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.

Tesla arsonist who burned Cybertruck sees end of FAFO journey
The man has now reached the “Find Out” stage.
A Mesa, Arizona man has been sentenced to five years in federal prison for setting fire to a Tesla location and vehicle in a politically motivated arson attack, federal prosecutors have stated.
The April 2025 incident destroyed a Tesla Cybertruck, endangered first responders, and triggered mandatory sentencing under federal arson laws.
A five-year sentence
U.S. District Judge Diane J. Humetewa sentenced Ian William Moses, 35, of Mesa, Arizona, to 5 years in prison followed by 3 years of supervised release for maliciously damaging property and vehicles by means of fire. Moses pleaded guilty in October to all five counts brought by a federal grand jury. Restitution will be determined at a hearing scheduled for April 13, 2026.
As per court records, surveillance footage showed Moses arriving at a Tesla store in Mesa shortly before 2 a.m. on April 28, 2025, carrying a gasoline can and backpack. Investigators stated that he placed fire starter logs near the building, poured gasoline on the structure and three vehicles, and ignited the fire. The blaze destroyed a Tesla Cybertruck. Moses fled the scene on a bicycle and was arrested by Mesa police about a quarter mile away, roughly an hour later.
Authorities said Moses was still wearing the same clothing seen on camera at the time of his arrest and was carrying a hand-drawn map marking the dealership’s location. Moses also painted the word “Theif” on the walls of the Tesla location, prompting jokes from social media users and Tesla community members.
The “Finding Out” stage
U.S. Attorney Timothy Courchaine noted that Moses’ sentence reflects the gravity of his crime. He also highlighted that arson is never acceptable.
“Arson can never be an acceptable part of American politics. Mr. Moses’ actions endangered the public and first responders and could have easily turned deadly. This five-year sentence reflects the gravity of these crimes and makes clear that politically fueled attacks on Arizona’s communities and businesses will be met with full accountability.”
Maricopa County Attorney Rachel Mitchell echoed the same sentiments, stating that regardless of Moses’ sentiments towards Elon Musk, his actions are not defensible.
“This sentence sends a clear message: violence and intimidation have no place in our community. Setting fire to a business in retaliation for political or personal grievances is not protest, it is a crime. Our community deserves to feel safe, and this sentence underscores that Maricopa County will not tolerate political violence in any form.”

Tesla says its Texas lithium refinery is now operational and unlike anything in North America
Elon Musk separately described the site as both the most advanced and the largest lithium refinery in the United States.
Tesla has confirmed that its Texas lithium refinery is now operational, marking a major milestone for the company’s U.S. battery supply chain. In a newly released video, Tesla staff detailed how the facility converts raw spodumene ore directly into battery-grade lithium hydroxide, making it the first refinery of its kind in North America.
Elon Musk separately described the site as both the most advanced and the largest lithium refinery in the United States.
A first-of-its-kind lithium refining process
In the video, Tesla staff at the Texas lithium refinery near Corpus Christi explained that the facility processes spodumene, a lithium-rich hard-rock ore, directly into battery-grade lithium hydroxide on site. The approach bypasses intermediate refining steps commonly used elsewhere in the industry.
According to the staff, spodumene is processed through kilns and cooling systems before undergoing alkaline leaching, purification, and crystallization. The resulting lithium hydroxide is suitable for use in batteries for energy storage and electric vehicles. Tesla employees noted that the process is simpler and less expensive than traditional refining methods.
Staff at the facility added that the process eliminates hazardous byproducts typically associated with lithium refining. “Our process is more sustainable than traditional methods and eliminates hazardous byproducts, and instead produces a co-product named anhydrite, used in concrete mixes,” an employee noted.
Musk calls the facility the largest lithium refinery in America
The refinery’s development timeline has been very impressive. The project moved from breaking ground in 2023 to integrated plant startup in 2025 by running feasibility studies, design, and construction in parallel. This compressed schedule enabled the fastest time-to-market for a refinery using this type of technology. This 2026, the facility has become operational.
Elon Musk echoed the significance of the project in posts on X, stating that “the largest Lithium refinery in America is now operational.” In a separate comment, Musk described the site as “the most advanced lithium refinery in the world” and emphasized that the facility is “very clean.”
By bringing large-scale lithium hydroxide production online in Texas, Tesla is positioning itself to reduce reliance on foreign refining capacity while supporting its growth in battery and vehicle production. The refinery also complements Tesla’s nascent domestic battery manufacturing efforts, which could very well be a difference maker in the market.

Tesla Optimus V3 gets early third-party feedback, and it’s eye-opening
Jason Calacanis’ remarks, which were shared during a discussion at CES 2026, offered one of the first third-party impressions of the yet-to-be-unveiled robot
Angel investor and entrepreneur Jason Calacanis shared some insights after he got an early look at Tesla’s upcoming Optimus V3. His remarks, which were shared during a discussion at CES 2026, offered one of the first third-party impressions of the yet-to-be-unveiled robot.
Calacanis’ comments were shared publicly on X, and they were quite noteworthy.
The angel investor stated that he visited Tesla’s Optimus lab on a Sunday morning and observed that the place was buzzing with energy. The investor then shared a rare, shocking insight. As per Calacanis, Optimus V3 will be so revolutionary that people will probably not even remember that Tesla used to make cars in the future.
“I don’t want to name drop, but two Sundays ago, I went to Tesla with Elon and I went and visited the Optimus lab. There were a large number of people working on a Sunday at 10 a.m. and I saw Optimus 3. I can tell you now, nobody will remember that Tesla ever made a car,” he noted.
The angel investor also reiterated the primary advantage of Optimus, and how it could effectively change the world.
“They will only remember the Optimus and that he is going to make a billion of those, and it is going to be the most transformative technology product ever made in the history of humanity, because what LLMs are gonna enable those products to do is understand the world and then do things in the world that we don’t want to do. I believe there will be a 1:1 ratio of humans to Optimus, and I think he’s already won,” he said.
While Calacanis’ comments were clearly opinion-driven, they stood out as among the first from a non-Tesla employee about Optimus V3. Considering his reaction to the humanoid robot, perhaps Elon Musk’s predictions for Optimus V3 might not be too far-fetched at all.
Tesla has been careful with its public messaging around Optimus V3’s development stage. Musk has previously stated on X that Optimus V3 has not yet been revealed publicly, clarifying that images and videos of the robot online still show Optimus V2 and V2.5, not the next-generation unit. As for Calacanis’ recent comments, however, Musk responded with a simple “Probably true” in a post on X.
