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.
SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.
Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.
This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:
🚀 Elon says Raptor 4 will make 300 tons of thrust at sea level at roughly the same mass as Raptor 3.
How far Raptor has come:
Raptor 1: 185 tf, 2,080 kg
Raptor 2: 230 tf, 1,630 kg
Raptor 3: 250 tf, 1,525 kg
Raptor 4: 300 tf33 on Super Heavy = ~9,900 tf, nearly 3x Saturn V https://t.co/HQDswZhyvL
— TESLARATI (@Teslarati) October 26, 2026
With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.
This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.
Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.
Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.
The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.
Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.
For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.
Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.

Tesla shows what Roadster drivers will see on screen before thruster activation
Tesla’s Roadster video reveals a fighter jet inspired cockpit with a 5,500 PSI thruster gauge.
Tesla has given future owners their clearest look yet at the cockpit of its next generation Roadster. In a 34 second video posted to X on Friday afternoon, the company walked through the car’s touchscreen with a caption: “Inspired by fighter jet cockpits, Roadster’s interface was designed around the pilot.”
The clip opens on a black screen with red graphics and a 3D wireframe of the car, which sits beside the Roadster’s squared off yoke. Tapping parts of the model brings up controls for the rear wing, including low drag and high downforce positions, along with a charging page with a charge limit bar and a small music player. A row of tabs along the bottom reads Home, Vehicle, Listen, Climate and Navigate.
Most of the video is spent in Track Mode. The dashboard shows a live circuit map, a list of session lap times, brake and motor temperatures, and pressure and temperature readouts for each tire. A setup page lets the driver pick Auto, Low Drag, High Downforce or Custom aero modes, adjust aero balance and brake balance, and switch stability and traction control off. Along the bottom, a status bar reads “Thruster · 5,500 PSI” next to a “Boost Ready” indicator.
That gauge ties the software to the hardware Tesla showed off near Waco, Texas on October 15. The Thrust and Rocket versions use cold gas thrusters fed by carbon overwrapped pressure vessels, and Tesla lists 0 to 60 mph times of under 0.9 seconds and under 0.59 seconds for them, as Teslarati detailed in its breakdown of the three Roadster configurations. The base Performance car relies on a fan and ground sealing system for grip, and the aero settings on screen match the active wings and suction setup covered in our look at how the Roadster generates downforce.
The Roadster layout is a departure from the rest of Tesla’s lineup. Instead of a map centered screen, the Roadster puts the car itself at the center of the home page, and Tesla’s Roadster page lists two smaller forward displays alongside the main touchscreen. Tesla has not said whether any of the Track Mode telemetry will make its way to the Model 3 Performance or other vehicles.
The interface could still change before deliveries. Elon Musk said at the event that Roadster production will begin in 2028, and Tesla says the flagship Rocket version is not approved for public road use. Reservations are open with a $50,000 payment, while Thrust is listed as a limited release and Rocket is invite only.
Those who want to see the car in person will get their first chance this weekend. The Roadster goes on display in the lobby of the Petersen Automotive Museum in Los Angeles from October 24 to 27, according to Sawyer Merritt, the first time the public will be able to view it up close.

Tesla reveals Optimus Academy, where robots teach themselves
Tesla has begun building production quality Optimus robots in Fremont and revealed its training plan.
Tesla has started building Optimus on the high volume line it set up inside its Fremont factory, and the company says the robots coming off it are the first that meet the bar for a real product. “The bots coming off this line are the first production-quality bots that we have manufactured,” Tesla wrote in its third quarter shareholder letter, adding that it has “proven that the current manufacturing process for Optimus is suitable for a commercial product.”
The line sits in space that built the Model S and Model X until this spring. Tesla cleared the old vehicle line in 46 days, as Teslarati reported in July, to make room for robot production sized for one million units a year. On Wednesday’s earnings call, Elon Musk said most of the equipment for that capacity is already in Fremont, with output set to climb toward roughly 20,000 robots a week as the line ramps.
Musk described the ramp as a classic S curve. “The growth of Optimus is an S curve, but the initial curve is a shallow slope,” he said. The team is now refining the robot’s AI, electromechanical design, reliability and service life, and Musk expects that work to be finished by the end of next year, when Tesla plans to start delivering Optimus to outside companies for dangerous, repetitive and around the clock jobs.
The most interesting part of the call was how Tesla plans to teach the robots. Its cars send real driving data back to the AI team from millions of vehicles, but Optimus has no fleet like that yet. “A big difference with Optimus versus the cars is we don’t have this vast fleet of cars from which we can gather training data,” Musk said. Tesla’s answer is an Optimus Academy, where 10,000 to 20,000 robots will practice a wide range of tasks and feed what they learn into the next version of the model. Every unit off the Fremont line becomes a source of that training data.
Smarter hardware is on the way too. Tesla plans to put its AI5 chip into Optimus next year, and Musk said a new Optimus video should arrive within one or two months showing the robot completing tasks driven by AI rather than preprogrammed motions. He took aim at rival humanoid demos that only run scripted routines, saying those would not hold up in the real world.
The supply chain is lining up behind the program. In September, Tesla certified Tuopu, Joyson and Sanhua as mass production partners for Optimus components. A far larger Optimus factory is also rising at Giga Texas, where drone footage from Joe Tegtmeyer showed the steel frame nearing completion, and Musk has pegged that plant’s long term target at 10 million robots a year.
Tesla executives also said Optimus production costs are trending toward the expected manufacturing cost of Cybercab, a sign the robot is being engineered for volume from the start. The hands remain the toughest piece of the design, a point Musk also made at the X Takeover event earlier this month, as Teslarati covered at the time, and that is where much of the current engineering effort is focused.
