Tesla Semi cabin’s Model 3-inspired elements showcased in new video
A video featuring a rare look at the Tesla Semi’s cabin was recently uploaded on YouTube. As could be seen in the short clip, the all-electric long-hauler features some compelling design elements, from components inspired by the Model 3 to a mysterious pedal beside the vehicle’s brakes.
The Semi’s recent video was uploaded by Moldova-born YouTuber and truck enthusiast Andrew Black, who was able to get up close and personal with the all-electric long-hauler. The Tesla Semi in the video was hauling a trailer from Xtra Lease Trailers, suggesting that the truck was in a transport run when the footage was taken.
Immediately noticeable from the Tesla Semi’s cabin was how roomy and spacious it was. Even with the jumpseat for the passenger unfolded, the electric truck still has a very roomy feel. Upfront, several design elements pop up, the most notable of which is an air vent inspired by the Model 3. The Tesla Semi also features a clean, minimalistic, end-to-end dashboard that runs from one side of the vehicle to the other.
In a lot of ways, the Tesla Semi actually borrows some components from the Model 3. Apart from its end-to-end HVAC system, the Semi also uses the same electric motor as the compact electric car (it has four Model 3-derived electric motors). The Semi is fitted with what appears to be the door handles of the Model 3, as well as dual touchscreen controls that invoke the compact electric car’s landscape-oriented center touchscreen. The size of the Semi’s two touch panels have not been mentioned by Tesla, but based on Black’s recent video, it seems safe to assume that its dual displays are also 15-inch panels.
One thing that grabs the attention from the video, however, was a rather mysterious pedal that could be seen near the 1-minute mark. As the camera was being panned across the Tesla Semi’s cabin, the all-electric truck’s accelerator and brake pedals could be seen prominently. To the left of the brakes, however, was seemingly another pedal. Unlike the dead pedal found in the Model S, Model X, and Model 3, the third pedal in the Semi was rather small, and it looked functional. Some members of the r/TeslaMotors subreddit have weighed in on the mysterious pedal, with a number suggesting that it could be a mechanical parking brake.

Just like the Model 3, the Tesla Semi has the potential to be an incredibly disruptive vehicle. The electric truck is a Class 8 truck equipped with four Model 3-derived electric motors, which enable it to accelerate from 0-60 mph in 5 seconds flat without cargo. With a full 80,000-lb load, the Semi is still capable of hitting highway speed in 20 seconds, far quicker than comparable diesel-powered semi-trailers.
The Tesla Semi is currently being tested and driven across the United States. Just recently, the electric long-hauler was spotted driving over the Golden Gate Bridge on its way to Santa Rosa, CA. According to Tesla’s Tesla’s VP of Truck Programs Jerome Guillen in his LinkedIn profile, the Semi was headed to Santa Rosa to visit some local customers.
Tesla CEO Elon Musk and CTO JB Straubel revealed during the Q1 2018 earnings call that the Semi currently has around 2,000 reservations from businesses within and outside the United States. In the United States alone, several high-profile companies have already placed orders for the electric truck, including PepsiCo, FedEx, and Anheuser-Busch. Outside the United States, grocery chain ASKO from Norway has placed reservations for the long-hauler, as well as waste management conglomerate Bee’ah from the Middle East, among others.

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.
Tesla briefly offered one Robotaxi part in its Parts Catalog for your personal car, only to remove it just a short time after it was first noticed.
Tesla’s Robotaxi camera washer apparatus was briefly available for purchase on the company’s Online Parts Catalog. The camera washer was first noticed on Model Y Robotaxi vehicles about six months ago in Austin.

First noticed by Not a Tesla App, the Camera Washer entries appeared for the new “Juniper” Model Y under a category called “Halo,” which has also now disappeared. Interestingly, Halo probably is related to Tesla’s internal “Project Halo,” which was a project that aimed to retrofit customer-owned Model Ys into functional Robotaxis.
This hardware addition would likely be required for the vehicle to operate as a Robotaxi, as the Camera Washer seems to be a non-negotiable part of the vision-based system Tesla utilizes for self-driving efforts.
However, this part has since been removed and is no longer visible on the EPC.
-
Now the true question lingers: Why would Tesla add this Camera Washer to the Model Y parts catalog? Is it planning to make it available for owners to utilize on their own cars for personal use, or will it become a prerequisite for Robotaxi operation in customer-owned cars?
While discussing the upgrade options for Hardware 3 vehicles during the Q1 Earnings Call, Tesla CEO Elon Musk had said that the company could establish small, satellite shops that would upgrade cameras and self-driving computers. Perhaps this same strategy could be utilized for vehicles that want to be included in Robotaxi but do not have the correct hardware.
AI4 is currently represented as capable of unsupervised self-driving, and the same was said about HW3 at one point, only for Tesla to admit last quarter that it would, unfortunately, not be possible. Perhaps AI4 vehicles might need this camera washer as a prerequisite, just as HW3 cars will need that camera and computer upgrade.
This could be the first hint of that’s where we are headed.
Tesla has started rolling out a broader change to the ride experience for its Robotaxi fleet by silencing turn signals, but the change is certainly polarizing.
Tesla has generally made it clear that its purpose-built ride-hailing platform, Robotaxi, will cater to the rider in nearly every way possible. This includes having climate preferences, music, and other personal settings loaded up in the car as the rider enters.
But Tesla is taking it a step further by muting turn signal chimes altogether, a change that appears to be a way to make the ride more peaceful:
Tesla has finally turned off the blinker/turn signal noises in their Model Y Robotaxis.
This is a small update, but will definitely be noticeable for riders. It didn’t really make much sense to leave the turn signal sound on when it’s Unsupervised. pic.twitter.com/ITwx60PAMO

However, there are a handful of people who are not thrilled about this change. Turn signals are a conditioned part of the human mind for those who ride in a car regularly.
-
Taking a turn without one feels strange and odd, and not hearing it click while activated could set off some alarms for riders, who might use the noise as confirmation that other drivers know of their intention to turn.
I kind of like it being on, threw me off when riding with Zoox who has had it disabled
— Dan Burkland (@DBurkland) July 27, 2026
Turn signal noises are still audible in customer cars, so if you use FSD in your personal vehicle, you will still hear the turn signal.
The move is certainly one that is unique, but not one that separates it from other ride-sharing services. In a normal car, the clicking sound confirms to the driver that the blinker is active. In a fully driverless Robotaxi, that feedback serves no purpose for passengers, other than peace of mind.
