earlier this year that it would discontinue regular production of both the Model S and Model X to repurpose the Fremont factory’s dedicated lines for mass production of its Optimus humanoid robots.
Elon Musk has repeatedly emphasized that Optimus could ultimately become more valuable to the company than its vehicle business, with ambitions to build hundreds of thousands of units annually.
The Signature Editions served as a final “runout” series: 250 for the Model S and only 100 for the Model X, all built to the highest Plaid specification before the line is converted.
Deliveries of the remaining Signature units are scheduled to begin in May 2026. For buyers who secured one, it’s the ultimate swan song for a vehicle that helped define Tesla’s early luxury EV dominance.
Launched in 2015, the Model X introduced falcon-wing doors, a panoramic windshield, and class-leading performance that turned heads and set benchmarks. While newer models like the Cybertruck and refreshed Model Y have taken center stage, the Model X Plaid remained a halo product for those seeking maximum range, space, and speed in an SUV package.
With inventory of standard Model X units already nearly exhausted across the U.S., the rapid sell-out of the Signature Edition underscores enduring demand for Tesla’s premium flagships even as the company pivots toward robotics and autonomy.
For enthusiasts, these 100 garnet-red SUVs will likely become instant collector’s items—tangible reminders of the vehicles that built the brand before Tesla’s next chapter fully begins. The last chance is gone, but the legacy endures.

Tesla Optimus V3 hand and arm details revealed in new patents
Two new patents, which were coincidentally filed on the same day as the “We, Robot” event back in October 2024, protect Tesla’s mechanically actuated, tendon-driven architecture.
Tesla is planning to soon reveal its latest and greatest version of the Optimus humanoid robot, and a series of new patents for the hands and arms, with the former being, admittedly, one of the most challenging parts of developing the project.
Two new patents, which were coincidentally filed on the same day as the “We, Robot” event back in October 2024, protect Tesla’s mechanically actuated, tendon-driven architecture.
The designs relocate heavy actuators to the forearm, route cables through a sophisticated wrist design, and employ innovative joint assemblies to achieve human-like dexterity while enabling lightweight construction and high-volume manufacturing.
Core Tendon-Driven Hand Architecture
The primary patent, which is titled “Mechanically Actuated Robotic Hand,” details a cable/tendon-driven system.
Actuators are positioned in the forearm rather than the hand. Each finger features four degrees of freedom (DoF), while the wrist adds two more.
Tesla’s Optimus V3 robot hand looks to have been revealed in a new international patent published today.
The patent describes a tendon/cable-driven hand:
• Actuators in the forearm
• Each finger has 4 degrees of freedom
• The wrist has 2 degrees of freedom
• Tendon-driven… pic.twitter.com/eE8xLEYSrx— Sawyer Merritt (@SawyerMerritt) April 16, 2026
Three thin, flexible control cables (tendons) per finger extend from the forearm actuators, pass through the wrist, and connect to the finger segments. Integrated channels within the finger phalanges guide these cables selectively—routing behind some joints and forward of others—to enable independent bending without unintended motion.
Patent diagrams illustrate thick cable bundles emerging from the wrist into the palm and fingers, with labeled pivots and routing guides. This setup closely mirrors human forearm-muscle and tendon anatomy, where most hand control originates proximally.
Advanced Wrist Routing Innovation
One of the standout features is the wrist’s cable transition mechanism. Cables shift from a lateral stack on the forearm side to a vertical stack on the hand side through a specialized transition zone.
Boom! @Tesla_Optimus 의 3세대 구조로 추정되는, 로봇 팔 및 관절에 대한 특허가 공개되었습니다.
아티클 작업에 들어가겠습니다.
1년 넘게 기다려 온, 정말 귀한 특허인데, 조회수 100만대로 터져줬으면 좋겠네요. 😉@herbertong @SawyerMerritt@GoingBallistic5 @TheHumanoidHub pic.twitter.com/CCEiIlMFSX

This geometry significantly reduces cable stretch, torque, friction, and crosstalk during combined yaw and pitch wrist movements — common failure points in simpler tendon systems that cause imprecise or jerky motion.
By minimizing these issues, the design supports smoother, more reliable multi-axis wrist operation, essential for complex real-world tasks.
Companion Patents on Appendage and Joint Design
Two supporting patents provide additional depth. “Robotic Appendage” covers the overall forearm-to-palm-to-finger assembly, with a palm body movably coupled to the forearm and finger phalanges linked by tensile cables returning to forearm actuators. Tensioning these cables repositions the phalanges precisely.
“Joint Assembly for Robotic Appendage” describes curved contact surfaces on mating structures paired with a composite flexible member. This allows smooth pivoting while maintaining consistent tension, enhancing durability, and simplifying assembly for mass production.
Executive Insights on Hand Development Challenges
Tesla executives have consistently described the hand as the most difficult component of Optimus.
Elon Musk has called it “the majority of the engineering difficulty of the entire robot,” emphasizing that human hands possess roughly 27–28 DoF with an intricate tendon network powered largely by forearm muscles. He has likened the challenge to something “harder than Cybertruck or Model X… somewhere between Model X and Starship.”
In mid-2025, Musk acknowledged that Tesla was “struggling” to finalize the hand and forearm design. By early 2026, he stated that the company had overcome the “hardest” problems, including human-level manual dexterity, real-world AI integration, and volume production scalability.
He estimated the electromechanical hand represents about 60 percent of the overall Optimus challenge, compounded by the lack of an existing supply chain for such precision components.
These patents directly tackle the acknowledged pain points: relocating actuators reduces hand mass and inertia for better speed and efficiency; advanced wrist routing and joint geometry address friction and crosstalk; and simplified, stackable parts visible in the diagrams indicate readiness for high-volume manufacturing.
Implications for Optimus Production and Leadership
Collectively, the patents portray the Optimus v3 hand not as a mere prototype, but as a production-oriented system engineered from first principles.
The 22-DoF architecture, forearm-driven tendons, and crosstalk-minimizing wrist deliver a clear competitive edge in dexterity. They align with Musk’s view that high-volume manufacturing is one of the three critical elements missing from most other humanoid projects.
For Optimus to become the most capable humanoid robot, its hand needed to replicate the useful and applicable design of the human counterpart.
These filings demonstrate that Tesla has transformed years of engineering challenges into patented, elegant solutions — positioning the company strongly in the race toward general-purpose robotics.

Tesla intertwines FSD with in-house Insurance for attractive incentive
Every mile logged under FSD now carries a documented financial value—lower risk, lower cost—based on Tesla’s internal driving data rather than external crash statistics alone.
Tesla intertwined its Full Self-Driving (Supervised) suite with its in-house Insurance initiative in an effort to offer an attractive incentive to drivers.
Tesla announced that its new Safety Score 3.0 will automatically have a perfect score of 100 with every mile driven with Full Self-Driving (Supervised) enabled.
The change is designed to boost customers’ average safety scores and deliver noticeably lower monthly premiums.
The move marks the clearest link yet between Tesla’s autonomous driving technology and its proprietary insurance product. Tesla Insurance already relies on real-time vehicle data—such as acceleration, braking, following distance, and speed—to calculate a Safety Score between 0 and 100. Higher scores have long translated into cheaper rates.
Under the previous system, however, even brief manual interventions could drag down the average, frustrating owners who rely heavily on FSD. Version 3.0 eliminates that penalty for supervised autonomous miles, effectively treating FSD-driven segments as the safest possible driving behavior.
The incentive is immediate and financial. Drivers who keep FSD engaged for the majority of their trips will see their overall score rise, potentially shaving hundreds of dollars off annual premiums.
Tesla framed the update as a direct response to customer feedback, many of whom had complained that the old scoring model punished the very behavior it was meant to encourage.
For now, the program applies only to new policies in six states: Indiana, Tennessee, Texas, Arizona, Virginia, and Illinois.
Existing policyholders are not yet included, a point that drew swift questions from the Tesla community. Many owners in other states, including California and Georgia, expressed hope that the benefit would expand nationwide soon.
The announcement arrives as Tesla continues to roll out FSD Supervised updates and push for regulatory approval of more advanced autonomy. By tying insurance savings directly to FSD usage, the company is putting its own actuarial weight behind the technology’s safety claims.
Every mile logged under FSD now carries a documented financial value—lower risk, lower cost—based on Tesla’s internal driving data rather than external crash statistics alone.
Tesla has not disclosed exact premium reductions or the full rollout timeline beyond the six launch states.
Still, the message is clear: the more drivers trust FSD Supervised, the more Tesla Insurance will reward them. In an era when legacy insurers remain cautious about autonomous tech, Tesla is betting that its own data will prove the safest miles are the ones driven hands-free.
