Tesla Semi spotted on public streets between Fremont factory and HQ
The first known sighting of the Tesla Semi truck on public roads has been posted to YouTube. The video captures Tesla’s matte black Semi driving down a local street in Sunnyvale, California, a halfway point between Tesla’s headquarters in Palo Alto and its Fremont factory. While the sighting was very brief, several interesting things about the truck stood out.
For one, the massive long-hauler is really quick for a vehicle of its size. While we can’t identify the actual speed of the all-electric truck in the video, the sounds from its four Model 3-derived electric motors is unmistakable. Apart from this, the recently spotted Tesla Semi was also fitted with a pair of standard side mirrors — mandated accessories which were absent on the long-hauler when it was unveiled last year.
The Tesla Semi’s official USDOT number of 2298288 can be seen in the driveby video. Apart from the driver of the electric truck, a passenger could also be seen in the cabin of the vehicle. The sighting seemed to have happened in Elko Drive, Sunnyvale, CA, as evidenced by the presence of UPS and a building for BT Express Liquidators in the video.
While very little could really be determined from the short YouTube clip, it is very likely that the matte black Tesla Semi is being used by the California-based electric car maker and energy company. Tesla, after all, has stated that it would be the customer of its own product. Thus, there is a pretty good chance that the stealth-black electric long-hauler spotted on Sunnyvale was part of Tesla’s own fleet for its supply chain.
The Tesla Semi is poised to be a disruptive vehicle in the trucking industry the same way the Model 3 is for the consumer car market. During its official launch, Tesla CEO Elon Musk made it a point to show that the Tesla Semi is indeed a different breed of long-hauler compared to similar Class 8 vehicles.
Musk, for one, noted that the massive electric truck could haul 80,000 pounds (the industry maximum) of cargo faster than any other competing diesel truck of the same class. With a full load, the Tesla Semi can still accelerate from 0-60 mph in just 20 seconds. A Class 8 diesel truck? Far, far longer. The truck is also equipped with a driving-assist feature to support Convoy Mode, which would give truckers a far easier time when traveling long distances.
Since it was unveiled in a high-profile launch event last November, the Tesla Semi has steadily gained a lot of supporters. Over the past few months, large corporations, from local conglomerates and international firms, have placed orders for the electric long-hauler. While orders for the Tesla Semi continue to be reported, however, sightings of the semi truck are still incredibly rare. With that in mind, enjoy the first ever sighting of the Tesla Semi on public streets below.
Tesla made a change to the Cybertruck, and nobody noticed. But to be fair, nobody could have, but it was revealed by the program’s lead engineer that it was aimed toward simplifying manufacturing through a minor change in casting.
After the Cybertruck was given a Top Safety Pick+ award by the Insurance Institute for Highway Safety (IIHS), for its reputation as the safest pickup on the market, some wondered what had changed about the vehicle.
Tesla makes changes to its vehicles routinely through Over-the-Air software updates, but aesthetic changes are relatively rare. Vehicles go through refreshes every few years, as the Model 3 and Model Y did earlier this year. However, the Cybertruck is one of the vehicles that has not changed much since its launch in late 2023, but it has gone through some minor changes.
Most recently, Wes Morrill, the Cybertruck program’s Lead Engineer, stated that the company had made a minor change to the casting of the all-electric pickup for manufacturing purposes. This change took place in April:
We made a minor change on the casting for manufacturability in April. Our Internal testing shows no difference in crash result but IIHS only officially tested the latest version

The change is among the most subtle that can be made, but it makes a massive difference in manufacturing efficiency, build quality, and scalability.
Morrill revealed Tesla’s internal testing showed no difference in crash testing results performed by the IIHS.
The 2025 Cybertruck received stellar ratings in each of the required testing scenarios and categories. The Top Safety Pick+ award is only given if it excels in rigorous crash tests. This requires ‘Good’ ratings in updated small and moderate overlap front, side, roof, and head restraints.
Additionally, it must have advanced front crash prevention in both day and night. Most importantly, the vehicle must have a ‘Good’ or ‘Acceptable’ headlights standard on all trims, with the “+ ” specifically demanding the toughest new updated moderate overlap test that checks rear-seat passenger protection alongside driver safety.
Tesla has entered an interesting situation with its Full Self-Driving suite in California, as the State’s Department of Motor Vehicles had adopted an order for a suspension of the company’s sales license, but it immediately put it on hold.
The company has been granted a reprieve as the DMV is giving Tesla an opportunity to “remedy the situation.” After the suspension was recommended for 30 days as a penalty, the DMV said it would give Tesla 90 days to allow the company to come into compliance.
The DMV is accusing Tesla of misleading consumers by using words like Autopilot and Full Self-Driving on its advanced driver assistance (ADAS) features.
The State’s DMV Director, Steve Gordon, said that he hoped “Tesla will find a way to get these misleading statements corrected.” However, Tesla responded to the story on Tuesday, stating that this was a “consumer protection” order for the company using the term Autopilot.
It said “not one single customer came forward to say there’s a problem.” It added that “sales in California will continue uninterrupted.”
This was a “consumer protection” order about the use of the term “Autopilot” in a case where not one single customer came forward to say there’s a problem.
Sales in California will continue uninterrupted.

Tesla has used the terms Autopilot and Full Self-Driving for years, but has added the term “(Supervised)” to the end of the FSD suite, hoping to remedy some of the potential issues that regulators in various areas might have with the labeling of the program.
It might not be too long before Tesla stops catching flak for using the Full Self-Driving name to describe its platform.
Tesla Robotaxi goes driverless as Musk confirms Safety Monitor removal testing
The Robotaxi suite has continued to improve, and this week, vehicles were spotted in Austin without any occupants. CEO Elon Musk would later confirm that Tesla had started testing driverless rides in Austin, hoping to launch rides without any supervision by the end of the year.
Tesla stock (NASDAQ: TSLA) closed at an all-time high on Tuesday, jumping over 3 percent during the day and finishing at $489.88.
The price beats the previous record close, which was $479.86.
Shares have had a crazy year, dipping more than 40 percent from the start of the year. The stock then started to recover once again around late April, when its price started to climb back up from the low $200 level.
This week, Tesla started to climb toward its highest levels ever, as it was revealed on Sunday that the company was testing driverless Robotaxis in Austin. The spike in value pushed the company’s valuation to $1.63 trillion.
Tesla Robotaxi goes driverless as Musk confirms Safety Monitor removal testing
It is the seventh-most valuable company on the market currently, trailing Nvidia, Apple, Alphabet (Google), Microsoft, Amazon, and Meta.
Shares closed up $14.57 today, up over 3 percent.
The stock has gone through a lot this year, as previously mentioned. Shares tumbled in Q1 due to CEO Elon Musk’s involvement with the Department of Government Efficiency (DOGE), which pulled his attention away from his companies and left a major overhang on their valuations.
However, things started to rebound halfway through the year, and as the government started to phase out the $7,500 tax credit, demand spiked as consumers tried to take advantage of it.
Q3 deliveries were the highest in company history, and Tesla responded to the loss of the tax credit with the launch of the Model 3 and Model Y Standard.
Additionally, analysts have announced high expectations this week for the company on Wall Street as Robotaxi continues to be the focus. With autonomy within Tesla’s sights, things are moving in the direction of Robotaxi being a major catalyst for growth on the Street in the coming year.
