Tesla shows off its super-effective HEPA filter and Bioweapon Defense Mode in crazy new test
Tesla released a new video to its YouTube channel today to show off its super-effective HEPA filter, which when combined with Bioweapon Defense Mode, keeps nearly all traces of pollution and particulate matter out of the cabin.
Tesla has used the HEPA filter and Biodefense Mode in the Model Y since 2020. It has been installed in other vehicles, namely, the Model X and Model S, for many years. In the new test video, the Model Y goes up against another vehicle that does not have a HEPA-grade filter or Bioweapon Defense Mode. The purpose of the test was to show the effectiveness of the HEPA filter and Bioweapon mode, especially as Tesla claims it takes “up to 99.97% or greater” of particulate matter out of the air, providing safe and pollution-free air for the cabin’s occupants.
Nearly six years ago, Tesla performed basically the same test with a Model X. The all-electric SUV was placed inside a large bubble that was contaminated with extreme levels of pollution. The Model X safely and effectively removed so much of the particulate matter and pollution from the air, that levels were so low they were undetectable by the instruments used.
In the new experiment, a series of smoke bombs were set off inside the bubble to give a more visual representation of the effectiveness of the HEPA filter and Bioweapon Defense Mode. After several moments in the car, the Model Y’s cabin remained smoke-free. The cabin was able to be occupied by a Tesla employee. The other car, which had a camera installed inside just as the Model Y did, was filling with smoke quickly.
The post-test analysis of the HEPA filter provided valuable feedback. Not only was the filterable to capture nearly all of the particulate matter, but the red smoke was able to be spotted on the HEPA-grade filter.

The HEPA filter is inspired by air filtration systems used in hospitals, clean rooms, and the aerospace industry and can prevent smoke, bacteria, and pollen from entering the cabin. In today’s world, this is an underrated feature, especially as any air from the outside world becomes what passengers breathe in a car. Without a HEPA filter and Bioweapon Defense Mode, there is pollution entering the cabin, which becomes the air that you and your passengers will breathe.

Elon Musk: Tesla autonomous driving might spread faster than any tech
The CEO noted that “hardware foundations have been laid for such a long time.”
Elon Musk has shared one of his most optimistic forecasts for Tesla’s self-driving rollout yet. As per the CEO, Tesla’s self-driving system could see the fastest technological adoption in history, thanks to the fleet’s capability to gain autonomous capabilities through a software update.
The CEO shared his forecast in a post on social media platform X.
Tesla’s aims to scale autonomy
Musk’s comment came as a response to industry watcher Sawyer Merritt, who posted a comparison between the geofence of Tesla’s Robotaxi network and Waymo’s service area. As can be seen in the graphic, Tesla’s Austin geofence has gotten noticeably larger compared to Waymo’s service area.
In his response, Musk stated that “Tesla autonomous driving might spread faster than any technology ever.” He also stated that “hardware foundations have been laid for such a long time,” as a software update could unlock full autonomy “for millions of pre-existing cars in a short period of time.”
Musk’s comment bodes well for Tesla’s Robotaxi ambitions, which seem to be finally in reach with the deployment of Unsupervised FSD in vehicle factories, as well as Austin and the Bay Area. For now, however, Tesla’s Austin Robotaxis and Bay Area ride-hailing vehicles are still operated with a safety monitor in the driver’s seat.
Tesla’s latest Austin expansion
Tesla recently expanded its Austin Robotaxi service area this week to 243 square miles, its largest yet and nearly triple the coverage from two months ago. The move outpaces Waymo’s local service footprint, which remains at around 90 square miles.
The expansion marks Tesla’s second major Austin update since August and emphasizes its push to dominate the autonomous ride-hailing landscape. With both Tesla and Waymo racing to prove scale and reliability, Musk’s confidence suggests the real contest may be about who can move fastest once the tech flips on across Tesla’s fleet. Once that happens, Tesla would effectively be able to win the self-driving race.

Tesla sends clear message to Waymo with latest Austin Robotaxi move
It is the first expansion Tesla has made in Austin since the one on August 26. The company still operates in the Bay Area of California as well, referring to that program specifically as a “ride-hailing service.”
Tesla has sent a clear message to Waymo with its latest move to its Robotaxi program in Austin, Texas.
Tesla and Waymo are the two true leaders in autonomous ride-hailing to an extent. Tesla has what many believe is a lot of potential due to its prowess with the Supervised Full Self-Driving suite. It is also operating a driverless Robotaxi service in Austin with a “Safety Monitor” that sits in the passenger’s seat.
Tesla explains why Robotaxis now have safety monitors in the driver’s seat
The two companies have been competing heavily in the market since they both launched driverless ride-hailing services in Austin this year: Waymo’s in March and Tesla’s in June.
One of the main drivers in the competition between the two is service area size, or the geofence in which the cars will operate without a driver. In August, the two were tied with a service area of about 90 square miles (233.099 sq. km).
Tesla then expanded to about 170 square miles (440.298 sq. km) on August 26, dwarfing Waymo’s service area and expanding to freeways. Tesla’s freeway operation of the Robotaxi suite requires the Safety Monitor to be in the driver’s seat for safety reasons.
On Tuesday evening, Tesla made another move that sent a clear message to Waymo, as it expanded once again, this time to 243 square miles (629.367 sq. km).
This is according to Robotracker:

It is the first expansion Tesla has made in Austin since the one on August 26. The company still operates in the Bay Area of California as well, referring to that program specifically as a “ride-hailing service.”
Yesterday, it expanded that service to the San Jose Mineta International Airport, something it has been working on for several months.
Waymo has its own set of distinct advantages over Tesla as well, as it operates in more cities and states than the EV maker. Waymo currently has its autonomous vehicle services in Phoenix, Arizona, San Francisco, Los Angeles, Austin, and Atlanta, Georgia.
Tesla plans to have half of the U.S. population with access to the Robotaxi platform by the end of the year.

Tesla exec reveals shock development with Cybercab
“If we have to have a steering wheel, it can have a steering wheel and pedals.”
Tesla is planning to launch the Cybercab in the second quarter of next year, and it is designed to be fully autonomous, so much so that the company is planning to build it without a steering wheel or pedals.
However, a Tesla executive said today that the company could ditch that idea altogether in what would be a major shift from the plans the company, and especially its CEO Elon Musk, have announced for the Cybercab.
Earlier today, Robyn Denholm, the company’s Chair for the Board of Directors, revealed that Tesla would potentially switch up its plans for the Cybercab based on potential regulatory requirements.

Currently, even autonomous vehicles that operate for companies like Tesla and Waymo are required to have steering wheels and pedals. From a regulatory perspective, this could halt the plans Tesla has for Cybercab.
Denholm said in an interview with Bloomberg:
“If we have to have a steering wheel, it can have a steering wheel and pedals.”
Interestingly, Musk and Tesla have not veered away from the idea that the vehicle will be without these operational must-haves.
Since the vehicle was revealed last October at the We, Robot event in Los Angeles, Tesla has maintained that the car would be built without a steering wheel or pedals, and would equip two seats, which is what is statistically most popular in ride-sharing, as the vast majority of rides have only one or two passengers.
Musk doubled down on the plans for Cybercab as recently as last week, when he said:
“That’s really a vehicle that’s optimized for full autonomy. It, in fact, does not have a steering wheel or pedals and is really an enduring optimization on minimizing cost per mile for fully considered cost per mile of operation. For our other vehicles, they still have a little bit of the horse carriage thing going on where, obviously, if you’ve got steering wheels and pedals and you’re designing a car that people might want to go very direct past acceleration and tight cornering, like high-performance cars, then you’re going to design a different car than one that is optimized for a comfortable ride and doesn’t expect to go past sort of 85 or 90 miles an hour.”
Cybercab is fully conceptualized as a vehicle that has zero need for pedals or a steering wheel because it is aimed toward being fully reliant on a Level 5 autonomous platform.
Tesla is ramping its hiring for Cybercab vehicle manufacturing roles
Regulators could get in the way of this, however, and although the car could drive itself and be a great solution for ride-hailing, it might need to have these controls to hit the road in the future.
