Tesla Cybertruck makes a tight squeeze through Boring Company tunnel
The Tesla Cybertruck navigated The Boring Company’s Hawthorne test tunnel as it was driven by veteran talk show host Jay Leno and Elon Musk in the passenger’s seat. The episode of Jay Leno’s Garage on CNBC revealed that the Cybertruck was fully capable of navigating the startup’s rather narrow tunnel. It was a tight fit, but the all-electric pickup was able to traverse the entire length of the test tunnel without any issues.
The highlight of the episode has been teased in the past. After the trailer for the sixth season of Jay Leno’s Garage was released in late April, the short television spot previewed the massive Cybertruck dropping into the Hawthorne test tunnel.
The event was previewed once more by Leno earlier this month, when the host was featured in Spike Feresten’s podcast to talk about his experience in the Cybertruck. After describing the ride, Leno said Musk offered him a journey through the Hawthorne tunnel. Describing the trip vaguely to not give away too much, the former late-night show host explained a super tight fit that allowed for about a quarter-inch of space on each side of the Cybertruck.

The episode of Leno’s show revealed that the fit was extremely tight and restricted, and Leno was undoubtedly wary of his surroundings while navigating the all-electric pickup through the tunnel. Musk, for his part, seemed relatively relaxed.

“It will be quite interesting to see if we can actually fit it down there,” Musk said.
After navigating the truck within the tunnel, Musk gave Leno the finer points of the Hawthorne tunnel and its design, explaining that it was a test tunnel for the Boring Company’s future projects. But Leno’s description of the ride seemed to be slightly different than a carefully navigated stroll that was filmed and put into the final cut of the episode.

Leno told Feresten during his interview on the podcast, “We drive the Cybertruck, we barely get it into the tunnel, and now we’re going like 50 or 60 miles per hour through the tunnel with a quarter-inch on each side.”
After exiting the tunnel, Leno extended his congratulations to Musk, offering him luck that the next twelve years would be like the last twelve. Since 2008, Tesla has built itself up from a small startup with a slight chance of success to one of the most valuable car companies in the world.
Leno’s absurd collection of cars would make any automotive enthusiast jealous. However, it seems that Tesla cars always have struck a different tone with the veteran host, even speaking highly of the company’s electric vehicles in the past. This time around, the Cybertruck certainly seemed to win Jay over. Its design and performance are unlike any pickup on the market today, something Leno identified during his short stroll through Los Angeles in the Cybertruck.

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.
