Fostering a more harmonious world.

[David Havasi @daveydo2000]

Ummm… we need to talk about Tesla’s latest Full Self-Driving software version 12.3.3. Last night FSD v12.3.3 was downloaded to my Tesla Model 3 via an over-the-air update while it sat parked in my garage.

This morning my car drove me from my house, to lunch, then to the gym, then back to my house. MY CAR DROVE ME. The only time I had to disengage FSD was when pulling into my neighborhood, my car smoothly came to a stop to let a woman cross the street who was walking her dogs but she stopped too and waived me through so I disengage FSD and made the turn myself so she could carry on with her walk.

THEN this afternoon my Tesla drove me, door-to door, over 230 miles across the state of Florida to Miami. I repeat: MY. CAR. DROVE. ME. TO. MIAMI. The only time I disengaged FSD was when going through a toll section on I-75 because I wasn’t quite sure what it would do so I just took over. Beside that IT DROVE ME, even through downtown Miami during rush-hour. It was smooth, confident, and drama free.

To be honest, FSD (beta) software v11, and previous versions, were quite rough/glitchy in my experience; but since Tesla has switched to end-to-end neural network training with FSD v12… IT IS NEXT LEVEL. It’s a quantum leap. I can’t believe what I am experiencing. I want to shout it from the roof tops. The drives today were not only stress-free, they were incredibly relaxing. I actually felt safer with FSD on than with me driving on my own, which is the first time I have ever felt that way using FSD. v12 has changed evening.

My mind is blown. This technology is going to change/save lives! I am thrilled that we have gotten this far. The over-the-air updates are coming more and more frequently, so it’s going to continue to get even better from here; eventually getting to a level that is many times smoother and safer than a human driver could ever possibly be.

What is really astonishing is that this is not some crazy closed off technology on some rare experimental prototype vehicle. Anyone can experience what I experienced. EVERY NEW TESLA IS CAPABLE OF THIS*. A car that YOU can get TODAY can do this. That’s amazing!

After experiencing what I’ve experienced today there is no question in my mind that open-world fully-autonomous vehicles are possible; and it is coming much sooner (in a Tesla near you) than most people realize.

Yes, but that BYD (Denis) is a large luxury vehicle that weighs over 6000 pounds, and that 600+ miles figure is based on the CLTC rating system, which is unrealistically generous. The equivalent EPA rated range for that vehicle would just be in the mid 400s.,The Roadster would need around a 200 kWh pack to achieve over 600 miles of range EPA rated range. With current energy density that would make the pack way too heavy to be put in a lightweight hyper sports car.

@klara_sjo Oof. Daddy didn’t hug enough.

Model Y was the best selling vehicle of any kind in Australia for the month of May

Making it the first electric car in history to lead the overall AU sales charts across all fuel types

Running high grade + heavy load feels effortless in the Tesla Semi. Enough power to maintain speed when climbing, and regenerative braking making descents save and controllable. All while in silence.

[Sawyer Merritt @SawyerMerritt]

The @Tesla Model Y was the #1 best-selling vehicle overall in South Korea in May.

By brand, Tesla recorded the highest number of imported registrations at 10,866 units:
• Model Y Premium: 7,195 units
• Model Y L Premium: 1,513 units

This was followed by BMW with 6,555 units, Mercedes with 3,553 units, Audi with 1,509 units, Lexus with 1,291 units, Volvo with 1,058 units, and BYD with 1,032 units.

@JordanKeto Those people are thinking the same thing about you. It’s interesting how that works.

[Sawyer Merritt @SawyerMerritt]

Covenant Logistics has completed two weeks of @Tesla Semi testing. They were blown away by its capabilities.

"We were amazed at the performance of the Tesla Semi and felt a level of confidence that was hard to match in a diesel truck.

As one of our final runs we tackled a section of I-5 between Santa Clarita and the San Joaquin Valley over the Tejon Pass - famously known as "The Grapevine" - a lane critical to trucks hauling cargo from the ports in Oakland, Los Angeles, and Long Beach. "The Grapevine" sits at an elevation of 4,160 feet and represents the highest point on I-5 in California. The northbound descent from Tejon Summit drops 2,613 feet over 11.6 miles, with the steepest section — known as the Grapevine Hill — running about 6% grade for 5 miles.

Running the Grapevine with a loaded trailer is about as demanding a real-world test as you could design for any truck. Running Northbound - lose momentum on a steep grade with a heavy load can be stressful as speed drops fast and recovering on that grade is challenging. Running Southbound requires attention to braking and heat management (which isn't a problem for an EV when you've got regenerative braking doing most of the work)."

Imagine if your car could drive you to The Grove and find parking with just one tap.

Every new Tesla (even the cheapest base model) can do this today.

FSD is absolutely jaw-dropping.

You’ve never seen anything like this.

It reversed for a full 7 minutes… right on the edge of a cliff.

Robert Marks on @Tesla FSD (Supervised) after buying a Model Y:

"Its self-driving is the most impressively engineered consumer product since the smartphone. I say this as a practicing electrical and computer engineering professor with decades of experience in algorithms and artificial intelligence.

Among others, I’ve showed off my Tesla to a control theory professor, a retired Marine fighter pilot, and a retired police officer. All were agog.

Whether Tesla ultimately dominates the future of transportation or merely helps ignite it, one thing is clear: the automobile is being reinvented before our eyes. For those like me who grew up thinking of cars as engines, gears, and gas tanks, stepping into a Tesla feels less like buying a new car and more like getting a glimpse of tomorrow."

Pretty good progress

[David Havasi @daveydo2000]

@wholemars @Everman This is the vehicle that me and legions of others have been screaming at Tesla to build for years now.

I've been driving a @Tesla for the past 2 days and I don't think I can ever go back to any other car

🚨BREAKING:
Tesla has been authorized by the State of Texas to operate driverless vehicles commercially under the new law that took effect today, May 28th, 2026. Tesla has officially self-certified the software running on its robotaxis as Level 4. $TSLA

Everyone should experience this.

An electric car driving you around.

I honestly feel bad when I see all these drivers pay $4.50 per gallon for gas while also needing to manually drive the car.

It’s highway robbery. Literally.

@Jason Well, that and the r*ping… and the stonewalling of the Epstein files to protect p*dos… and the whole trying-to-upend-the-democratic-process thing January 6th…

Been using Grok Build these past few days, and the thing that really got me hooked is Imagine and Imagine Video.

I built a full dinosaur encyclopedia site — every image, every video clip on it, all generated by Grok itself. One prompt: "build a dinosaur encyclopedia site, generate matching images and videos, add them in" — visuals, video, copy, layout, the whole thing done in one flow. No jumping between a dozen tools.

It's perfect for building science and education sites for kids — dinosaurs, space, animals, history, geography… Grok generates vivid visuals and videos that make knowledge way easier to grasp, more visual, more fun.
