The Tesla Semi will shake the trucking industry to its roots
Elon Musk’s new Master Plan calls for an expansion of its vehicles into other categories, including buses and heavy duty trucks, both of which will unveiled in about a year. Undoubtedly, carbon emissions worldwide would fall precipitously if the general automobile consumer transitioned to a tailpipe-free electric Tesla, but that’s not what Elon Musk is after. His goal is a full frontal assault on carbon emissions of all kinds including a Tesla Semi. His objective is for nothing less than a world that no longer uses fossil fuels to power its transportation system, even on a commercial scale.
Looking back at the Volkswagen diesel scandal and why it was significant, beyond morality, diesel engines especially heavy-duty diesel trucks spew emissions on another level. To make the problem worse, passenger cars normally have a useful life of around 200,000 miles. Diesel powered tractors can be on the road for a decade or more, spewing out toxins for millions of miles before they are replaced. The pollution control systems on older trucks are rudimentary at best.
In Southern California, the pollution from drayage trucks that haul shipping containers from ports to inland distribution centers is so bad, it has sparked a number of plans to replace them with electric versions. One solution proposed by Siemens calls for equipping trucks with pantographs so they can draw electricity from overhead wires along their routes.
Former Tesla executive Ian Wright sold his stock in Tesla Motors when Elon Musk came on board. Wright wanted to attack the challenges of truck pollution rather than build some silly sports car. He has since created his own company called Wrightspeed that focuses on cleaning up the emissions from heavy duty garbage trucks. He has invented a new form of hybrid powertrain that uses a small gas turbine to recharge the batteries. The turbine is so clean, it doesn’t even need a catalytic converter to meet California’s stringent emissions rules.
The problem with electric trucks today is that the batteries need to be so large and heavy they would take up much of the space available for hauling freight. Not only that, they would be prohibitively expensive. The Wrightspeed system is a compromise that attempts to strike a balance between cost and range. It has attracted international attention and the company has recently signed a contract to re-power a fleet of diesel buses in New Zealand.
-->The allure of electric trucks has created an opportunity for hucksters and charlatans. Earlier this year, a Florida company calling itself Oakridge Global Energy Solutions said it had developed a battery for Freedom Trucking of Minneapolis that would haul an 80,000 lb. load 400 miles. That claim turned out to be vaporware.
Another entrant into the heavy truck sweepstakes is a company calling itself Nikola Motors — a rather obvious attempt to somehow conflate what it is doing with the work of Tesla Motors. It says its Nikola One tractor will have 2,000 horsepower. 3,700 lb-ft of torque, a 325 kWh battery, 6 wheel drive with torque vectoring and 1,200 miles of range. It relies on an onboard natural gas turbine to keep the battery charged while driving.
The design concept for the Nikola One is visually appealing and the company says it has 7,000 pre-orders for the truck worth a total of $2.3 billion. Of course, it currently has no factory, no battery factory, and little corporate infrastructure other than its website.
We can assume the Tesla Semi will not have a range extender engine of any type. How Tesla will make an electric tractor that can haul heavy loads long distances that is cost competitive remains unclear. But if Elon says that’s what Tesla will do, we can be pretty sure it will — eventually.
JB Straubel says he and Elon talked about electric airplanes long before they decided to build automobiles. And ocean going cargo vessels are some of the worst polluters on the face of the planet. Musk probably has a plan for them, too. Look for those ideas to be part of Master Plan Numero Tres.

Elon Musk gives nod to SpaceX’s massive, previously impossible feat
It was the booster’s 30th flight, a scenario that seemed impossible before SpaceX became a dominant force in spaceflight.
Elon Musk gave a nod to one of SpaceX’s most underrated feats today. Following the successful launch of the Transporter-15 mission, SpaceX seamlessly landed another Falcon 9 booster on a droneship in the middle of the ocean.
It was the booster’s 30th flight, a scenario that seemed impossible before SpaceX became a dominant force in spaceflight.
Elon Musk celebrates a veteran Falcon 9 booster’s feat
SpaceX completed another major milestone for its Smallsat Rideshare program on Friday, successfully launching and deploying 140 spacecraft aboard a Falcon 9 from Vandenberg Space Force Base. The mission, known as Transporter-15, lifted off two days later than planned after a scrub attributed to a ground systems issue, according to SpaceFlight Now. SpaceX confirmed that all payloads designed to separate from the rocket were deployed as planned.
The Falcon 9 used for this flight was booster B1071, one of SpaceX’s most heavily flown rockets. With its 30th mission completed, it becomes the second booster in SpaceX’s fleet to reach that milestone. B1071’s manifest includes five National Reconnaissance Office missions, NASA’s SWOT satellite, and several previous rideshare deployments, among others. Elon Musk celebrated the milestone on X, writing “30 flights of the same rocket!” in his post.
Skeptics once dismissed reusability as unfeasible
While rocket landings are routine for SpaceX today, that was not always the case. Industry veterans previously questioned whether reusable rockets could ever achieve meaningful cost savings or operational reliability, often citing the Space Shuttle’s partial reusability as evidence of failure.
-->In 2016, Orbital ATK’s Ben Goldberg argued during a panel that even if rockets could be reusable, they do not make a lot of sense. He took issue with Elon Musk’s claims at the time, Ars Technica reported, particularly when the SpaceX founder stated that fuel costs account for just a fraction of launch costs.
Goldberg noted that at most, studies showed only a 30% cost reduction for low-Earth orbit missions by using a reusable rocket. “You’re not going to get 100-fold. These numbers aren’t going to change by an order of magnitude. They’re just not. That’s the state of where we are today,” he said.
Former NASA official Dan Dumbacher, who oversaw the Space Launch System, expressed similar doubts in 2014, implying that if NASA couldn’t make full reusability viable, private firms like SpaceX faced steep odds.

Tesla AI and Autopilot VP hints that Robovan will have RV conversions
Tesla’s vice president of AI and Autopilot software, Ashok Elluswamy, hinted at the linitiative in a reply to Y Combinator CEO Garry Tan.
It appears that Tesla is indeed considering an RV in its future pipeline, though the vehicle that would be converted for the purpose would be quite interesting. This is, at least, as per recent comments by a Tesla executive on social media platform X.
Robovan as an RV
Tesla’s vice president of AI and Autopilot software, Ashok Elluswamy, hinted at the linitiative in a reply to Y Combinator CEO Garry Tan, who called for a startup to build RVs with Full Self-Driving capabilities. In his reply, Elluswamy simply stated “On it,” while including a photo of Tesla’s autonomous 20-seat people mover.
Tesla unveiled the Robovan in October 2024 at the “We, Robot” event. The vehicle lacks a steering wheel and features a low floor for spacious interiors. The vehicle, while eclipsed by the Cybercab in news headlines, still captured the imagination of many, as hinted at by X users posting AI-generated images of Robovan RV conversions with beds, kitchens and panoramic windows on social media platforms. One such render by Tesla enthusiast Mark Anthony reached over 300,000 views on X.
Elon Musk on the Robovan
Elon Musk addressed the Robovan’s low profile in October 2024, stating the van uses automatic load-leveling suspension that raises or lowers based on road conditions. The system maintains the futuristic look while handling uneven pavement, Musk wrote on X. The CEO also stated that the Robovan is designed to be very airy inside, which would be great for an RV.
“The view from the inside is one of extreme openness, with visibility in all directions, although it may appear otherwise from the outside. The unusually low ground clearance is achieved by having an automatic load-leveling suspension that raises or lowers, based on smooth or bumpy road conditions,” Musk stated.
-->Elluswamy’s response on X suggests that Tesla is considering a Robovan RV conversion, though it would be interesting to see how the company will make the vehicle capable of reaching campsites. The Robovan has a very low ground clearance, after all, and campsites tend to be in unpaved areas.
Tesla recently released Full Self-Driving (FSD) v14.2.1, its latest version, but the tinkering with Speed Profiles has perhaps gone too far.
We try to keep it as real as possible with Full Self-Driving operation, and we are well aware that with the new versions, some things get better, but others get worse. It is all part of the process with FSD, and refinements are usually available within a week or so.
However, the latest v14.2.1 update has brought out some major complaints with Speed Profiles, at least on my end. It seems the adjustments have gone a tad too far, and there is a sizeable gap between Profiles that are next to one another.
Tesla FSD v14.2.1 first impressions:
✅ Smooth, stress-free highway operation
✅ Speed Profiles are refined — Hurry seems to be limited to 10 MPH over on highways. Switching from Mad Max to Hurry results in an abrupt braking pattern. Nothing of concern but do feel as if Speed…— TESLARATI (@Teslarati) November 29, 2025
The gap is so large that changing between them presents a bit of an unwelcome and drastic reduction in speed, which is perhaps a tad too fast for my liking. Additionally, Speed Profiles seem to have a set Speed Limit offset, which makes it less functional in live traffic situations.
Before I go any further, I’d like to remind everyone reading this that what I am about to write is purely my opinion; it is not right or wrong, or how everyone might feel. I am well aware that driving behaviors are widely subjective; what is acceptable to one might be unacceptable to another.
Speed Profiles are ‘Set’ to a Speed
From what I’ve experienced on v14.2.1, Tesla has chosen to go with somewhat of a preset max speed for each Speed Profile. With ‘Hurry,’ it appears to be 10 MPH over the speed limit, and it will not go even a single MPH faster than that. In a 55 MPH zone, it will only travel 65 MPH. Meanwhile, ‘Standard’ seems to be fixed at between 4-5 MPH over.
This is sort of a tough thing to have fixed, in my opinion. The speed at which the car travels should not be fixed; it should be more dependent on how traffic around it is traveling.
It almost seems as if the Speed Profile chosen should be more of a Behavior Profile. Standard should perform passes only to traffic that is slower than the traffic. If traffic is traveling at 75 MPH in a 65 MPH zone, the car should travel at 75 MPH. It should pass traffic that travels slower than this.
Hurry should be more willing to overtake cars, travel more than 10 MPH over the limit, and act as if someone is in a hurry to get somewhere, hence the name. Setting strict limits on how fast it will travel seems to be a real damper on its capabilities. It did much better in previous versions.
Some Speed Profiles are Too Distant from Others
This is specifically about Hurry and Mad Max, which are neighbors in the Speed Profiles menu. Hurry will only go 10 MPH over the limit, but Mad Max will travel similarly to traffic around it. I’ve seen some people say Mad Max is too slow, but I have not had that opinion when using it.
In a 55 MPH zone during Black Friday and Small Business Saturday, it is not unusual for traffic around me to travel in the low to mid-80s. Mad Max was very suitable for some traffic situations yesterday, especially as cars were traveling very fast. However, sometimes it required me to “gear down” into Hurry, especially as, at times, it would try to pass slower traffic in the right lane, a move I’m not super fond of.
We had some readers also mention this to us:
The abrupt speed reduction when switching to a slower speed profile is definitely an issue that should be improved upon.
— David Klem (@daklem) November 29, 2025
After switching from Mad Max to Hurry, there is a very abrupt drop in speed. It is not violent by any means, but it does shift your body forward, and it seems as if it is a tad drastic and could be refined further.
