To say that the Tesla Semi ruffled some feathers when it was unveiled last year is an understatement. Prior to the reveal of all-electric truck, questions were abounding about its viability as an alternative to conventional diesel-powered long-haulers. Even after the Semi’s specs and performance were announced, the vehicle still attracted a lot of skepticism.

During an event for Daimler’s e-Actos electric truck, for example, the company’s Head of Trucks, Martin Daum, noted that Elon Musk’s claims about the Semi’s 300 and 500-mile range are farfetched. Citing limitations in battery tech, Daum stated that “If Tesla really delivers on this promise, we’ll obviously buy two trucks — one to take apart and one to test because if that happens, something has passed us by. But for now, the same laws of physics apply in Germany and in California.” Jon Mills, a spokesman for engine maker Cummins Inc. noted back in August that while electrification is in the future of the trucking industry, the vehicles are not viable in their current state.  

Since it was unveiled, the Tesla Semi has been spotted traveling across the United States. Tesla unveiled two working prototypes of the Semi – one painted silver and the other matte black – when it unveiled the vehicle, and so far, both have been spotted testing on US roads. Both trucks were also sighted delivering cargo from Gigafactory 1 in NV to the Fremont factory in CA. Most recently, the silver Tesla Semi was sighted in Gigafactory 1, hauling a trailer and seemingly ready to transport cargo.

Tesla is not the only manufacturer coming up with a zero-emissions truck. As the transport industry starts accelerating its shift towards electrification, even prominent truck companies are coming up with their own green vehicles. Most of these vehicles exist as concepts for now, but they do give an idea of how veteran truckmakers are approaching the industry’s transition to the electric age.

Ford, for one, recently revealed the F-Vision concept, which is loaded to the teeth with cutting-edge tech, including an adaptable windshield that can lower and rise depending on the driver’s preference, as well as front lights that can be fully customized. Last month, Volvo introduced the Vera, its next-generation semi-trailer concept. Unlike Tesla and Ford’s truck, Volvo’s vehicle does not even have a driver’s cabin, as it is designed fully for autonomy. Startup trucking companies are also showcasing their offerings. Nikola Motors, for one, made headlines when it unveiled its long-range sleeper hydrogen-electric truck – the Nikola One – back in December 2016, and the company has since teased its next offering, a day cab called the Nikola Two.

There is little doubt that the upcoming electric truck concepts that have been unveiled so far are exciting vehicles in their own right. Inasmuch as this is the case, though, many of these impressive concepts feature technology that is still yet to be developed or refined. During the F-Vision’s unveiling, for one, Ford clarified that the truck is strictly a concept for now. Volvo’s Vera is a perfect fit for short-haul trips thanks to its 300 kWh battery that gives it a 187-mile range, but the vehicle can’t be deployed anytime soon since self-driving tech is still under development (even autonomous tech leader Waymo is reportedly struggling with its fleet’s real-world testing). Nikola’s hydrogen-electric trucks are powerful and boast long-range, but they would need a network of H2 refilling stations before they can be a viable alternative to diesel trucks. As a result, most zero-emissions truck concepts, including the Nikola One prototype, are yet to be sighted doing real-world tests on public roads. 

This is where the Tesla Semi is different. Among the upcoming electric trucks in the market, the Semi is the one undergoing consistent, intensive real-world testing. The vehicle has been spotted in multiple states since its unveiling, at times even visiting the sites of reservation holders like UPS, J.B. Hunt and PepsiCo. As it conducts its extensive real-world tests, the vehicle undergoes a consistent process of improvement. This was highlighted by Tesla’s Head of Automotive Jerome Guillen during the Q2 2018 earnings call, when he stated that several improvements have already been introduced to the electric truck since it was unveiled last year. Elon Musk even teased on Twitter that the Semi would likely have closer to 600 miles of range per charge. With this, it seems safe to infer that the production version of the Tesla Semi would be better than the prototype that is currently traveling across the country today. 

The Tesla Semi balances its features without overdoing it as well. It does not have the cloud-based autonomy of concepts like the Vera or the flashy variable front design of the Ford F-Vision, but ultimately, it does not need to have all these extra bells and whistles to become effective at what it’s designed to do. Tesla created the Semi to be a viable alternative to diesel-powered long-haulers, and if recent sightings and its consistent road tests is any indication, it appears that the vehicle is poised to be exactly that.

The Tesla Semi is expected to start production sometime in 2019. Recent reports have indicated that Tesla is planning on “earnestly” producing the Semi sometime in 2020.

Tesla intertwines FSD with in-house Insurance for attractive incentive

Every mile logged under FSD now carries a documented financial value—lower risk, lower cost—based on Tesla’s internal driving data rather than external crash statistics alone.

Tesla intertwined its Full Self-Driving (Supervised) suite with its in-house Insurance initiative in an effort to offer an attractive incentive to drivers.

Tesla announced that its new Safety Score 3.0 will automatically have a perfect score of 100 with every mile driven with Full Self-Driving (Supervised) enabled.

The change is designed to boost customers’ average safety scores and deliver noticeably lower monthly premiums.

The move marks the clearest link yet between Tesla’s autonomous driving technology and its proprietary insurance product. Tesla Insurance already relies on real-time vehicle data—such as acceleration, braking, following distance, and speed—to calculate a Safety Score between 0 and 100. Higher scores have long translated into cheaper rates.

Under the previous system, however, even brief manual interventions could drag down the average, frustrating owners who rely heavily on FSD. Version 3.0 eliminates that penalty for supervised autonomous miles, effectively treating FSD-driven segments as the safest possible driving behavior.

The incentive is immediate and financial. Drivers who keep FSD engaged for the majority of their trips will see their overall score rise, potentially shaving hundreds of dollars off annual premiums.

Tesla framed the update as a direct response to customer feedback, many of whom had complained that the old scoring model punished the very behavior it was meant to encourage.

For now, the program applies only to new policies in six states: Indiana, Tennessee, Texas, Arizona, Virginia, and Illinois.

Existing policyholders are not yet included, a point that drew swift questions from the Tesla community. Many owners in other states, including California and Georgia, expressed hope that the benefit would expand nationwide soon.

The announcement arrives as Tesla continues to roll out FSD Supervised updates and push for regulatory approval of more advanced autonomy. By tying insurance savings directly to FSD usage, the company is putting its own actuarial weight behind the technology’s safety claims.

Every mile logged under FSD now carries a documented financial value—lower risk, lower cost—based on Tesla’s internal driving data rather than external crash statistics alone.

Tesla has not disclosed exact premium reductions or the full rollout timeline beyond the six launch states.

Still, the message is clear: the more drivers trust FSD Supervised, the more Tesla Insurance will reward them. In an era when legacy insurers remain cautious about autonomous tech, Tesla is betting that its own data will prove the safest miles are the ones driven hands-free.

Tesla finalizes AI5 chip design, Elon Musk makes bold claim on capability

The Tesla CEO’s words mark a strategic shift. Tesla has long emphasized software-hardware co-design, squeezing maximum performance from every transistor. Musk previously described AI5 as optimized for edge inference in both Robotaxi and Optimus.

Tesla has finalized its chip design for AI5, as Elon Musk confirmed today that the new chip has reached the tape-out stage, the final step before mass production.

But in a brief reply on X, Musk clarified Tesla’s AI hardware roadmap, essentially confirming that the new chip will not be utilized for being “enough to achieve much better than human safety for FSD.”

He said that AI4 is enough to do that.

Instead, the AI5 chip will be focused on Tesla’s big-time projects for the future: Optimus and supercomputer clusters.

Musk thanked TSMC and Samsung for production support, noting that AI5 could become “one of the most produced AI chips ever.” Yet, the key pivot came in his direct answer: vehicles no longer need the bleeding-edge silicon.

Existing AI4 hardware, which is already deployed in hundreds of thousands of HW4-equipped Teslas, delivers safety metrics superior to human drivers for Full Self-Driving. AI5 will instead accelerate Optimus robot development and massive Dojo-style training clusters.

The Tesla CEO’s words mark a strategic shift. Tesla has long emphasized software-hardware co-design, squeezing maximum performance from every transistor. Musk previously described AI5 as optimized for edge inference in both Robotaxi and Optimus.

Now, with AI4 proving sufficient, the company avoids costly retrofits across its fleet while redirecting next-generation compute toward higher-value applications: dexterous robots and exponential training scale.

But is it reasonable to assume AI4 enables unsupervised self-driving? Yes, but with important caveats.

On the hardware side, the claim is credible. Tesla’s FSD stack runs end-to-end neural networks trained on billions of miles of real-world data. Internal safety data reportedly shows AI4-equipped vehicles already outperforming average human drivers by a significant margin in controlled metrics (collision avoidance, reaction time, edge-case handling).

Dual-redundant AI4 chips provide ample headroom for the driving task, leaving bandwidth for future model improvements without new silicon. Musk’s assertion aligns with Tesla’s pattern of over-provisioning compute early, then optimizing ruthlessly, exactly as HW3 once sufficed before HW4 scaled further.

Unsupervised autonomy, meaning Level 4 or higher, is not solely a compute problem. Regulatory approval remains the primary gate.

Even if AI4 achieves “much better than human” safety statistically, agencies like the NHTSA demand exhaustive validation, liability frameworks, and public trust.

Tesla’s supervised FSD has shown rapid gains in recent versions, yet real-world edge cases, like construction zones, emergency vehicles, and adverse weather, still require driver intervention in many jurisdictions. Competitors like Waymo operate limited unsupervised fleets, but only in geofenced areas with extensive mapping. Tesla’s vision-only, fleet-scale approach is more ambitious—and harder to certify globally.

In short, Musk’s post is both pragmatic and bullish. AI4 is likely capable of unsupervised FSD from a technical standpoint. Whether regulators and consumers agree, and how quickly, will determine if Tesla’s bet pays off.

The company’s capital-efficient path keeps existing cars relevant while pouring future compute into robots. If the safety data holds, unsupervised autonomy could arrive sooner than many expect.

Elon Musk signals expansion of Tesla’s unique side business

Long envisioning the Tesla Diner as more than a charging stop, Musk has clearly adopted the idea that the Supercharger and Restaurant combo is a good thing for the company to have. It’s a blend of classic American drive-in culture with futuristic Tesla flair, complete with a 1950s-inspired design, movie screens, and on-site dining.

Elon Musk has signaled an expansion of Tesla’s unique side business, something that really has nothing to do with cars or spaceships, but fans of the company have truly adopted it as just another one of its awesome ventures.

Musk confirmed on Wednesday that Tesla would build a new Diner location in Palo Alto, Northern California. After hinting last October that it “probably makes sense to open one near our Giga Texas HQ in Austin and engineering HQ in Palo Alto,” it seems one of those locations is being set into motion.

Long envisioning the Tesla Diner as more than a charging stop, Musk has clearly adopted the idea that the Supercharger and Restaurant combo is a good thing for the company to have. It’s a blend of classic American drive-in culture with futuristic Tesla flair, complete with a 1950s-inspired design, movie screens, and on-site dining.

He first floated broader expansion plans shortly after the LA opening in July 2025, noting that if the prototype succeeded, Tesla would roll out similar venues in major cities worldwide and along long-distance Supercharger routes.

Earlier hints included a confirmed second site at Starbase in Texas, tied to SpaceX operations, underscoring the Diner’s role in enhancing Tesla’s ecosystem behind vehicles.

The Los Angeles location on Santa Monica Boulevard in West Hollywood has served as a high-profile test case. Opened in July 2025 at 7001 Santa Monica Blvd., it features the world’s largest urban Supercharging station with 80 V4 stalls open to all NACS-compatible EVs, over 250 dining seats, rooftop views, and 24/7 service.

The retro-futuristic building replaced a former Shakey’s and quickly became a destination. Tesla reported selling 50,000 burgers in the first 72 days—an average of over 700 daily—drawing crowds with Cybertruck-shaped packaging, breakfast extensions until 2 p.m., and movie screenings.

Palo Alto stands out as a logical next step for several reasons. As Tesla’s longstanding engineering headquarters in the heart of Silicon Valley, the city is home to thousands of Tesla employees, engineers, and executives who could benefit from a convenient, branded gathering spot.

The area boasts high EV adoption rates, dense tech talent, and heavy traffic along key corridors, making a large Supercharger-diner an ideal fit for both daily commuters and long-haul travelers.

Proximity to Stanford University and the innovation ecosystem would amplify its appeal, potentially serving as a showcase for Tesla’s vision of integrated mobility and lifestyle experiences. It could be a great way for Tesla to recruit new talent from one of the country’s best universities.

If Tesla and Musk decide to move forward with a Palo Alto diner, it would build directly on the LA prototype’s momentum while addressing Musk’s earlier calls for expansion near core Tesla hubs.

Whether it materializes as a full confirmation or evolves from these hints remains to be seen, but the pattern is clear: Tesla is testing ways to make charging stops memorable. For EV drivers and enthusiasts alike, a Silicon Valley outpost could blend cutting-edge tech with nostalgic comfort, further embedding Tesla into everyday culture. As Musk’s comments suggest, the future of the Diner looks promising.
