Back when the Model 3 was unveiled, Tesla immediately attracted a good amount of criticism over the vehicle’s design. Arguments against the all-electric sedan were many, with arguments being presented against its utilization of a single 15” center display and its hyper-minimalistic interior. The vehicle’s glovebox, which could only be opened through the touchscreen, also attracted its own fair share of eyebrows.
‘Crazy’ and ‘Impractical’ Ideas
To a good number of car enthusiasts, the idea of a glovebox that can’t even be opened manually was insane. Practically all vehicles in the market, from affordable econoboxes from Japan to luxury cars from Germany employ a manual latch for the glovebox, after all. It was something that was so simple, so traditional, and here Tesla was stubbornly refusing to follow along.
It would be pretty easy to put a manual latch on the glovebox, so Tesla’s insistence on an electronically-operated mechanism seemed almost like hubris on the EV maker’s part. Tesla did roll out changes to the Model 3’s glovebox, such as a feature that automatically opens the storage area in the event of a crash. This was rolled out following an incident where a Model 3 was involved in an accident that shattered the 15” display, giving the driver a very difficult time accessing the vehicle’s title and insurance papers.
Over the years, Tesla has added numerous features to the Model 3. These include Sentry Mode, which actively monitors a vehicle’s surroundings, and TeslaCam, which acts as a built-in dashcam for the all-electric sedan on the road. The videos were saved on a flash drive that drivers would need to insert into the front USB port of the Model 3. The feature is incredibly useful, though it requires some work on the part of Tesla’s customers. This was perhaps the reason why the use of features like Sentry Mode and TeslCam are not universally used by drivers. This may change soon with the introduction of the 2021 Model 3.
Pieces of a Puzzle
For the Model 3 “refresh,” Tesla introduced a number of key updates, from a new center console and new Aero Wheels to new headlights. Minor updates were also introduced, such as a USB port inside the glovebox. A video from Hong Kong featuring a 2021 Model 3 further revealed that the USB port inside the glovebox already has a 64 GB flash disk in it. This incredibly minor change, which almost feels like an afterthought considering the Model 3’s major updates, makes features like Sentry Mode and TeslaCam much easier to use.
This makes the Model 3 more secure as well, as even thieves that are familiar with Teslas will no longer have any way to access the flash drive that contains the vehicle’s video recordings. Prior to the “refresh,” thieves could simply rip out the flash drive that holds Sentry Mode’s recordings, which is quite unlikely but still plausible. This will no longer be true with the 2021 Model 3, especially as Tesla has already added an extra layer of security in the form of “Glovebox PIN,” which was previously released through an over-the-air software update.
What is quite remarkable is that these improvements would not work as well as they do now if Tesla had included a manual latch for the Model 3’s glovebox. It was difficult to see the point behind Tesla’s stubborn refusal to include something as simple as a physical glovebox latch during the vehicle’s initial launch and release, but it appears that the feature, or lack thereof, was something that would be useful years into the vehicle’s release.
The Long Game
This is something that has become much of a theme in the Tesla story. The company or its CEO does something, and critics pounce on the opportunity to squeeze in a few shots. Products are rolled out and improved through over-the-air updates, and before the dust settles, Tesla and Elon Musk’s once-controversial strategies end up making sense. This was the case with the Model 3’s glovebox, and it would likely be true for other controversial aspects of Tesla’s vehicles as well, such as the Cybertruck’s design and novel features.
Ultimately, this tendency could very well be explained by the fact that Tesla simply looks farther ahead than any of its critics. Tesla skeptics may focus on what the company is doing now, or the state of its products today, but Elon Musk and his team are always looking into the future. This may very well be the reason why even Wall Street analysts seem to have a difficulty understanding Tesla’s business. Just recently, for example, Morgan Stanley upgraded TSLA stock to an “Overweight” rating. According to the financial firm, this is due to Tesla’s business expanding from carmaking to other segments such as software. This is something that longtime TSLA bulls have been highlighting for years.
What is rather interesting is that Tesla may continue to confound skeptics for years to come. Just like the Model 3’s glovebox, the company is still rolling out strategies and products that don’t make sense for skeptics, such as the FSD beta and features like Smart Summon. A look at Autopilot’s subpar scores in tests from organizations such as Consumer Reports highlight this point. Yet just like the humble Model 3 glovebox, perhaps features like Summon could serve a higher purpose years down the road.

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.
