The HEPA filter in Bioweapon Defense Mode is inspired by air filtration systems used in hospitals, clean rooms, and the aerospace industry. When activated, the climate control system pulls in outside air and filters it through the HEPA filter and secondary filtration system. This process effectively removes harmful particles and contaminants from the air.

In addition to the filtration process, Bioweapon Defense Mode creates a positive-pressure environment inside the cabin. This feature, borrowed from hospital settings, prevents outside air from leaking into the vehicle. The result is an air-tight cabin that continuously filters and circulates clean air to protect passengers from pollutants, pathogens, and allergens.

Tesla has conducted experiments (video below) to demonstrate the effectiveness of its HEPA filtration system and Bioweapon Defense Mode. In one such experiment, a Tesla Model Y and a BMW X3 were parked inside a giant bubble, and smoke bombs were detonated. The Model Y had Bioweapon Defense Mode activated, while the BMW X3 relied on its standard filtration system.

During the experiment, a Tesla employee sat in the driver's seat of the Model Y to showcase the company's confidence in its product. The video showed that the cabin of the Model Y remained free from red smoke, while the interior of the BMW X3 was invaded by it. After the experiment, Model Y's activated carbon filters and HEPA filters were removed, revealing that they had captured a significant amount of red dust.

The filtration system is active whenever climate control is pulling in outside air. In extreme conditions, users can activate Bioweapon Defense Mode, which positively pressurizes the vehicle’s cabin, preventing pollutants from leaking. All air is filtered through the HEPA and gas media filters in this mode.

New map icons

Tesla’s latest software update, version 2023.44.30.4. improves Tesla maps by integrating icons for traffic lights, stop signs and more directly onto the map.

The new icons help drivers be more aware of what their route looks like and what’s coming up next, potentially warning them of hidden stop signs or speed cameras.

All Icons And Their Meanings

There’s a lot more to this feature than just displaying traffic lights and stop signs. Tesla is displaying a large array of various conditions. According to Greentheonly, Tesla is displaying up to 11 different icons on its maps. The various icons you may see include:

Average Speed Camera - Instead of recording your speed at a specific moment in time, these systems use two or more cameras to determine your average speed between two points. If your average speed is higher than the speed limit, then you were speeding and may be ticketed.

Caution Lights - It’s not clear what this icon represents, but it may be used to identify flashing yellow lights

Construction - An icon that alerts you of recent construction areas

Danger Zone - A danger zone is defined by local law and provided by the local government. It’s only available in select regions.

Fixed Speed Camera - Fixed speed cameras capture a vehicle’s speed at a specific location.

Mobile Speed Camera - A mobile speed camera is when a speed camera is mounted to a vehicle instead of being a part of the city structure.

Police - An icon that may display the location of police or police departments

Red Light Speed Camera - A red light speed camera is usually mounted on traffic lights or near the intersection. The camera aims to capture the license plate of any vehicles crossing the intersection if the light has turned red.

Speed Camera (generic) - This appears to be a generic icon for speed cameras on the map. It’s possibly used if Tesla doesn’t know the type of speed camera at the location.

Stop Sign - A traditional stop sign. It’d be a great addition if Tesla could include whether the intersection has a stop sign in all directions or if the crossing street doesn’t stop.

Traffic Light - A traffic light with more than one light

The actual icons available and displayed are dependent on your region. Not all icons are available in all regions.

Data and Requirements

Unfortunately, this feature is not available to everyone. It’s limited to specific regions where the data is available (check out our release notes to see if it’s available in your region). However, it also requires owners to subscribe to Tesla’s Premium Connectivity service at $10/month in the US. Contrary to some other information going around, this feature does not require the latest map data.

Although it does require drivers to have Online Routing enabled to view this new data. To activate or see if you have online routing enabled, you can go to Controls > Navigation and confirm Online Routing is turned on.

While Tesla can determine traffic lights and stop signs using machine learning, they’re likely buying this additional data through an existing provider, which is why they’re requiring Premium Connectivity to use it.

The new icons are only displayed along your route and not on adjacent streets. This helps keep the display clean and easy to read, however, it could be useful to know where other traffic lights and stop signs are located when trying to find a faster route.

The icons on the map also disappear as you approach the item. So any traffic lights or speed cameras you recently passed are no longer displayed.

Tesla will also warn you about upcoming speed cameras above the next turn module.

Besides enhanced awareness of your surroundings and upcoming situations, these icons could also be used to aid in driving directions. Navigation system directions could sometimes be clearer and knowing where stop signs and traffic lights are could be an aid used in voice guidance. For example, instead of saying turn left onto Main St, it could use a traffic light as guidance and say turn left at the traffic light, or your destination will be on the right after the stop sign.

This is not something Tesla currently does, but this information leaves the door open for future enhancements.

Tesla Insights

The documents from European certifications, dated November 8, 2023, indicate the upcoming addition of "Adaptive Main Beam" headlights for the new Model 3, which is expected through an over-the-air software update. This revelation, initially shared by @eivissacopter (via DriveTeslaCanada), suggests that older models like the original Model 3 and current Model Y may not receive this update despite some of them having matrix headlights.

Update: It’s not completely clear whether the new Model 3 contains full matrix headlights like some other models or if they simply have an adaptive beam.

There's also no mention of Tesla's Model S and Model X getting support even though they now have matrix headlights as well.

European document reveals Tesla is adding matrix headlight support

The decision to initially limit this feature to the upgraded Model 3 is interesting. There’s no reason to believe this feature won’t eventually be added to other Tesla models that include matrix headlights, but the documents specifically mention the new Model 3 and its adaptive headlights. It should be noted that Tesla likes to test new software with a small segment of owners initially, however, the new Model 3 does feature new headlights. So it’s not clear if this is a software strategy or if there are changes in the new Model 3’s headlights that allow Tesla to finally enable them in Europe.

What Are Matrix Headlights?

Matrix headlights, also known as adaptive headlights, are an advanced automotive lighting technology designed to improve nighttime driving safety and visibility. They consist of multiple LED elements or individual light sources that can be controlled independently. This fine control allows the system to adapt the light distribution pattern based on factors such as traffic conditions, road curvature, and the presence of other vehicles.

Matrix headlights let your car turn on and off individual LEDs

The primary benefit of matrix headlights is their ability to selectively dim or deactivate specific LED elements to create "shadows" or dark areas in the beam pattern. This helps avoid dazzling oncoming drivers or those in front of the vehicle while maintaining optimal illumination of the road ahead. For example, when an oncoming vehicle is detected, the system will adjust the light pattern to prevent the high beams from shining directly into the other driver's eyes. The rest of the road, however, remains well-lit, ensuring clear visibility for the driver.

Varying Standards Globally

Globally, the rollout of these adaptive headlights will be subject to varying automotive regulations. Different countries have different standards for automotive lighting, and Tesla will need to navigate these as they introduce and expand the feature's availability. The European certification is crucial, as Europe often has more stringent automotive standards, potentially making it easier to introduce the feature in other markets afterward.

Customer Response

Adaptive headlights, a feature in luxury vehicles for some time, are now becoming more mainstream. This technology's primary benefit is safety. By dynamically adjusting the light beam according to steering input and its surroundings, these headlights significantly enhance night-time visibility and reduce the risk of accidents on curvy roads.

Customer response to this development will be critical. While some Tesla owners might be disappointed that their existing vehicles won't initially receive this feature, new buyers will likely find it a compelling addition. This dynamic could influence customer loyalty and brand perception, factors Tesla must manage carefully.
