Tesla’s ‘Big Green’ Semi truck gets a shoutout from Kimbal Musk
The Tesla Semi recently got a shoutout from someone who is part of Elon Musk’s most intimate circle — Kimbal Musk. In a recent post on his Instagram page, Kimbal dubbed the electric long-hauler as a “Big Green” Tesla Semi, referencing his nonprofit organization aimed at building Learning Gardens for schools across the United States.
Quite interestingly, Kimbal Musk’s projects, such as Big Green and Square Roots, could benefit from using the Tesla Semi. Big Green, for one, is involved with building interactive, modular gardens where young American students can learn about real food and healthy eating habits. Considering Kimbal Musk’s goal of building 100,000 Learning Gardens across the US, having an electric truck that can haul materials would be a good idea.
The Tesla Semi is also a perfect match for Kimbal’s Square Roots farming project. Square Roots involves converting old shipping crates into advanced, climate-controlled indoor farms that can yield more than 50 pounds of organic, non-GMO, pesticide-free greens each week. So far, Square Roots is only operating its shipping container-farms in Brooklyn, NY, but it’s not too difficult to see a future where the farming startup’s indoor farms can be transported and set up in other key US cities.

Since being unveiled last November, the Tesla Semi has been sighted numerous times across the United States. Back in March, Elon Musk announced in his social media pages that Tesla would start using the all-electric trucks as transport vehicles to haul battery packs from Gigafactory 1 in Sparks, NV to the Fremont factory in CA. The two Tesla Semi prototypes have also been spotted conducting transport runs between Tesla’s headquarters in Palo Alto, CA and Fremont.
During its unveiling back in November, Elon Musk outlined several of the Semi’s impressive specs. Just like Tesla’s other vehicles, the Semi is capable of quick acceleration, thanks to its four Model 3-derived electric motors that produce instant torque. From a dead stop, the Semi is capable of sprinting from 0-60 mph in just 5 seconds, compared to about 15 seconds on a similar Class 8 diesel truck. With a full 80,000-pound load, the Semi can hit 60 mph in 20 seconds. On average, diesel-powered Class 8 trailers hit highway speeds in about a minute.
The Tesla Semi is capable of climbing 5% grades at a steady 65 mph, unlike diesel trucks that max out at 45 mph on 5% grades. Lastly, thanks to an upcoming network of Megachargers, the Semi will be capable of charging up to 400 miles of range in just 30 minutes.

During Tesla’s Q1 2018 earnings call, both Elon Musk and CTO JB Straubel noted that the production version of the Semi’s long-range variant would likely have almost 600 miles of range per charge. These statements, of course, stand in stark contrast to criticisms from Tesla’s competitors, especially Daimler AG head of trucks Martin Daum, who threw shade at Tesla earlier this year by suggesting that the Semi’s rated specs, if accurate, defy the laws of physics. According to Straubel, much of competitors’ criticisms come from a misunderstanding of Tesla’s battery technology.
“There’s a fundamental misunderstanding, I think, of what the current technology in our existing products can actually do. Maybe that’s just a misunderstanding of the current status of the technology versus others in the industry. If they’re benchmarking sort of the best battery pack they can buy from a supplier, and then mapping that with what the Semi could do, it doesn’t solve,” Straubel said.
While Tesla is not actively pushing sales for the Semi, Straubel noted during the first-quarter earnings call that the all-electric long-hauler has roughly 2,000 reservations to date. Production of the Tesla Semi is expected to begin in 2019.
Tesla CEO Elon Musk teased the insane capabilities of the next major Full Self-Driving update just hours after the company rolled out version 14.2 to owners.
Tesla Full Self-Driving v14.2 had some major improvements from the previous iteration of v14.1.x. We were on v14.1.7, the most advanced configuration of the v14.1 family, before Tesla transitioned us and others to v14.2.
However, Musk has said that the improvements coming in the next major update, which will be v14.3, will be where “the last big piece of the puzzle finally lands.”
14.3 is where the last big piece of the puzzle finally lands
— Elon Musk (@elonmusk) November 21, 2025
There were some major improvements with v14.2, most notably, Tesla seemed to narrow in on the triggers that caused issues with hesitation and brake stabbing in v14.1.x.
One of the most discussed issues with the past rollout was that of brake stabbing, where the vehicle would contemplate proceeding with a route as traffic was coming from other directions.
We experienced it most frequently at intersections, especially four-way stop signs.
Elon Musk hints at when Tesla can fix this FSD complaint with v14
In our review of it yesterday, it was evident that this issue had been resolved, at least to the extent that we had no issues with it in a 62-minute drive, which you can watch here.
Some owners also reported a more relaxed driver monitoring system, which is something Tesla said it was working on as it hopes to allow drivers to text during operation in the coming months. We did not test this, as laws in Pennsylvania prohibit the use of phones at any time due to the new Paul Miller’s Law, which took effect earlier this year.
However, the improvements indicate that Tesla is certainly headed toward a much more sentient FSD experience, so much so that Musk’s language seems to be more indicative of a more relaxed experience in terms of overall supervision from the driver, especially with v14.3.
Musk did not release or discuss a definitive timeline for the release of v14.3, especially as v14.2 just rolled out to Early Access Program (EAP) members yesterday. However, v14.1 rolled out to Tesla owners just a few weeks ago in late 2025. There is the potential that v14.3 could be part of the coming Holiday Update, or potentially in a release of its own before the New Year.
Tesla rolled out Full Self-Driving version 14.2 yesterday to members of the Early Access Program (EAP). Expectations were high, and Tesla surely delivered.
With the rollout of Tesla FSD v14.2, there were major benchmarks for improvement from the v14.1 suite, which spanned across seven improvements. Our final experience with v14.1 was with v14.1.7, and to be honest, things were good, but it felt like there were a handful of regressions from previous iterations.
While there were improvements in brake stabbing and hesitation, we did experience a few small interventions related to navigation and just overall performance. It was nothing major; there were no critical takeovers that required any major publicity, as they were more or less subjective things that I was not particularly comfortable with. Other drivers might have been more relaxed.
With v14.2 hitting our cars yesterday, there were a handful of things we truly noticed in terms of improvement, most notably the lack of brake stabbing and hesitation, a major complaint with v14.1.x.
However, in a 62-minute drive that was fully recorded, there were a lot of positives, and only one true complaint, which was something we haven’t had issues with in the past.
The Good
Lack of Brake Stabbing and Hesitation
Perhaps the most notable and publicized issue with v14.1.x was the presence of brake stabbing and hesitation. Arriving at intersections was particularly nerve-racking on the previous version simply because of this. At four-way stops, the car would not be assertive enough to take its turn, especially when other vehicles at the same intersection would inch forward or start to move.
This was a major problem.
However, there were no instances of this yesterday on our lengthy drive. It was much more assertive when arriving at these types of scenarios, but was also more patient when FSD knew it was not the car’s turn to proceed.
Can report on v14.2 today there were ZERO instances of break stabbing or hesitation at intersections today
It was a significant improvement from v14.1.x

This improvement was the most noticeable throughout the drive, along with fixes in overall smoothness.
Speed Profiles Seem to Be More Reasonable
There were a handful of FSD v14 users who felt as if the loss of a Max Speed setting was a negative. However, these complaints will, in our opinion, begin to subside, especially as things have seemed to be refined quite nicely with v14.2.
Freeway driving is where this is especially noticeable. If it’s traveling too slow, just switch to a faster profile. If it’s too fast, switch to a slower profile. However, the speeds seem to be much more defined with each Speed Profile, which is something that I really find to be a huge advantage. Previously, you could tell the difference in speeds, but not in driving styles. At times, Standard felt a lot like Hurry. Now, you can clearly tell the difference between the two.
It seems as if Tesla made a goal that drivers should be able to tell which Speed Profile is active if it was not shown on the screen. With v14.1.x, this was not necessarily something that could be done. With v14.2, if someone tested me on which Speed Profile was being used, I’m fairly certain I could pick each one.
Better Overall Operation
I felt, at times, especially with v14.1.7, there were some jerky movements. Nothing that was super alarming, but there were times when things just felt a little more finicky than others.
v14.2 feels much smoother overall, with really great decision-making, lane changes that feel second nature, and a great speed of travel. It was a very comfortable ride.
The Bad
Parking
It feels as if there was a slight regression in parking quality, as both times v14.2 pulled into parking spots, I would have felt compelled to adjust manually if I were staying at my destinations. For the sake of testing, at my first destination, I arrived, allowed the car to park, and then left. At the tail-end of testing, I walked inside the store that FSD v14.2 drove me to, so I had to adjust the parking manually.
This was pretty disappointing. Apart from parking at Superchargers, which is always flawless, parking performance is something that needs some attention. The release notes for v14.2. state that parking spot selection and parking quality will improve with future versions.

However, this was truly my only complaint about v14.2.

SpaceX issues statement on Starship V3 Booster 18 anomaly
The incident unfolded during gas-system pressure testing at the company’s Massey facility in Starbase, Texas.
SpaceX has issued an initial statement about Starship Booster 18’s anomaly early Friday. The incident unfolded during gas-system pressure testing at the company’s Massey facility in Starbase, Texas.
SpaceX’s initial comment
As per SpaceX in a post on its official account on social media platform X, Booster 18 was undergoing gas system pressure tests when the anomaly happened. Despite the nature of the incident, the company emphasized that no propellant was loaded, no engines were installed, and personnel were kept at a safe distance from the booster, resulting in zero injuries.
“Booster 18 suffered an anomaly during gas system pressure testing that we were conducting in advance of structural proof testing. No propellant was on the vehicle, and engines were not yet installed. The teams need time to investigate before we are confident of the cause. No one was injured as we maintain a safe distance for personnel during this type of testing. The site remains clear and we are working plans to safely reenter the site,” SpaceX wrote in its post on X.
Incident and aftermath
Livestream footage from LabPadre showed Booster 18’s lower half crumpling around the liquid oxygen tank area at approximately 4:04 a.m. CT. Subsequent images posted by on-site observers revealed extensive deformation across the booster’s lower structure. Needless to say, spaceflight observers have noted that Booster 18 would likely be a complete loss due to its anomaly.
Booster 18 had rolled out only a day earlier and was one of the first vehicles in the Starship V3 program. The V3 series incorporates structural reinforcements and reliability upgrades intended to prepare Starship for rapid-reuse testing and eventual tower-catch operations. Elon Musk has been optimistic about Starship V3, previously noting on X that the spacecraft might be able to complete initial missions to Mars.
