The Boring Company’s innovations take center stage at Hawthorne test tunnel opening event
Two years ago, Elon Musk founded a tunneling startup aimed at battling what he creatively described as “soul-destroying traffic.” Musk’s idea was simple — traffic congestion can be addressed by using underground tunnels where vehicles can travel at extremely fast speeds on electric skates. Hence, a startup aptly named The Boring Company was born.
Since then, the tunneling company has acquired a high-profile project in Chicago, developed low-cost bricks from tunneling rocks, and completed its first test tunnel. Constructed on the backyard of the SpaceX headquarters, the Boring Company’s Hawthorne test tunnel was unveiled on Tuesday in an opening party, complete with entertainment, fun activities, and a medieval watchtower overlaid with Boring Bricks.
Being smaller in diameter than traditional tunnels, The Boring Company’s projects are more cost-effective and faster to construct. Its 1.14-mile Hawthorne tunnel, for example only cost ~$10 million to build, including internal infrastructure, lighting, comms/video, safety systems, ventilation, and tracks. Conventional tunneling projects, which involve larger tunnels and traditional digging methods, could cost as much as $1 billion per mile.
Elon Musk conducted an information session to members of the press prior to the official start of the unveiling. During the meeting, Musk discussed some updates about the startup’s concepts. For one, Musk noted that The Boring Company had changed its idea of using electric skates to propel cars. Instead of using pre-made electric skates, the company is now using the vehicle as the skate itself.
“There won’t be a skate — no more skate. The vehicle is the skate,” Musk said.

The Hawthorne test tunnel would be utilizing the Loop System, which is designed to accommodate cars and passenger pods. During the Q&A, Musk noted that the Loop is a step towards the eventual creation of Hyperloop, which utilizes pods traveling inside low-pressure tubes at speeds of up to 700 mph. “The loop is a stepping stone toward Hyperloop. Loop is for transport within a city. And Hyperloop is transport between cities,” Musk said.

Apart from referencing Hyperloop transportation, Musk further discussed other possible uses for The Boring Company’s technology. Reiterating an idea he expressed during a “fireside chat” in Los Angeles with LA Mayor Eric Garcetti, Musk noted that the Boring Co.’s tunnels could also be used for utilities such as water lines. Due to the tunnels’ construction and design, Musk stated that “If a water main breaks, it floods through the tunnel one end, and gets pumped out the other.” This would allow cities to address utility issues without much hassle.
Just like Musk’s other companies like Tesla and SpaceX, The Boring Company is in a constant process of innovation. The startup, for one, continues to design and develop its third-generation Tunnel Boring Machine. Once operational, the new TBM would be capable of digging 15 times faster than a conventional boring machine. Apart from using a fully-electric system to increase power, The Boring Machine is also designing the upcoming TBM’s cutter head to process more dirt. In yet another step away from convention, the tunneling startup is also creating reinforcement segments on site using the dirt excavated from the tunnel itself.
Musk has noted that The Boring Company’s tunneling projects are already attracting a lot of interest, stating that “we have more demand on tunnels than we can satisfy,” and that “we have people hounding us to invest nonstop.” In a flourish of classic Elon Musk humor, the Tesla and SpaceX CEO noted that “it’s kinda ridiculous how much interest we’ve had in investing in Boring Company.” Elaborating further, Steve Davis, the CEO of the Boring Company, added that the startup receives “greater than 5 and less than 20 requests per week from different municipalities and stakeholders.”
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.
