Tesla’s ‘Bioweapon Defense Mode’ is proving invaluable to owners affected by CA wildfires

Published

on

When Elon Musk initially talked about the Model X’s “Bioweapon Defense Mode,” the company’s skeptics dismissed the feature as a simple gimmick. For owners of the company’s electric cars currently affected by the raging wildfires in CA, though, Bioweapon Defense Mode has become a welcome blessing, allowing them and their passengers to breathe clean air despite the worsening air quality outside.

California is currently facing its most destructive fires in the state’s history. As of Friday, the northern California city of Paradise has already been lost to the blaze. More than 6,700 structures have also burned to the ground in northern CA’s Camp Fire on Thursday and Friday. At least nine people have perished against the onslaught of expanding wildfire, and more than 250,000 people have been forced out of their homes as well. Despite authorities’ best efforts, Los Angeles fire officials noted on Friday afternoon that the blaze remains “zero contained.”

Reports from members of the Tesla community living in areas affected by the wildfires have noted that their vehicle’s Bioweapon Defense Mode has effectively maintained the air quality inside their cars. One such owner, Andrei Bulu, even posted a couple of pictures on social media showing the air readings from inside and outside his Model X as he was driving through the Bay Area, which is being affected by the fire in Paradise. As could be seen in the Model X owner’s post, the air quality readings improve dramatically when his electric SUV’s windows were up and Bioweapon Defense Mode was enabled.

Other Tesla owners driving in areas currently affected by the CA fires have shared similar experiences as well.

Bioweapon Defense Mode incited a notable amount of lighthearted laughter from the audience when Elon Musk announced the feature for the Model X. During the vehicle’s unveiling, Musk candidly stated that the function is possible due to the Model X’s incredibly large HEPA filter, which is around ten times as large as those of a regular fossil fuel-powered car. Tesla noted that Bioweapon Defense Mode, which was later added on the Model S, 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.”

In true Tesla fashion, the company’s skeptics were notably unimpressed with the feature, with many claiming that Bioweapon Defense Mode was but a marketing statement. Tesla later debunked these claims by holding a controlled test of a Model X 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). Within two minutes, the Model X’s HEPA filtration system had scrubbed the air inside the all-electric SUV, and in the following minutes, even the air around the vehicle started getting cleaner.

While Tesla’s electric car owners are able to breathe clean air despite the CA wildfires due to their vehicles’ Bioweapon Defense Mode, Elon Musk has stated that the company’s electric cars might prove helpful in moving people away from areas compromised by the blaze. An email Musk sent to employees reportedly even encouraged Tesla workers to provide assistance to the ongoing rescue efforts if they can, and not worry about compensation.

Over the years, Tesla has developed a reputation for helping out when it is able. Amidst the onslaught of this year’s hurricanes, Tesla provided temporary free unlimited Supercharging and a range upgrade to owners of Model S 40, 60, and 70 vehicles, enabling them to leave hurricane-affected areas. Elon Musk, for his part, also continues to provide some humanitarian aid as well. Just last month, it was revealed that Musk had been helping Flint, MI by giving the necessary funds to install water filtration systems to the district’s school buildings.

Tesla Sweden’s port deal sparks political clash in Trelleborg

The extension of Tesla’s lease has drawn criticism from the local Social Democratic opposition.

Tesla Sweden’s lease agreement at the Port of Trelleborg has triggered a political dispute, with local leaders divided over whether the municipally owned port should continue renting space to the electric vehicle maker amidst its ongoing conflict with the IF Metall union.

Tesla Sweden’s recently extended contract with the Port of Trelleborg has triggered calls for greater political oversight of future agreements.

Tesla has used the Port of Trelleborg to import vehicles into Sweden amid a blockade by the Transport Workers’ Union, as noted in a report from Dagens Arbete (DA). By routing cars via trucks on passenger ferries, the company has maintained deliveries despite the labor dispute. Vehicles have also been stored and prepared in facilities leased from the municipal port company.

The extension of Tesla’s lease has drawn criticism from the local Social Democratic opposition. Initially, the Port of Trelleborg hinted that it would not enter into new agreements with Tesla, but it eventually opted to renew its existing contract with the EV maker anyway.

Lennart Höckert, an opposition councilor, described the port’s decision as a “betrayal of the Swedish model,” arguing that a municipally owned entity should not appear to side with one party in an active labor dispute.

“If you want to protect the Swedish model, you shouldn’t get involved in a conflict and help one of the parties. When you as a company do this, it means that you are actually taking a position and making things worse in an already ongoing conflict,” Höckert said. 

He added that the party now wants politicians to review and approve future rental agreements involving municipal properties at the port.

The proposal has been sharply criticized by Mathias Andersson of the Sweden Democrats, who chairs the municipal board. In comments to local media, Andersson described the Social Democrats’ approach as “Kim Jong Un-style,” arguing that political leaders should not micromanage a company governed by its own board.

“I believe that the port should be run like any other business,” Andersson said. He also noted that operational decisions fall under the authority of the Port of Trelleborg’s board instead of elected officials.

Elon Musk’s X sees outage on Monday as users report issues

Monday’s outage follows a similar issue that befell the social media platform in mid-January.

X experienced an outage on Monday morning, with tens of thousands of users reporting that the platform failed to load across both desktop and mobile. The disruption began around 8:02 a.m. ET, as per Downdetector data, and quickly escalated in the U.S. and U.K.

Monday’s outage follows a similar issue that befell the social media platform in mid-January.

Shortly after 8 a.m. ET, Downdetector showed a sharp rise in incident reports. At one point, U.S. complaints exceeded 40,000, while U.K. reports climbed past 6,000. Earlier in the outage, filings had already crossed 11,000 in the U.S. and 3,300 in the U.K., as noted in a TechRadar report. X users in other locations, such as the Philippines and Costa Rica, also reported similar issues.

Users attempting to access X were met with a “something went wrong” message. Feeds did not refresh, posts failed to appear, and both the social media platform’s app and web versions appeared affected by the issue. The outage struck during peak weekday usage, amplifying its visibility across regions worldwide.

X has not issued an official explanation for the latest outage or confirmed what caused the service disruption. The scale of complaints drew comparisons to the platform’s major outage in November 2025, which resulted in users being met with “Internal server error / Error code 500” messages, as well as Cloudflare-related error notices.

The incident also comes just weeks after X experienced a similar downtime in mid-January. That outage seemed more notable, however, with more than 100,000 users reporting issues with the social media platform on Downdetector.

Newly released bidding documents have shed light on how Elon Musk’s Boring Company plans to connect Universal Orlando Resort’s north campus to Universal Epic Universe. 

The materials outline staffing, construction timelines, tunnel configuration, and operational details that were not previously public about the planned Loop system.

The Shingle Creek Transit & Utility Community Development District voted Feb. 11 to begin contract negotiations with The Boring Company after ranking it the top bidder for the Universal Orlando transport project. Now, evaluation documents obtained by local news media reveal how the company intends to execute the project, according to Attraction Insight.

The proposal describes a twin-tunnel configuration, with one tunnel in each direction. It also noted that permitting, design, and construction could take roughly a year and a half once approvals are secured. The company indicated it could deploy multiple tunnel boring machines and install temporary support infrastructure, including muck storage pits and stormwater systems, during construction.

Bid documents list eight internal specialists assigned to the project, including tunnel engineers, structural engineers, and tunnel boring machine experts. Six subcontractors would handle fire protection, communications, soil treatment, and concrete work.

The company stated it “has the necessary internally produced tunneling equipment and personnel immediately available to complete this project for the district as quickly as permits and approvals can be obtained.”

Operationally, the system would mirror the company’s Las Vegas Loop model, using Tesla vehicles to provide point-to-point transport rather than fixed-route buses. The proposal frames the concept as “on-demand, express transportation,” with vehicles dispatched as needed and capacity adjustable in real time.

Stations could be built underground or above ground with ramp access into tunnels. The documents also referenced potential future integration of a configurable Robovan for passengers and cargo, though capacity projections for the Orlando tunnels have not yet been disclosed.

The proposal states that the Loop can integrate “easily into environmentally sensitive areas,” but it does not provide detailed mitigation plans for Central Florida’s high water table and limestone geology, which is susceptible to sinkholes. The company has stated that it intends to hire an Orlando-based geotechnical firm to evaluate soil conditions.
