The Tesla Semi’s economical advantage is frighteningly underestimated
The Tesla Semi has its own fair share of critics, and even today, some notable voices such as Microsoft co-founder Bill Gates believe that the Class 8 all-electric truck is not feasible. When one looks at the currently available information about the upcoming vehicle, however, one would see that the Tesla Semi is vastly underestimated.
One of the key criticisms surrounding the Tesla Semi is its weight, which skeptics would claim is far too much to be economically viable. Tesla has not shared any specifics surrounding the Semi’s weight, though the company did note that the vehicle consumes less than 2 kWh per mile. As noted by the OBF in a YouTube video, this would translate to the Semi likely having a battery that’s roughly around 600 kWh to 1,000 kWh, depending on whether the vehicle features a 300 or 500-mile range.
Considering that Tesla’s 100 kWh batteries typically weigh around 1,300 lbs, it could then be inferred that the Semi’s battery pack would weigh around 7,800 to 13,000 lbs. This is assuming that the Semi is equipped with the same batteries that Tesla had when the Class 8 truck was unveiled. If Tesla’s 4680 cells are involved, this weight could be optimized further, considering that the company’s custom batteries are lighter and more powerful.
Traditional diesel semitrailers typically weigh around 15,000 to 25,000 lbs, which means that the Semi would likely be at a disadvantage weight-wise. To address this disadvantage, Tesla would have to ensure that the rest of the Semi is made with light and durable materials. Tesla’s extensive experience as an EV maker plays a huge part in this, as the company could use all that it has learned during the design and rollout of the Model S,3,X,Y lineup to optimize the Semi’s weight.
If Tesla’s estimates are correct and its new 4680 batteries are lighter, and if the electric car maker uses innovations such as a structural battery pack on the Semi, the weight disadvantage of the Class 8 truck against diesel rivals becomes much smaller. Couple this with the fact that the Semi’s electric motors weigh far less than a large diesel engine and the all-electric Class 8 long hauler becomes a very compelling alternative to traditional semitrailers. Even the Semi’s higher price, which is expected to start at $180,000, becomes a moot point considering that electric vehicles need far less maintenance over their lifetime.
But this is not all. The Semi also stands to benefit from Tesla’s work with its Full Self-Driving suite, whose inner-city driving features are currently being rolled out to its initial batch of testers. Features such as Navigate on Autopilot, which would be incredibly useful for operators of the Tesla Semi, have already become refined over the years, and it would likely only take a matter of time before inner-city driving reaches the same state. When it does, capabilities that are unique to the Semi, such as its Convoy Mode, would likely become a “killer feature” that would make the vehicle a no-brainer against the competition.

SpaceX (NASDAQ: SPCX) got an absolutely crazy price target rating from Raymond James after the company experienced a tough first few weeks following its Initial Public Offering (IPO).
Despite the tumultuous start, SpaceX has plenty of believers, and the company’s massively successful Starship launch last Friday, its 13th test flight of the massive rocket, went so smoothly that Raymond James analysts pushed its price target on the company to roughly 7 times its current trading level.
SpaceX Starship just nailed something it’s never done before
The firm officially put a “Strong Buy” rating and an $800 price target on the stock. It currently trades at around $113. Its all-time high is $225.64, reaching this trading level shortly after shares first went public.
Raymond James’ price target is tied to the firm’s confidence after Starship’s 13th test flight. Analysts at the firm said it was an incremental step that reduces engineering risks, citing the widely successful heat shield test that CEO Elon Musk recently detailed, the smooth deployment of Starlink V3 satellites, and a successful in-space engine relight.
SpaceX also managed to see Starship splash down safely in the Indian Ocean, while the Super Heavy Booster fell down to the Gulf of America with no incidents.
It is interesting to see these launches have such a tremendous impact on the stock and what investors think of it. After SpaceX initially delayed the Starship launch last week, shares fell tremendously. Most probably did not realize that the stand-down is a standard practice, especially if everything is not perfect.
The mission was initially aborted due to an issue with Raptor engines. This was resolved, and Starship launched last Friday after another delay on Thursday, which was caused by weather.
Now that analysts have seen what SpaceX launches are capable of and how impressive the feat is, firms are adjusting their price targets accordingly, making it known that they have high expectations for the space exploration company.
Tesla CEO Elon Musk has responded to reports that Volvo is officially discontinuing the LiDAR sensor on two of its cars.
Volvo announced that it would officially scrap LiDAR systems on its EX90 and ES90 vehicles in various markets. In Norway, owners will get a €1,800 compensation for features that will never arrive due to this decision. There will be no option to remove the unit from vehicles, either.
The issue stems from Volvo’s supplier, Luminar, and its bankruptcy filing. Luminar will no longer be able to supply LiDAR units to Volvo for the EX90 and ES90, effectively axing any use the unit has on vehicles. Volvo will phase out the data collection processes via the LiDAR system, and it will not be utilized whatsoever.
Musk saw the story on X and responded, stating:
“I did try to warn them. Humans drive using neural nets and optical sensors. Same is true for robot cars.”

Musk has been publicly vocal about his disdain for LiDAR systems, once calling them “a fool’s errand,” as he has consistently kept the outlook that they are not needed for effective self-driving.
The typical example used as evidence for this by Musk is humans themselves: made with only eyes and memories, humans are capable of navigating a car by using what they can see and what they’ve personally experienced on the road.
Elon Musk argues lidar and radar make self driving cars more dangerous
“Same is true for robot cars,” Musk says, as Teslas have eight exterior cameras that help see everything surrounding the vehicle, and a neural network that analyzes behavior and tendencies with every mile driven.
Tesla is a vision-only self-driving company that ditched sensors and radar several years ago in favor of cameras. Behind this effort, the company has established a reputation for having one of the most robust self-driving platforms in the world.
Musk’s big bet with Tesla on its self-driving program’s strategy has widely paid off. Other companies continue to utilize things like LiDAR, radar, and sensors for effective self-driving, but Tesla has shown that there is more than one way to give consumers a strong and accurate driver assistance suite.
The real question is: who will be the first company to take Musk’s advice and attempt a self-driving platform based on cameras only, or even license FSD for themselves?
Tesla has started to deploy the 2026 Summer Update to owners across its fleet, and among the biggest changes are improvements to Navigation, a new startup animation for the Model 3 and Model Y, Caraoke scoring, and new capabilities for Grok.
As the update has started making its way to some cars, we can now see a few of the features operating in real-time. We will show you what some of the new features look like in this article, along with some additional details on what changed.
Not all of the new features in the 2026 Summer Update have quite made an appearance, but some of them have, so we’ll show those here:
New Animation Screen for 3/Y
Tesla is rolling out a new startup animation for Tesla Model 3 and Model Y owners. This is present in Launch Edition and Performance Model 3 and Model Y, but other trim levels do not have anything like this.

Owners can adjust the color associated with the startup animation to suit their preferences. It is a surprise that more automakers do not focus on this animation for their vehicles; it can be a great first impression piece and make the car immediately feel more luxurious.
Tesla has included this on more premium trims, but it is nice to see it on the Model 3 and Model Y.
Grok Improvements
Grok can now adjust more things in the car outside of the Navigation system. Now, drivers can adjust anything from climate to driving settings by simply speaking to the AI assistant in the car:

You don’t even have to push a button, either. Instead, you can just say “Hey, Grok,” if you have it enabled. That feature rolled out with the 2026 Spring Update just a few months back.
This is a great feature, especially pertinent for the Robotaxi platform, as there will be no buttons inside the Cybercab when it eventually starts giving rides to the public. It also broadens Grok’s capabilities, which were relatively limited in terms of vehicle setting adjustments beforehand.
