After staying under the radar for the past few months, Tesla’s matte black Semi prototype has been spotted on US roads once more. This time around, the all-electric long hauler was sighted pulling a trailer at the 40-stall Kettleman City Supercharger, located between San Francisco and Los Angeles.

The matte black Tesla Semi prototype was photographed by Tesla enthusiast James Douma, who noted that he spotted the vehicle on Wednesday afternoon. In a conversation with Teslarati, James stated that the vehicle seemed to be traveling alone, as the truck only had one person inside. Such an observation is quite interesting, considering that the silver Semi test mule traveling across the United States is usually accompanied by a team of engineers.

The Tesla enthusiast also remarked that he was informed by the staff of the Kettleman City Supercharger that it was the first time the matte black Semi prototype visited the location. The silver Semi test mule, on the other hand, has reportedly visited the site on four different occasions. The matte black Semi did not stay very long in the Kettleman site on Wednesday, though, as the vehicle promptly left the location soon after the photos were taken.

Sightings of the Tesla Semi during recent months have featured the silver test mule, which has been spotted in multiple states across the US. The matte black Semi, which also made an appearance at the vehicle’s unveiling back in November 2017, was last seen in April as it was being transported on a trailer heading east into I-80 in the Des Moines, IA area, near the headquarters of Ruan Transportation Management Systems, a reservation holder for the all-electric truck.

Prior to that, the matte black Semi was sighted a couple of times with its silver sibling, as the vehicles transported cargo between Tesla’s Fremont factory and Gigafactory 1 in Nevada. The last sighting of the matte black truck traveling alone was back in January, when it was filmed driving down a street in Sunnyvale, CA. While the electric car maker has not provided a reason behind the vehicle’s absence during the past few months, it is nonetheless refreshing to the see sleek prototype back on the roads once more.

The Tesla Semi has the potential to be the company’s most disruptive vehicle to date. Being designed to compete in the highly-competitive trucking industry, the Semi is equipped with several features that make it a viable and preferable alternative to diesel-powered vehicles. The Semi is propelled by four Model 3-derived electric motors that provide instant torque, allowing the Semi to go from 0-60 mph in 5 seconds flat without a trailer. The vehicle was also announced with a range of either 300 miles or 500 miles per charge, though Elon Musk later noted that truck’s long-range variant would have closer to 600 miles of range per charge.

The Tesla Semi is set to be supported by a network of Megachargers, which would be capable of replenishing 400 miles of range in as little as 30 minutes of charging. Unlike the Supercharger Network, which has a power output of roughly 120 kW, speculations are high that Tesla’s Megacharger will see around ten times the power levels. As Tesla conducts road tests of the Semi, though, the company has been adopting a temporary charging solution for the vehicle, using a series of Supercharger stalls connected to a hub, which is, in turn, connected to the all-electric truck.

SpaceX’s Starship V3 is almost ready and it will change space travel forever

SpaceX is targeting April for the debut test launch of Starship V3 “Version 3”

Published

SpaceX is closing in on one of the most anticipated rocket launches in history, as the company readies for a planned April test launch and debut of its next-gen Starship V3 “Version 3”.

The latest iteration of Starship V3 has a slightly taller Super Heavy booster and Starship upper stage than their predecessors, and produce stronger, more efficient thrust using SpaceX’s upgraded Raptor 3 engines. V3 also features increased propellant capacity, targeting a total payload capacity of over 100 tons to low Earth orbit, compared to around 35 tons for its predecessor. With Musk’s lifelong aspiration to colonize Mars one day, the increased payload capacity matters enormously, because Mars missions require moving massive amounts of cargo, fuel, and eventually, people. But the most critical upgrade may be orbital refueling. SpaceX’s entire deep space architecture depends on moving large amounts of propellant in space, and having orbital refueling capabilities turn Starship from just a rocket into a true transport system. Without it, neither the Moon nor Mars is reachable at scale.

A fully reusable Starship and Super Heavy, SpaceX aims to drive marginal launch costs down and at a tenfold reduction compared to current market leaders. To put that in perspective, getting a kilogram of cargo to orbit today costs thousands of dollars. Bring that number down far enough and space stops being an exclusive domain. That price point unlocks mass deployment of satellite constellations, large-scale science payloads, and affordable human transport beyond Earth orbit. It also means the Moon stops being a destination we visit and starts being one we inhabit.

Elon Musk pivots SpaceX plans to Moon base before Mars

NASA expects Starship to take off for the Moon’s South Pole in 2028, with the ultimate goal of establishing a permanently crewed science station there. A successful V3 flight this spring keeps that timeline alive.  As for Mars, Musk has shifted focus toward building a self-sustaining city on the Moon first, arguing that the Moon can be reached every 10 days versus Mars’s 26-month alignment window. Mars remains the horizon, but the Moon is the proving ground.

Elon Musk hasn’t been shy with hyping the upcoming Starship V3 launch. In a social media post on Wednesday, he confirmed the first V3 flight is getting closer to launch. SpaceX also announced its initial activation campaign for V3 and Starbase Pad 2 was complete, wrapping up several days of cryogenic fuel testing on a V3 vehicle for the first time. The countdown is on. April can’t come soon enough.

Tesla is rolling out a new and long-awaited feature to the Cybertruck all-electric pickup, and it is a safety addition geared toward pedestrian and cyclist safety, as well as accidents with other vehicles.

Tesla has announced the rollout of its innovative anti-dooring protection feature to the Cybertruck via the 2026.8 software update.

This safety enhancement uses the vehicle’s existing cameras to detect approaching cyclists, pedestrians, or vehicles in the blind spot while parked. Upon attempting to open a door, if a hazard is detected, the system activates: the blind spot indicator light flashes, an audible chime sounds, and the door will not open on the initial button press.

Drivers must wait briefly and press the button again to override, providing crucial seconds to avoid an accident.

The feature, also known as Blind Spot Warning While Parked, comes standard on every new Model 3 and Model Y, and is now extending to the Cybertruck. Leveraging Tesla’s vision-based system without requiring new hardware, it represents a cost-effective software solution that builds on community suggestions dating back to 2018.

This technology addresses the persistent danger of “dooring,” where a driver opens a car door into the path of a passing cyclist or pedestrian.

Tesla implemented this little-known feature to make its cars even safer

Dooring incidents are alarmingly common in urban environments.

According to Chicago data, in 2011 alone, there were 344 reported dooring crashes, accounting for approximately 20 percent of all bicycle crashes in the city, nearly one incident per day.

While numbers have fluctuated (dropping to 11 percent in 2014 before rising again), dooring consistently represents 10-20 percent of bike-related crashes in major cities.

A national analysis of emergency department data estimates over 17,000 dooring-related injuries treated in the U.S. over a decade, with many involving fractures, contusions, and head trauma, particularly affecting upper extremities.

By automatically intervening, Tesla’s system not only protects vulnerable road users but also safeguards its owners from potential liability and enhances overall road safety.

As cities promote cycling for sustainable transport, features like this demonstrate how advanced driver assistance and camera systems can evolve beyond highway driving to everyday urban scenarios.

Enthusiastic responses on social media highlight appreciation for the proactive safety measure, with some calling for broader rollout to older models where hardware permits. Tesla continues to push the boundaries of vehicle safety through over-the-air updates, making its fleet smarter and safer over time.

Tesla is planning to unveil the Roadster in late April after years of waiting. But the wait might be worth it, according to Travis Kalanick, the founder of Uber, who recently shed some light on his expectations for the all-electric supercar.

We all know the Roadster is supposed to have some serious capability. CEO Elon Musk has said on numerous occasions that the Roadster will be unlike anything else ever produced. It might go from 0-60 MPH in about a second, it might hover, it might have SpaceX cold gas thrusters.

However, the constant delays in the Roadster program and its unveiling event continue to send Tesla fans into confusion because they’re just not sure when, or if, they’ll ever see the finished product.

Perhaps the wait will be worth it, especially according to Uber founder Travis Kalanick, who recently teased the Roadster’s potential capabilities based on what he has heard from internal Tesla sources.

Kalanick said on X:

Musk has said this vehicle is not going to be geared for safety, and that, “If safety is your number one goal, do not buy the Roadster.”

There has been so much hype regarding the Roadster that it is hard to believe the company could not come through on some kind of crazy features for the vehicle.

Elon Musk just dropped a huge detail on the Tesla Roadster

However, the latest delay that Tesla put on the unveiling event is definitely eye-opening, especially considering it is the latest in a series of pushbacks the company has put on the vehicle for the past several years.

Tesla has made several jumps in the Roadster project over the past few months, as it has ramped up hiring for the vehicle and also applied for a patent for a new seat design.

The car has been a back-burner project for Tesla, as it has been focusing primarily on autonomy and the rollout of Robotaxi and Cybercab. Additionally, its other vehicle projects, like the Model 3 and Model Y refreshes, took precedence.

Tesla still plans to unveil the Roadster next month, so we can hope the company can stick to this timeframe.
