Tesla’s ‘Bioweapon Defense Mode’ is proving invaluable once more amid CA’s wildfires
Tesla Model S and Model X owners affected by the ongoing wildfires in CA are thanking the electric car maker once more for their vehicles’ Bioweapon Defense Mode, which allows passengers to breathe clean air inside the cabin despite hazardous air conditions outside.
The state of CA is currently experiencing several blazes. In Southern CA alone, authorities from the Riverside County Sheriff’s Department have confirmed that the Sandalwood Fire in Calimesa has taken the lives of two individuals, an 89-year-old woman in a mobile home and another person that is yet to be identified.
The Sandalwood Fire, which has so far burned 820 acres and was at least 25% contained as of Saturday, is only one of several blazes in the state. The Saddleridge Fire, currently the largest in the state, has burned more than 7,500 acres and destroyed around 31 homes. Amidst these blazes, the South Coast Air Quality Management District has urged residents to protect themselves from heavy smoke and dangerous air conditions.
It is these dangerous air conditions that are being addressed by Tesla’s Bioweapon Defense Mode for the Model S and X, and some electric car owners have taken to social media to share their experiences with the feature. A Tesla Model X owner who goes by the handle @BLKMDL3 on Twitter, for one, mentioned that Bioweapon Defense Mode was a “lifesaver” as he and his passengers were traveling in Los Angeles.
“Thank you Elon Musk and Tesla for helping us with breathing issues during the fires today in Los Angeles due to bad air quality. Bioweapon defense mode is a life saver,” the Tesla owner wrote.
Fellow Tesla enthusiast and r/TeslaMotors subreddit member u/cherrycolasoda shared a similar experience that was briefly captured on film. The Tesla enthusiast mentioned that Bioweapon Defense Mode significantly helped with the air quality in the cabin as they passed through an area that was practically surrounded by fires. The vehicle’s Autopilot system reportedly functioned normally, following lane lines without any difficulties despite the conditions on the road.
Bioweapon Defense Mode is made possible by the extremely large HEPA filter in the Model X (later equipped on the Model S as well). Tesla notes that Bioweapon Defense Mode is “100 times more effective than premium automotive filters, removing at least 99.97% of fine particulate matter and gaseous pollutants, as well as bacteria, viruses, pollen, and mold spores.”
These statements were met with a notable degree of skepticism and dismissal from critics, though Tesla later demonstrated Bioweapon Defense Mode’s capabilities by holding a test on a Model X. During the demonstration, the company placed the all-electric SUV inside a bubble contaminated with extreme levels of pollution (1,000 µg/m3 of PM2.5 vs. the EPA’s “good” air quality index limit of 12 µg/m3). Bioweapon Defense Mode effectively scrubbed the air inside the Model X’s cabin in 2 minutes, and over the next few minutes, the vehicle started cleaning the air around the SUV as well.

Tesla gets its latest short from Michael Burry: ‘Happy it jumped back to this level’
Tesla short seller Michael Burry, the subject of the film “The Big Short,” where he was portrayed by Steve Carell, has revealed he has opened a new bet against the stock.
In a new update to his Substack newsletter in a post titled “Trading Post June 30, 2026,” Burry revealed a new set of bets against Tesla, Caterpillar, NVIDIA, Applied Materials Inc., and the iShares Semiconductor ETF.
In regard to Tesla, Burry wrote:
“And finally I shorted Tesla at 416.22. Happy it jumped back to this level.”
This means Burry likely opened his new short position after the company’s recent rally on Wall Street, which saw Tesla shares sink in mid-May, only to recover to well over the $400 mark. Currently, shares trade at around $427.
The company saw a big Tuesday as shares climbed considerably, over 10 percent. The size of the Tesla short was not provided, nor did Burry give any information on the position’s structure, the number of shares, dollar value, or whether options were used in the short.
The Tesla and SpaceX merger everyone is talking about is quietly building
Over the years, Burry has been one of the more vocal critics of Tesla, calling its share price “media inflated,” and saying it was “ridiculously overvalued” as recently as December.
The company has largely transitioned away from being known as an automotive company and instead is much more widely regarded as an AI play, mostly due to its Full Self-Driving efforts, Optimus robot development, and data collection related to both.
This has not pulled those skeptics away from being vocal about their distaste for how Tesla is valued, but there’s no denying that the company is a global force in many things, including sustainable energy, automotive, and AI.
Wedbush Securities is initiating stock coverage on SpaceX (NASDAQ: SPCX), marking the first comments on the company since it went public several weeks ago. Wedbush and its analyst handling coverage, Dan Ives, are widely bullish on fellow Musk company Tesla (NASDAQ: TSLA).
Ives wrote his first note initiating coverage of SpaceX shares on Wednesday with a $190 price target and an ‘Outperform’ rating. The firm believes the company is well positioned off of its IPO because of its wide array of projects, including AI compute power and infrastructure, connectivity projects, and launches.
“We view SpaceX as one of the most differentiated assets within the tech market with a strong footprint across its three core markets, with Starlink driving success with connectivity,” Ives wrote, “Starship launches leading to a demand flywheel and increasing deal flow for its Colossus clusters.”

Wedbush leans heavily on Starlink, which they say is the “profitability driver given the strength of its recurring revenue base of ~12 million subscribers as of June 5th.” Ives believes Starlink is still in the “early innings” of penetrating the global telecommunications and broadband market, as it only holds less than a 1 percent share. However, this number is sure to increase over time.
It also highlights the importance of Starship, which it says is an “essential layer” of SpaceX’s overall success. SpaceX developing and displaying the ability to reuse rockets is a major cost and reliability advantage “as it reduces the necessary hardware launch costs while generating a feedback loop for future flights to improve their launch flight rate without accelerating capex spend.”
Finally, SpaceX’s recent AI/Compute projects are also very elementary, Ives writes. It is worth mentioning Wedbush said its $190 price target is derived from a valuation forecast that sees the company yielding roughly $2.48 trillion of implied enterprise value.
There are also some factors that Wedbush did not take into account with its initial coverage. The firm wrote in the note:
“We note that there is optional value coming from Starship’s accelerating scale towards sub-$200/kg unit economics, orbital data centers, and enterprise AI monetization as these factors could drive meaningful upside but these face major hurdles, so we do not take that into account with our valuation.”
SpaceX shares are down just over 2 percent today, trading at around $167 at the time of publication.
Tesla has expanded the footprint of a massive safety feature worldwide with a recent Software Update labeled as 2026.20.6. The expansion of the “Blind Spot Warning While Parked” feature represents the more widespread availability of the feature, which aims to prevent “dooring.”
Dooring is when a driver or passenger opens a car door into the path of an oncoming road user, usually a cyclist or motorcyclist. It is among the most common types of cycling accidents, the League of American Bicyclists says.
For this reason, Tesla created a feature that warns occupants not to open the door because an object is approaching. The feature will sound a chime, and it will also delay the opening of the door to prevent an incident.
The release notes state (via Not a Tesla App):
“If you attempt to open a door while an approaching object is detected in your blind spot (for example, a bicyclist approaching from behind) a chime sounds, and your door will not open upon initial button press. Wait a short time and press the button a second time to override the warning.”
Tesla initially rolled out this feature back in 2024 with the Model 3 “Highland.” However, it remained with the Model 3 exclusively for over a year; that was until Tesla added it to the Cybertruck this past Spring.
Now, it is making its way to the new Model Y, 2021 and newer Model S, and 2021 or newer Model X.
The prevention of dooring incidents could eliminate many injuries to cyclists, especially in an urban setting. Dooring accounts for 10-20 percent of bike-related crashes in major cities, and over 17,000 dooring-related incidents were treated in the U.S. over the course of a decade. These usually involve fractures, contusions, and head trauma.
