Tesla’s new Media Control Unit for the Model S and Model X was recently put through a controlled test against the company’s old MCU. The video, recently uploaded by My Tesla Adventure on YouTube, showed that the new MCU was around twice as fast as the NVIDIA Tegra-3-powered units on Tesla’s older vehicles.

The controlled test covered four different features of the media control unit — destination navigation, vector map responsiveness, dash navigation button speed, and of course, the built-in web browser. Both vehicles were hooked up to the same Wi-Fi network, putting the electric cars on even ground.

The first test involved destination navigation, with the Tesla enthusiast instructing both cars to navigate to Tesla’s delivery center in Marina Del Rey, CA. The new MCU was able to calculate the route, suggest charging stops, and set the destination in 9.27 seconds. The older MCU unit displayed the same data in 20.73 seconds.

Zooming in and out of the electric cars’ vector maps was roughly twice as fast in the newer MCU, with the newer unit being able to zoom out to the US map and zoom in back to the vehicle’s location in 27.97 seconds. The older MCU took 54.59 seconds to accomplish this task. My Tesla Adventure, however, noted that the true difference-maker with the old and new MCUs was the responsiveness of the updated media control unit.

“When testing the manual map navigation with vectoring, I noticed that it was hard to navigate with the old MCU because of the delay in response times from my finger inputs and the responsiveness of the screen. So it resulted in me kind of sliding all over the place on the map and going to places I didn’t intend to go.”

The difference in the old and new MCU’s speed when navigating through the dash buttons was less prominent. As could be seen in the video, the new unit was slightly faster than the new MCU, but the older media control unit was still fast and responsive. The cars’ web browser, however, showed the biggest difference in performance and speed. Loading Tesla.com from Google.com took the new MCU 12.10 seconds. The older media control unit, however, took a whopping 48.32 seconds before it was able to load the official Tesla website.

As we previously noted in a report, a Tesla spokesperson has confirmed with Teslarati that hardware changes to the onboard displays of Model S and Model X vehicles have been initiated by the company as part of Tesla’s continuous effort to introduce hardware and software improvements to its fleet over time. 

The improvements to the car’s internet browser are quite noteworthy, especially since it has been teased by Elon Musk in the past. Back in December, Musk admitted that the Model S and X’s browsers were indeed “terrible,” and assured the Tesla community that “major browser upgrades” would be rolled out to the company’s fleet of vehicles in a few months.

Tesla saves its passengers again – This time after a 300-foot cliff fall in Malibu

A Tesla Model 3 fell 300 feet off a Malibu cliff and both passengers survived.

Published

A Tesla Model 3 plunged roughly 300 feet off a cliff on Mulholland Highway in Malibu on Friday morning, May 29, 2026, and both occupants survived. The crash was reported at approximately 7:30 a.m. near the 2500 block of Mulholland Highway, triggering a multi-agency rescue operation involving Malibu Search and Rescue, the Los Angeles County Fire Department, the California Highway Patrol, and McCormick Ambulance.

When first responders arrived, the male driver was outside the vehicle shouting for help while the female passenger remained pinned inside the Tesla. Rescue crews rappelled down the cliffside on ropes to reach the wreckage. A flight medic was lowered by helicopter to begin treating both victims, and the driver was hoisted up to the roadway before crews used the Jaws of Life to free the trapped passenger. Both were airlifted to a local trauma center with moderate injuries despite a remarkable result for a fall that steep.

The outcome is not surprising, considering Model 3 earned an overall 5-star rating from NHTSA in every category and sub-category, and recorded the lowest probability of injury of any car ever evaluated by the U.S. New Car Assessment Program. The absence of a traditional engine in the front of the vehicle creates a longer crumple zone that absorbs impact energy before it reaches occupants, and the battery pack running along the floor gives the car an unusually low center of gravity that reinforces structural rigidity.

This is not the first time a Tesla has kept passengers alive after going off a cliff. A Tesla Model Y carrying a family of four survived a plunge off a cliff at Devil’s Slide near San Francisco in January 2023, with two adults and two children walking away from a 250-foot fall. That incident drew widespread attention to how the structural integrity of Tesla’s electric platform performs in extreme crash scenarios that most vehicles would not survive.

Tesla Full Self-Driving (Supervised) has taken yet another significant step forward in Europe. On May 29, Estonia became the third European Union country to approve the advanced driver-assistance technology, following approvals in the Netherlands and Lithuania.

Tesla Europe announced the news on X, confirming the expansion has continued across the continent that, at one time, seemed to be taking its sweet old time giving any approval to the FSD suite.

Estonia’s Transport Administration (Transpordiamet) granted the approval by recognizing the type certification issued by the Dutch vehicle authority RDW. This mutual recognition mechanism, enabled by EU regulations, allows other member states to fast-track deployment without repeating extensive local testing.

The Estonian authority noted that Tesla’s FSD had undergone rigorous evaluation on European roads for approximately 18 months before the initial Dutch approval in April 2026.

FSD Supervised remains classified as a Level 2 advanced driver-assistance system (ADAS). Drivers must maintain full attention, keep their hands on the wheel, and stay ready to intervene at any moment.

The system assists with tasks such as automatic lane changes, navigation through city streets, and responding to traffic objects, but it does not constitute full autonomy. Estonian officials emphasized this distinction, underscoring that safety responsibility lies entirely with the driver.

The rapid progression across the Baltic region highlights Tesla’s strategic approach to European expansion. The Netherlands provided the foundational type approval in April, unlocking doors for neighboring countries.

Lithuania followed swiftly in mid-May, with rollout beginning shortly thereafter. Estonia’s decision, coming just days later, demonstrates how smaller, digitally progressive nations are accelerating adoption.

Tesla owners in Estonia can expect an over-the-air software update in the coming weeks, bringing the latest FSD capabilities to compatible vehicles

This expansion builds on Tesla’s global momentum. FSD Supervised is now available in 11 countries worldwide, including the United States, Canada, Australia, and South Korea. In Europe, the approvals signal growing regulatory confidence in Tesla’s vision-based AI approach, which relies on cameras and neural networks rather than lidar or radar-heavy alternatives used by some competitors.

For Tesla, these European milestones are more than symbolic. They validate years of data collection and software iteration while opening new revenue streams through FSD subscriptions and purchases.

As the company continues refining its AI models with real-world miles from diverse driving environments, including Estonia’s variable winter conditions, the dataset grows richer, potentially benefiting global users.

Elon Musk has firmly denied recent media reports suggesting that SpaceX has reduced its target valuation for an upcoming initial public offering.

The denial came directly from the SpaceX and Tesla frontman on his social media platform X, where he responded with a single word, “False,” to a post from ZeroHedge that cited Bloomberg sources.

This swift rebuttal underscores Musk’s ongoing effort to manage speculation surrounding one of the most anticipated market debuts in recent history.

According to the disputed reports, SpaceX had lowered its IPO valuation goal to at least $1.8 trillion from previous ambitions exceeding $2 trillion.

The claims emerged amid growing anticipation for the company’s confidential S-1 filing, which positions it for a potential public listing as early as June.

Some had pointed to strong revenue growth, particularly from the Starlink satellite internet service, which contributed heavily to the firm’s 2025 figures of $18.7 billion. Yet challenges persist in other areas, including substantial investments and losses tied to ambitious projects like Starship development and artificial intelligence initiatives, which plan to make life multiplanetary eventually.

Musk’s response highlights a pattern in which he actively counters what he views as inaccurate portrayals of his companies’ trajectories.

SpaceX, already valued privately at extraordinary levels, stands as a cornerstone of Musk’s empire alongside Tesla and xAI. The entrepreneur has long emphasized the transformative potential of reusable rockets and global broadband access, factors that fuel investor enthusiasm despite operational hurdles.

By rejecting the valuation downgrade narrative, Musk signals confidence in SpaceX’s fundamentals and its readiness for public markets on terms favorable to its long-term vision. People have been waiting a very long time to invest in SpaceX, and the valuation, as well as the introductory share price, is not going to need adjusting.

They’ll have plenty of suitors.

This episode reflects broader dynamics in the technology sector, where rumors often swirl around high-profile entities. Musk’s direct engagement with media narratives serves to maintain transparency and control the narrative around his ventures.

As SpaceX prepares for greater scrutiny in public markets, the founder’s denial reinforces optimism about its prospects. Supporters argue that the company’s innovative edge positions it for enduring success, far beyond short-term valuation debates. With the denial now public, attention turns to forthcoming regulatory filings that could provide clearer insights into SpaceX’s strategy and financial health.

The coming weeks promise to reveal more about how SpaceX will transition into a publicly traded powerhouse.
