I took a Tesla Model Y weekend-long Demo Drive – Here’s what I learned
I had a weekend with the new Tesla Model Y, and it truly solidified that EVs are the future, if we didn’t know that already.
Tesla offered me a weekend-long Demo Drive in the new Model Y, a new program the company is offering to people as a way to taste what it is like to own an EV. For me, it was a great look into owning an EV while renting a townhouse without charging infrastructure, but it gave me a lot more insight as well.
A Sales Advisor at a local showroom texted me several weeks back to see if I would want to take the new Model Y from the showroom to my house for a weekend. I immediately said yes, scheduled a weekend when family and friends would be nearby to experience things like Full Self-Driving, and booked it.
I picked it up on Saturday at 6 p.m. as the showroom closed, and I was on my way back home within ten minutes.
First Things First
My first order of business was getting some Full Self-Driving demos in, taking my Fiancè for a hands-free — but supervised — journey first. It was not her first time experiencing FSD, as we had taken a Demo Drive a few months back and experienced Hardware 3 and the past iteration of the Model Y.
However, we only used FSD for about ten minutes while checking out a Model Y to buy back in February.
The next morning, we picked my parents up for breakfast and took them on their first-ever FSD experience. They live in a rural part of my hometown in Southern Pennsylvania, where there are no lines on the road, potholes everywhere, deer constantly crossing the road, and sharp turns that can be dangerous during the daytime, as you cannot see oncoming headlights.
🚨 First order of business: Took my parents on an FSD journey.
“Wow!”
“This is crazy!”
You could hear the skepticism in my Dad’s voice as I started the drive. By the end of it, he couldn’t believe how it navigated non-lined backroads to his house! https://t.co/qisRxDlY5O

It was really something to see how my Dad changed his belief on FSD in the matter of just a few minutes. The night before, I took my Mom and Step Dad on a drive, and they felt the same way. My Dad is just more vocal about his skepticism, so I was happy to hear the reversal of his perspective.
Living without Charging and How It Changed My Mindset
One of the biggest things that kept me from buying the Model Y we looked at in February was the lack of charging in my neighborhood. I do not get to park directly in front of my front door, and my neighborhood is still considering some minor infrastructure for residents.
With the Long Range All-Wheel-Drive version of the new Model Y, Tesla boasts a range of 327 miles. We picked it up from the Showroom at 98 percent state-of-charge.
We ran our usual errands, went out to dinner, drove around for leisure to enjoy the car, and after all that, we still returned the car with 40 percent left. This truly eliminated any concerns I would have about charging at home, at least in the near term.
Realistically, I would like to have charging at home. The experience made me realize I would probably be driving to a Supercharger once a week to get range, which is about as frequent as I visit a gas pump now. It would not be a tremendous change, and it made me realize that when I do eventually make the jump, if I am still living in our townhome that we rent, I would get through it without any real issues.
Take my words as a bit of advice: If you’re overly concerned about not having charging at your apartment or home, don’t stress too much about it.
The Good and Bad with Full Self-Driving
Overall, our Full Self-Driving experience was incredibly valuable. My plan was to drive the car manually most of the time, but I truly only did that for roughly 5 percent of the miles we traveled together.
I planned for a big stress test on Sunday evening, and that’s what we did. We had to run out and get some things for a wedding we’re attending this coming weekend, and it required us to travel all over York from the East end to the West end, much of which was spent traveling on the Lincoln Highway. In West York, this stretch of highway is incredibly dysfunctional, busy, and is one of the drives I rue the most in the area.
Full Self-Driving made it very easy, as I just set the destination on several occasions and let the car do all the work.
Our first drive took us from our house to our local Target. It did everything flawlessly. I took over once we got into the parking lot just to find a parking space on my own:

I didn’t record the trip from Target to the Burlington Coat Factory, just a mile away, but I did record the next leg of the trip, which was from Burlington in East York to Burlington in West York. This was when I had my first complaint with FSD, and it dealt with the operation in parking lots.
You’ll see at the beginning of this video that there was an instance where the car waited for one cross-traffic warning to stop before proceeding, but ignored another cross-traffic warning from the other direction. The car pulled out on this person, you’ll see me wave to apologize, then I take control of the car, as it was too close to that other car for my liking. This was the only issue we experienced on this drive:
🚨 On this drive, FSD pulled out of this spot while there was a car approaching from our right (you’ll see the Red cross-traffic warning on the screen)
It also approached that vehicle a little too close for my liking, so to be safe I took over.
A great drive across town… pic.twitter.com/ANuZ4QcZB6

I found that parking lots were a weak point of FSD. It is not that I did not feel confident in its abilities to make it through these lots safely, but it reminded me a lot of what I think a 16-year-old who just got their license would drive through a busy parking area: hesitant, not confident, tentative.
Several of our X followers said the same thing:
This is such a problem… To the point I don’t even use start FSD from Park anymore

Parking lots are little bit of a weakness. But I believe this will be solved in the next update we get 💯

Leaving the West York Burlington and heading to a Walgreens to pick up some pictures we had printed was the next leg of our journey. This was where we got to test a difficult off-ramp on I-83 south and Autopark in the Walgreens parking lot.
The off-ramp for the Market Street exit and the on-ramp use the same lane, so merging traffic can be a bit of a nightmare for those trying to get off of the highway, which is what we were trying to do. FSD managed it cleanly, as several cars were merging onto I-83, the car found a soft spot in the traffic and got off without any issue. This impressed me because I know it can be stressful at times, especially during rush hour.
Autopark worked well and backed into a spot with no issues:
🚨 The final leg of our trip here: FSD did a great job of navigating through this parking lot and getting us onto a highway with a very short on-ramp (a very typical part of living and driving in Pennsylvania).
Also, Autopark did a great job! I would like to see it improve by… pic.twitter.com/OBefKZKDCo

Our final trip with FSD was from our home to the showroom. This would be our longest single-trip using FSD, and it was the most impressive yet.
The first thing it was tasked with was merging onto the highway with a very short lane to do so. FSD recognized this, saw an oncoming car that did not get over into the passing lane to make space (despite it having the room to do so as a courtesy), and sped up to take the slot it was given. It overtook slower cars, stayed in the right lane near on-ramps to make merging for others easier, and got us through the Harrisburg split with no issues.
As we turned onto the Carlisle Pike, the right lane was closed about a quarter-mile after we merged onto it. We had a vehicle beside us that did not want to let us over, so FSD waited, allowed the car to pass, and quickly took the three-car-length gap, safely getting on. This was a funny one because I noticed my Fiancè’s hand grab the handle on her door as a reactionary response.
She realized after it was unnecessary, and it did a better job than many people we know would have done:

This finished our experience with the Model Y for the weekend, and it was hard to say goodbye.
Conclusion
It seems that a trade-in will be happening in the coming months. My biggest reservation was residential charging, and I learned it really was not something I needed to be overly concerned about.
Full Self-Driving was truly the big thing that sold me on this car. The new Model Y is obviously a great vehicle to begin with, but FSD was the number one thing that I will miss because it made driving such a breeze.
More novelty things I will miss are being able to watch YouTube while I wait in the car, and pranking people with the Fart on Contact/Sit Happens feature, something that gave us all a good laugh.
It was a great weekend with the new Model Y! In the coming months, I hope to get my hands on another vehicle for a weekend.

Tesla is sending its humanoid Optimus robot to the Boston Marathon
Tesla’s Optimus robot is heading to the Boston Marathon finish line
Tesla’s Optimus humanoid robot will be stationed at the Tesla showroom at 888 Boylston Street in Boston, right along the final stretch of the Boston Marathon today, ready to cheer on runners and pose for photos with spectators.
According to a Tesla email shared by content creator Sawyer Merritt on X, Optimus will be at the Boston Boylston Street showroom on April 20, coinciding with Marathon Monday weekend. The Boston Marathon finishes on Boylston Street, and the surrounding area draws hundreds of thousands of spectators along with international broadcast coverage. Placing Optimus there puts it in front of a massive public audience at zero advertising cost.
Just got this email. @Tesla’s Optimus robot is coming to Boston.

The Tesla showroom is at 888 Boylston Street, between Gloucester Street and Fairfield Street. The final mile of the marathon runs directly along Boylston Street, with runners passing the big stores before reaching the finish line at Copley Square.
Optimus was first announced at Tesla’s AI Day event on August 19, 2021, when Elon Musk presented a vision for a general-purpose robot designed to take on dangerous, repetitive, and unwanted tasks. In March 2026, Optimus appeared at the Appliance and Electronics World Expo in Shanghai, where on-site staff stated that mass production of the robot could begin by the end of 2026. Before that, it showed up at the Tesla Hollywood Diner opening in July 2025 and at a Miami showroom event in December 2025.
Tesla’s well-calculated display of Optimus gives the public a low-pressure first encounter with a robot that Tesla is preparing to soon deploy at scale. The company has previously indicated plans to manufacture Optimus robots at its Fremont facility at up to 1 million units annually, with an Optimus production line at Gigafactory Texas targeting 10 million units per year.

Musk has said that Optimus “has the potential to be more significant than the vehicle business over time,” and separately that roughly 80 percent of Tesla’s future value will come from the robot program. Whether that holds depends on production execution. For now, Boston gets a preview of what that future looks like, standing at the finish line on Boylston Street while 32,000 runners pass by.

Tesla’s golden era is no longer a tagline
Tesla “golden era” teaser video highlights the future of transportation and why car ownership itself may be the next thing to change.
The golden age of autonomous ridesharing is arriving, and Tesla is making sure we can all picture a future that looks like the future. A recent teaser posted to X shows a Cybercab parked outside a home, and with a clear message that your everyday life may soon look like this when the driverless vehicles shows up at your door.
Tesla has begun the rollout of its Robotaxi service across US cities, and the production of its dedicated, fully-autonomous Cybercab vehicle. The first Cybercab rolled off the Giga Texas assembly line on February 17, 2026, with volume production now targeted for this month. Additionally, the Robotaxi service built around it is already running, without human drivers, in US cities.
Tesla Cybercab production ignites with 60 units spotted at Giga Texas
The Cybercab is built without a steering wheel, pedals, or side mirrors, designed from the ground up for unsupervised autonomous operation. Musk described the manufacturing approach as closer to consumer electronics than traditional car production, targeting a cycle time of one unit every ten seconds at full scale.
Drone footage from April 13, 2026 captured over 50 Cybercab units on the Giga Texas campus, with several clustered near the crash testing facility. Musk has noted that Tesla plans to sell the Cybercab to consumers for under $30,000, and owners will be able to add their vehicles to the Tesla robotaxi network when not in personal use, potentially generating income to offset the vehicle’s purchase cost. That model changes the math on vehicle ownership in a meaningful way, making a car something closer to a depreciating asset that can also earn by paying itself off and generate a profit.
During Tesla’s Q4 earnings call, the company confirmed plans to expand the Robotaxi program to seven new cities in the first half of 2026, including Dallas, Houston, Phoenix, Miami, Orlando, Tampa, and Las Vegas. The service already runs without safety drivers in Austin, and public road testing of the Cybercab has expanded to five states, including California, Texas, New York, Illinois, and Massachusetts.

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
— SETI Park (@seti_park) April 16, 2026
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.
