Tesla Model 3 spotted with “pedestrian noise maker” ahead of NHTSA mandate
It looks like Tesla may have already begun getting its newer manufactured vehicles ready for compliance with an upcoming National Highway Traffic Safety Administration (NHTSA) requirement for electric and hybrid electric vehicles to make noise when traveling at slow speeds. In a video posted by Tesla community’s resident DIY expert, Erik, or otherwise known as DÆrik from his YouTube channel, the undercarriage panel of his Performance Model 3 has what appears to be a speaker grill – the front paneling is adorned with a series of holes in a hexagonal shape. Once the paneling is removed, three mounting points are revealed to be molded into the same area, hinting at a future device to come.
The video was made in response to inquiries about a photo of the Tesla’s undercarriage posted to Erik’s Instagram account where someone noted the series of holes in the plastic panel below the front bumper. Tesla’s parts catalog doesn’t currently show the grill cutout, but As Erik notes in the video, he found a Model S diagram three years ago showing a layout including a future noise maker labeled “Speaker Pedestrian Noise”.
We’ve reached out to Tesla for comment about the new “speaker grill” found in the underside of the Model 3 and will provide updates as we receive them.

Blind pedestrians rely heavily on auditory clues to anticipate traffic patterns and know a vehicle is near, and that means the quiet nature of electric and hybrid vehicles at low speeds may pose a greater danger to them than traditional internal combustion engine (ICE) vehicles. Bicyclists and other pedestrians also utilize usual car sounds as part of their personal safety awareness, so there’s a population of travelers that could be significantly impacted by the influx of EV/HEV vehicles on the roads. The potential danger has not gone unnoticed by those in charge of public safety.
This concern was elevated to the federal level by the NHTSA, and the eventual result was a 2010 law (Pedestrian Safety Enhancement Act of 2010) requiring electric and hybrid vehicle manufacturers to install devices which emit noise while traveling slower than about 19 mph. Higher speeds have tire and wind noise that’s sufficient for pedestrian needs. The implementation rules were finalized in February last year, and manufacturers have until September 1, 2020, to be fully compliant, with half of the vehicles equipped by September 1, 2019.
While the proposal may not be popular with all parties involved, the NHTSA points to its October 2009 report entitled “Research on Quieter Cars and the Safety of Blind Pedestrians, a Report to Congress” as a primary basis for its rulemaking. In the report, the agency found an increased rate of accidents involving pedestrians with hybrid-electric vehicles compared to ICE vehicles in roadways and zones with low-speed limits, during the type of weather or any time of day. By implementing the rules as passed, the NHTSA expects to prevent 2,400 injuries and reduce the $250-$320 million costs which result annually due to limited ability to detect quiet EVs/HEVs.

Another coming requirement is that the noise emitted must be identifiable as a vehicle, a limitation that will likely only inspire creativity. If manufacturers want to take a fun route with the noise options, i.e, license the Jetson family’s flying car sound from Hanna Barbara as suggested by Erik, they’ll have to make sure it’s consistent among their vehicles – or at least consistent among package options. Also, drivers cannot be allowed to modify the sound themselves.
Manufacturers are free to modify the sounds from the factory end, though, an option Tesla’s CEO Elon Musk has previously capitalized on for other noise-centric features in the electric car company’s vehicles. However, letting drivers determine their car’s noise via app or button push is still in the air. The NHTSA will publish a separate document at a later date to determine whether driver-selectable sounds are a good idea, or at least compliant with the purpose of the law.

What is Digital Optimus? The new Tesla and xAI project explained
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Tesla and xAI announced their groundbreaking joint project, Digital Optimus, also nicknamed “Macrohard” in a humorous jab at Microsoft, earlier this week.
This software-based AI agent is designed to automate complex office workflows by observing and replicating human interactions with computers. As the first major outcome of Tesla’s $2 billion investment in xAI, it represents a powerful fusion of hardware efficiency and advanced reasoning.
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Macrohard or Digital Optimus is a joint xAI-Tesla project, coming as part of Tesla’s investment agreement with xAI.

Tesla’s specialized AI acts as “System 1”—the fast, instinctive executor—processing the past five seconds of real-time computer screen video along with keyboard and mouse actions to perform immediate tasks.
xAI’s Grok model serves as “System 2,” the strategic “master conductor” or navigator, providing high-level reasoning, world understanding, and directional oversight, much like an advanced turn-by-turn navigation system.
When combined, the two can create a powerful AI-based assistant that can complete everything from accounting work to HR tasks.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
The system runs primarily on Tesla’s low-cost AI4 inference chip, minimizing expensive Nvidia resources from xAI for competitive, real-time performance.
Elon Musk described it as “the only real-time smart AI system” capable, in principle, of emulating the functions of entire companies, handling everything from accounting and HR to repetitive digital operations.
Timelines point to swift deployment. Announced just days ago, Musk expects Digital Optimus to be ready for user experience within about six months, targeting rollout around September 2026.
It will integrate into all AI4-equipped Tesla vehicles, enabling parked cars to handle office work during downtime. Millions of dedicated units are also planned for deployment at Supercharger stations, tapping into roughly 7 gigawatts of available power.
Oh and it works in all AI4-equipped cars, so your car can do office work for you when not driving.
We’re also deploying millions of dedicated Digital Optimus units in the field at Superchargers where we have ~7 gigawatts of available power.

Digital Optimus directly supports Tesla’s broader autonomy strategy. It leverages the same end-to-end neural networks, computer vision, and real-time decision-making tech that power Full Self-Driving (FSD) software and the physical Optimus humanoid robot.
By repurposing idle vehicle compute and extending AI4 hardware beyond driving, the project scales Tesla’s autonomy ecosystem from roads to digital workspaces.
As a virtual counterpart to physical Optimus, it divides labor: software agents manage screen-based tasks while humanoid robots tackle physical ones, accelerating Tesla’s vision of general-purpose AI for productivity, Robotaxi fleets, and beyond.
In essence, Digital Optimus bridges Tesla’s vehicle and robotics autonomy with enterprise-scale AI, promising massive efficiency gains. No other company currently matches its real-time capabilities on such accessible hardware.
It really could be one of the most crucial developments Tesla and xAI begin to integrate, as it could revolutionize how people work and travel.

Interestingly, we’re not too sure what catalyzed Tesla to try to improve braking smoothness, because it hasn’t seemed overly abrupt or rough from my perspective. Although the brake pedal in my Model Y is rarely used due to Regenerative Braking, it seems Tesla wanted to try to make the ride comfort even smoother for owners.
There is always room for improvement, though, and it seems that there is a way to make braking smoother for passengers while the vehicle is coming to a stop.
This is far from the first time Tesla has attempted to improve its ride comfort through Over-the-Air updates, as it has rolled out updates to improve regenerative braking performance, handling while using Full Self-Driving, improvements to Steer-by-Wire to Cybertruck, and even recent releases that have combatted Active Road Noise.
Tesla holds a unique ability to change the functionality of its vehicles through software updates, which have come in handy for many things, including remedying certain recalls and shipping new features to the Full Self-Driving suite.
Tesla seems to have the most seamless OTA processes, as many automakers have the ability to ship improvements through a simple software update.
We’re really excited to test the update, so when we get an opportunity to try out Comfort Braking when it makes it to our Model Y.

Tesla finally brings a Robotaxi update that Android users will love
The breakdown of the software version shows that Tesla is actively developing an Android-compatible version of the Robotaxi app, and the company is developing Live Activities for Android.
Tesla is finally bringing an update of its Robotaxi platform that Android users will love — mostly because it seems like they will finally be able to use the ride-hailing platform that the company has had active since last June.
Based on a decompile of software version 26.2.0 of the Robotaxi app, Tesla looks to be ready to roll out access to Android users.
According to the breakdown, performed by Tesla App Updates, the company is preparing to roll out an Android version of the app as it is developing several features for that operating system.
🚨 It looks like Tesla is preparing to launch the Robotaxi app for Android users at last!

The breakdown of the software version shows that Tesla is actively developing an Android-compatible version of the Robotaxi app, and the company is developing Live Activities for Android:
“Strings like notification_channel_robotaxid_trip_name and android_native_alicorn_eta_text show exactly how Tesla plans to replicate the iOS Live Activities experience. Instead of standard push alerts, Android users are getting a persistent, dynamically updating notification channel.”
This is a big step forward for several reasons. From a face-value perspective, Tesla is finally ready to offer Robotaxi to Android users.
The company has routinely prioritized Apple releases because there is a higher concentration of iPhone users in its ownership base. Additionally, the development process for Apple is simply less laborious.
Tesla is working to increase Android capabilities in its vehicles
Secondly, the Robotaxi rollout has been a typical example of “slowly then all at once.”
Tesla initially released Robotaxi access to a handful of media members and influencers. Eventually, it was expanded to more users, so that anyone using an iOS device could download the app and hail a semi-autonomous ride in Austin or the Bay Area.
Opening up the user base to Android users may show that Tesla is preparing to allow even more users to utilize its Robotaxi platform, and although it seems to be a few months away from only offering fully autonomous rides to anyone with app access, the expansion of the user base to an entirely different user base definitely seems like its a step in the right direction.
