This is a preview from our weekly newsletter. Each week I go ‘Beyond the News’ and handcraft a special edition that includes my thoughts on the biggest stories, why it matters, and how it could impact the future.
Tesla has tapped a new type of automotive glass from supplier AGP for the Plaid Model S, invoking the thought that everything, even the finest details of the vehicle, was considered a possible improvement for the company’s rebirth of the all-electric, flagship sedan.
Many months ago, Teslarati stumbled across a list of Tesla’s suppliers through international connections. These suppliers were shipping massive volumes of whatever product they were giving to Tesla on cargo ships, and we noticed that there was a company called AGP that was shipping windshields and other automotive glasses to the company’s Fremont Factory.
It turns out that AGP has been providing Tesla with automotive glass for several years. Back in 2016, AGP provided glass for the Model X’s panoramic roof and windshields. However, Tesla utilized AGC Automotive’s windshields for its cars, according to Investopedia.
AGP is a Peru-based company that specializes in all types of automotive glass, but what they’ve done for Tesla is especially interesting. The company has been in business for 50 years, but just like everything else, it changes, and the automotive industry is no different. As electric vehicles have become more mainstream, technologies surrounding the development of these new, sustainable automobiles are popping up left and right. AGP’s eGlass for electric and autonomous vehicles is no different.
Now, AGP says on its website that it collaborates “closely with the companies that are leading the new wave of the electric and autonomous vehicles of tomorrow.” When I first stumbled across AGP many months ago on the cargo ship list for Tesla, there was no indication that there was an official partnership, so I looked into it a tad further. I reached out to AGP and received a response that thanked me for my inquiry but refused to confirm or deny whether it was in any sort of professional relationship with Tesla. Ironically, AGP gave the answer we needed, because responding to me was all I needed to know.
Many may ask, “What’s the significance of what glass Tesla is using on its cars?” There are plenty of automotive glass suppliers out there that are worth their weight in gold, providing high-quality windshields and windows for vehicles on the road. Of course, consumers are going to want something that is relatively high quality, because nothing is worse than driving behind a tractor-trailer on the Interstate, just to have a chip or small crack on your windshield from something as tiny as a pebble. While strength is undoubtedly a need for all windshields, EVs require a slightly different bit of development.
One of the biggest focuses for EVs is their drag coefficient. Why is it so important? Because aerodynamics are crucial to the performance, range, and effectiveness of electric vehicles. As high-quality, long-range batteries are hard to come by in the EV sector, manufacturers look for every advantage they can get to achieve robust range ratings. While Tesla is the leader in EV range figures, the company is still looking for ways to get all of its vehicles to or near the 400-mile threshold.
Aerodynamics are a great way to do that. And Tesla undoubtedly worked extremely hard to achieve the best-in-class drag coefficient of .208, beating out the Lucid Air’s impressive .21 coefficient.
We knew aerodynamics was going to be a big part of the Plaid Model S when it was spotted at the Nürburgring two years ago. The vehicle was sporting a large spoiler, a huge rear diffuser, and the new eGlass from AGP is just another addition to Tesla’s attempts to make the Plaid Model S the most aerodynamic vehicle in its lineup.

We finally confirmed that AGP was providing the highly aerodynamic and EV-specific automotive glass to the Model S Plaid thanks to Tesla Raj, who took a picture of the manufacturer’s sticker on the window of the all-electric sedan at Tesla’s Delivery Event on June 10th. This all confirmed Teslarati’s discovery of AGP in its supplier list several months ago and also confirmed that the two companies had a partnership, despite AGP’s unwillingness to provide a comment (which we understood why!)

It makes me think about what Elon Musk may have needed to work on for the final week of Plaid development. When he had announced that the event was going to be delayed a week due to “tweaks,” I wondered whether it was software or hardware. While it was likely a software fix that needed to be addressed, it could have been related to the drag coefficient, which Tesla proudly displayed at the Plaid Event on the 10th. Nevertheless, the vehicle has finally been released to pre-orderers, and the fastest production car that has ever run the 1/4-mile drag is here, and it’s taking down anything in its path.
A big thanks to our long-time supporters and new subscribers! Thank you.
I use this newsletter to share my thoughts on what is going on in the Tesla world. If you want to talk to me directly, you can email me or reach me on Twitter. I don’t bite, be sure to reach out!

Tesla Summer Update begins rolling out: a look at the new features
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 this Robotaxi part for your personal car
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 Robotaxi gets sweeping but polarizing change
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
— Sawyer Merritt (@SawyerMerritt) July 27, 2026
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.
