It’s always interesting reading comments and editorial commentaries on what makes Tesla Motors success so outrageous. After all, the company posts a loss, but manages to gain credibility, as well as the almighty investment dollar. The secret to the Tesla Motors success is simple.
In her excellent post on Seeking Alpha, Mira Inbar points to the three main reasons that explains Tesla Motors success. What is interesting to see is, why have others failed where a Californian startup didn’t? It all boils down to a simple and rational recipe a few other successful companies used in the past. You might remember them, Apple and Google?
Tesla Motors success recipe: Own the most expensive part of your business
The first part of the Tesla Motors success is that early on, Tesla decided to own its technology by assembling its own battery packs. Unlike other carmakers who chose to delegate this crucial part of an electric vehicle (EV) to battery maker, Tesla’s success is classroom 101 and its security track is exemplar. But to a traditional carmaker, the idea of assembling the battery pack of an EV is alien and foreign. They are geared toward building engines and slapping a body on top of. But a startup is unencumbered by this tradition. It sees a developing technology, senses the unspoken demand and finds solutions around the obstacles.
Tesla buys its 18650 cylindrical battery cells directly from Panasonic, but it develops the thermal management system, software, electronics, and mechanics around its pack in-house. The result is that no Model S has gone up in smoke on its own. Any accidents were caused by a third party. Unfortunately, the same can’t be said about traditional carmakers making modern EVs. Since you can’t own the manufacturing of gasoline, how about giving electricity to your clients for a measly extra $2,000 at purchase time?
Tesla Motors success recipe: Use available and proven technology
As mentioned above, Tesla Motors buys its commodity lithium-ion battery directly from Panasonic. This is the other ingredient to the Tesla Motors success. Certain carmakers decided to use different types of lithium batteries and left it up to the battery makers to design the thermal management and pack casing. Tesla rightfully felt this was more a carmaker’s responsibility. The result is that Tesla now has one of the best energy dense lithium-ion battery on the market that is always kept at a maximum operating temperature and its longevity speaks for itself.

Tesla’s second-generation cell designed in conjunction with Panasonic will catapult the company a few years ahead of the competition. In order to ensure the momentum, Musk simply plans to build a giant battery factory to continue owning the build process. The Gigafactory will assure success for the upcoming Tesla Model III and its new generation of cells.
Tesla Motors success recipe: Secure patient capital with a long-term view
The moral of the Tesla Motors success story is simple. There are plenty entrepreneurs in the world. There are plenty of startups, as well. But those that succeed first build the technology in-house and control it. They usually don't reinvent the wheel, they make smoother using everyday, affordable materials. They secure the right type of investors who understand the long-term potential. This reminds me of a company that followed a similar recipe: Apple. The Tesla Motors success recipe is the best modern example of how to build a successful company from the ground up.

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.
