Tesla Semi spotted Supercharging thousands of miles from factory as real-world tests continue
Tesla’s all-electric Semi truck continues its real-world testing, with the long-hauler recently being spotted nearly 2,000 miles away from the Fremont factory at the Catoosa, Oklahoma Supercharger station, off of Interstate 44. The electric truck’s recent sighting comes a day after the vehicle was spotted cruising in New Mexico on I-40, more than 600 miles away.
The Catoosa sighting was shared on the r/TeslaMotors subreddit by Model 3 reservation holder u/JohnFitzgeraldSnow, who was able to take a photo of the truck. The electric car enthusiast mentioned that the all-electric Semi was only using a single charging cable while it was attached to a Supercharger stall. The truck was reportedly accompanied by a group of Tesla employees as well.
The latest sightings of the Semi are yet another sign that Tesla is doing some extensive real-world testing on the electric long-hauler. Among Tesla’s vehicles, the Semi would likely be the one that would rack up miles the fastest, considering that it would be tasked to transport cargo over long distances on an everyday basis. The state of the Tesla Semi in its recent sighting is proof of this, as the vehicle was pretty much covered all over with bugs from the freeway.
The Semi is designed to disrupt the trucking industry the way the Model 3 is designed to disrupt the mainstream auto market. The specs of the Semi, particularly its 500-mile range, have caught the ire of the company’s critics. Daimler’s head of trucks Martin Daum even alleged that the Semi’s quoted specs defy the laws of physics. This was laughed off by Elon Musk during the Q1 2018 earnings call, when he stated that Tesla could make a truck with 500 miles of range even with its current battery technology.
Being the largest vehicle in Tesla’s lineup, the Semi is designed to be supported by a network of high-powered Megachargers. Elon Musk noted during the Semi’s unveiling last November that the Megachargers would be capable of replenishing 400 miles of range in as little as 30 minutes of charging. The actual specs of the Megacharger have not been announced as of date, but there is a good chance that it would be roughly ten times as powerful as Tesla’s ~120 kW Superchargers.
Since being unveiled, the Tesla Semi has received a strong, positive response from several high-profile customers. In the United States alone, companies such as UPS, FedEx, Anheuser-Busch, and PepsiCo have all placed reservations for the vehicle. To prepare for the rollout of the electric trucks on America’s roads, Tesla has started building the initial charging infrastructure for the Semi. Reports emerged earlier this year that Tesla is partnering with several of the Semi’s reservation holders to build charging stations in key locations frequently traveled by fleet operators. The stations, which would likely be the first Megachargers, will be spaced close enough together so that the Semi has enough range to complete its routes.
The Tesla Semi is expected to start production sometime in 2019, and though the company has not announced where the vehicle would be manufactured, there is a good chance that the electric long-hauler’s production would be a lot smoother. The Semi, after all, shares several components with the Model 3, such as its electric motors. Considering that Tesla has learned a lot of lessons from the ramp of the Model 3, there is a good chance that the Semi might make it to market earlier than expected.
Tesla is bolstering its Cybercab fleet with the State of Texas’s regulatory bodies ahead of the planned launch of the all-electric ride-hailing vehicle this Thursday.
Seven purpose-built Tesla Cybercabs have been added to Texas’s official automated vehicle registry, appearing in the Texas Motor Carrier Credentialing System (TxMCCS) public lookup just three days before Tesla’s invite-only Cybercab launch event in Austin on September 3.
The records, visible through TxDMV’s Motor Carrier and Automated Motor Vehicle Operator Lookup, list seven 2026 Tesla Cybercabs under Tesla Robotaxi, LLC. Their VINs begin with the 5YJA prefix, distinct from the 7SAYG Model Y robotaxis that already dominate Tesla’s Texas fleet.
Community trackers that scrape the same public database recorded the new entries on August 31, bringing Tesla’s authorized Texas robotaxi total to 276 vehicles: 269 Model Ys and the seven Cybercabs:

Texas Senate Bill 2807, which took effect in late May 2026, created a self-certification framework for commercial Level 4 operations. Operators file through TxMCCS, attest to SAE Level 4 capability, maintain insurance, and keep an active vehicle list.
Tesla completed that process months earlier for its existing Model Y Robotaxi service, which has carried paying passengers in Austin, Dallas, Houston and other markets. Adding the Cybercabs to the same authorization means the new two-seat, steering-wheel-free vehicles are now legally recognized for commercial use on Texas roads.
The timing is deliberate as Tesla scheduled the September 3 event at its Austin campus after sending invitations to selected Robotaxi riders and other guests. The company has described the evening as a chance to “experience the future of full autonomy” and plans to livestream it.
Production Cybercabs, which lack pedals and a steering wheel, have been rolling off the Giga Texas line for months; some earlier examples still carried temporary driver controls for data collection. Registering a small fleet of the finished design immediately before the public event signals that Tesla intends to move the purpose-built vehicle from factory and test tracks into the same Robotaxi app already used by Model Y passengers.
The seven units remain a tiny fraction of Tesla’s overall Texas authorization and far smaller than competing fleets. Registration does not automatically equal unsupervised public rides; it is the legal prerequisite.
Still, the sudden appearance of Cybercab VINs in the state’s lookup system, after a year of Model Y-only listings, is the clearest official confirmation yet that Tesla’s dedicated robotaxi hardware is entering the regulatory pipeline at the same moment the company is preparing to show it to invited guests and a global livestream audience.
Whether those seven vehicles appear at the September 3 event or begin carrying passengers shortly afterward, their presence in TxMCCS marks a concrete regulatory step that has been anticipated since the Cybercab concept was first revealed.
Tesla has expanded the operational geofence for its driverless Robotaxi service in Austin, Texas, marking the first such increase in some time. The updated Service Area for Robotaxi in Austin now spans about 288 square miles and is roughly 9 percent larger than the previous boundary.
This incremental growth adds approximately 24 square miles of coverage, bringing the prior zone of roughly 264 square miles into a broader footprint that better serves northern suburbs.
The expansion extends the geofence northward toward Pflugerville along the US 183 corridor, incorporating additional neighborhoods north of the Domain and areas such as Mesa Park. These additions include higher-end residential and commercial districts that previously sat just outside the allowed operating zone.
Riders can now request unsupervised trips that begin or end in these newly included locations, provided the entire route remains inside the digital boundary:

Tesla first launched public Robotaxi operations in Austin in mid-2025 with a modest initial zone of about 20 square miles. Subsequent enlargements in 2025 and early 2026 steadily grew the map until it covered much of the metropolitan area.
After the last major update roughly ten months earlier, the company held the boundary steady while it collected additional miles and refined the FSD suite.
The modest nine percent increase still matters for daily utility. Longer trips become possible, more residents gain access, and the fleet can accumulate more diverse real-world data across new road types and traffic patterns. Observers note that the added territory aligns with existing Tesla service infrastructure, which could support more efficient vehicle staging in the North end of Austin.
Although the geofence has grown, Tesla continues to operate a relatively small unsupervised fleet in the city. The company has emphasized safety and software readiness over rapid geographic scaling. This latest map update signals that Tesla remains committed to expanding Robotaxi availability in its home market as it prepares for further software improvements and potential Cybercab deployments.
The 288-square-mile zone now gives Austin riders one of the larger driverless service areas currently available in the United States.
Tesla’s 2026 Summer Update turns Grok from a talking companion into a true in-car controller, with considerably expanded capabilities. Where the assistant once answered questions and handled navigation, it can now operate hardware and software through ordinary speech, including several requests at the same time.
Grok has become incredibly robust over the past few quarters, and this new ability that Tesla has included with its Summer Update is perhaps the clearest sign of just how capable it has become.
You can issue many commands to Grok at once, and each will be taken care of: anything from headlight control to climate adjustments to mirror folding can now all be taken care of with a simple sentence spoken toward Grok:
This is cool, you can now give Grok a ton of commands at once in your Tesla and it’ll do them all together.
The commands I gave:
• Fold mirrors
• Turn on wipers to fastest setting
• Change temp to 65°
• Open self-driving app
• Open gloveboxComes with Tesla’s 2026 Summer… pic.twitter.com/drZxoHrknv

Here’s another example I used in my Model Y:

Tesla’s official Release Notes list the core powers of Grok’s new capabilities: Grok can place phone calls from a paired phone, search a streaming service and queue music, adjust climate, and search the Controls panel. Drivers can also ask it questions about the vehicle or the latest features included in a recent software update.
It can also take care of driving settings, dynamics, and other relevant preferences that deal with how the car operates and handles.

It’s also more of a use case than a novelty feature. Grok was great for learning about something that was being pondered while Full Self-Driving was taking care of the major automotive responsibilities, but it did have some useful functionality when it came to navigation.
Another less-noted improvement is the swift transition that Grok has from thinking of its answer to giving you one. In the past, it would take a few seconds for Grok to truly come up with a valuable response. It now seems that it is improving, at least slightly.
