NHTSA says your Tesla can’t be this quiet starting Sept., 2019
We at Teslarati are all in favor of making vehicles as safe as possible. Indeed, in our research and analysis of Teslas, we were proud early on in 2013 when the National Highway Traffic Safety Administration (NHTSA) awarded the Tesla Model S a 5-star safety rating, not just overall, but in every subcategory without exception. It was so safe, in fact, that the all-electric sedan broke the testing equipment at an independent commercial facility. Fast-forward to 2015. The Model X was the first SUV to be five-star in every category, according to Tesla CEO Elon Musk. It even won the prestigious Golden Steering Wheel (Das Goldene Lenkrad) award for best SUV this year.
Safety is important and should be primary to any driving situation. It should prevail over luxury features, style, and even comfort. However, a new NHTSA regulation that purports to target safety in its language is little more than a superficial gesture within a larger framework of driver, passenger, and pedestrian concerns.
Federal Motor Vehicle Safety Standard No. 141, which will begin on September 1, 2019, requires all newly manufactured hybrid and electric light-duty vehicles to make an audible noise at speeds below 19 mph. The sound requirement has been designed to help pedestrians who are blind, have low vision, cyclists, and other pedestrians to detect the presence, direction, and location of hybrids and EVs traveling at low speeds. At higher speeds, the sound alert will not be required because other factors, such as tire and wind noise, seem to provide adequate audible warning to pedestrians and will not be the subject of this regulation.
“We all depend on our senses to alert us to possible danger,” said U.S. Transportation Secretary Anthony Foxx. “With more, quieter hybrid and electrical cars on the road, the ability for all pedestrians to hear as well as see the cars becomes an important factor of reducing the risk of possible crashes and improving safety.”
Creating a social environment in which all individuals — especially those with disabilities, underrepresented groups, children, and the elderly — are physically and psychologically welcomed and safe is absolutely paramount to a healthy community. Manufacturers and drivers of hybrids and EVs do have a responsibility to contribute to such an environment.
Yet, clearly, we have a generation who has been accustomed to the sounds and smells of internal combustion engines. Wouldn’t driver and pedestrian education be a more efficacious way to ensure that hybrids and EVs do not pose a safety threat? Daniel Kahneman’s (2013) work, Thinking Fast and Slow, suggests that innovative products require a higher degree of learning than existing products. Education to help EV drivers and individuals who do not have personal access to hybrids and EVS, thus, who have not built in conscious mechanisms toward the awareness of hybrids and EVs in traffic, would have longer lasting and more permanent results.
Making the case for educating pedestrians
As the general population increases its awareness of the risks of pollution to both health and the environment, the internal combustion engine has become less desirable. As a result, battery-powered, fuel-cell electric, and hybrid vehicles are technologically viable alternatives to the internal combustion engine. And they’re beginning to take on a significant segment of the U.S. vehicle market.
Essentially, an internal combustion engine works like a cannon. The sound that results is formidable and part of our collective U.S. psyche. It is ingrained in our psychological expectations of what an engine should be. Electric motors, however, make very little noise compared with an internal combustion engine. Research on the safety implications of quiet electric vehicles has mostly focused on pedestrians’ acoustic perception of EVs and suggests that EVs compromise traffic safety. However, Cocran & Krems‘ 2013 research determined that, based on gained individual experience, drivers adjust their evaluation of noise-related hazards. Some statistical observation studies in literature indicate that hybrid or EV drivers intend to be more careful, less risk takers in traffic (Horswill and Coster 2002). Thus, it makes sense to increase the awareness factors for everyone — EV drivers and pedestrians — to create more robust safe traffic situations when EVs are added to the vehicle mix.
Adding to the sound mix
Principles to increase awareness of hybrids and EVs have generally focused on alerts, or sounds that indicate the presence of an EV. Other principles, such as orientation mechanisms, which make it possible to determine where the vehicle is located, roughly how fast it is going, and whether it is moving toward or away from the listener, extend beyond mere white or overt noises.
Education transcends any of these physical additions to a hybrid or EV. Hybrid and EV drivers as well as pedestrians should be exposed to new conceptual thinking about the place of EVs in traffic situations. Alongside the new federal safety standard that requires low speed noise, hybrid and EV automakers can build in specific educational materials to prepare their consumer base for new driving situations, which will continue to add safety awareness. With access to multiple new technologies, drivers could have multimodal educational opportunities.
- Audio systems could provide periodic, random reminders to increase driver awareness of pedestrians and cyclists in slow speed situations.
- Automakers could require that drivers work through a series of interactive online tutorials that accentuate driver understanding of slow speed safety adaptations with hybrids and EVs.
- Traditional print manuals should include dedicated sections that address slow speed driver safety decision making.
- Before-driving checklists should include explicit instruction in slow speed situations and the possibility of pedestrian interactions.
Consumer safety groups can also assume responsibility for educating their constituents about new needs for pedestrian and cyclist awareness.
- Cyclist advocacy organizations can provide seminars to their members during events to increase strategies for hybrid and EV slow speed situations.
- Existing support groups for persons with visual impairment can add workshops about hybrid and EVs to empower them to anticipate potential slow speed traffic situations.
- Minimal training standards for service animals could include special animal recognition of hybrid and EVs.
- Traditional and highly respected elderly advocacy organizations like AARP could provide print and online materials to help a generation who grew up with internal combustion engines to accommodate strategies to recognize hybrids and EVs in traffic.
Yes, adoption and diffusion of new innovations can be a long-term, complicated process. Airbags, child safety features, exhaust gas hazard, seat belts, and driver assist technologies currently provide hybrid and EV drivers with a toolkit of pedestrian safety measures. But we want more than to prevent what NHTSA says is about 2,400 pedestrian injuries each year that occur during low speed hybrid or EV/ pedestrian interactions. We want to create a cultural climate in which a social vehicular knowledge base extends well beyond the internal combustion engine.

Elon Musk and Trump are closer than ever, and Tesla could be the big winner
Elon Musk sat beside Trump as AI leaders signed a voluntary White House safety accord.
Elon Musk had the seat right next to President Donald Trump on Tuesday as the White House hosted the leaders of America’s biggest artificial intelligence companies for a lunch that ended with a voluntary industry accord on AI safety.
A seating chart Trump posted on Truth Social placed Musk at the president’s left in the East Room, with Nvidia CEO Jensen Huang on his right, according to an Associated Press reporter. Anthropic CEO Dario Amodei, OpenAI President Greg Brockman, Meta’s Mark Zuckerberg, Google’s Sundar Pichai, Microsoft’s Satya Nadella and Amazon founder Jeff Bezos also attended, along with Vice President JD Vance and House Speaker Mike Johnson.

After the lunch, Trump told reporters outside the West Wing that the executives had signed “The White House Accord on Superintelligence: A Joint Commitment on Frontier SI Responsibilities.” Johnson described it as a voluntary statement of principles built on “robust internal controls and layers of internal and external review,” while Zuckerberg said company boards would independently review reports from outside auditors. Trump called the document “morally binding,” said he would name a new AI czar within days, and signed an executive order formally renaming artificial intelligence “super intelligence,” CNBC reported.
Musk was not in the room for Tesla alone. Since SpaceX absorbed xAI, he runs the company behind Grok and one of the largest AI training operations anywhere. On September 25, he said another 220,000 Nvidia GB300 chips would come online at Colossus 2 within a week, with more expected in November and December.
“I think it is worth highlighting the positive benefits of A.I. … S.I., pardon me.”

Musk also used the trip to restate his energy ambitions. “SpaceX is aiming together with Tesla to do 200 gigawatts of solar production per year,” he said at an event in Washington. It is the same combined target he laid out that feeds directly into Terafab, the Tesla and SpaceX chip venture that will need enormous amounts of power.
The showing between Musk and Trump has come a long way, since the two had the very public split in mid 2025 after Musk opposed the “Big Beautiful Bill” and left DOGE. They reconciled at Charlie Kirk’s memorial that September, and Trump later called their relationship “good”. Since then, Musk has joined Trump’s China delegation in May and attended last week’s White House state dinner for Chinese President Xi Jinping.
For Tesla, that access to government official could pay dividends. As Teslarati noted in January, federal autonomy rules, NHTSA oversight and a single national standard for driverless vehicles all run through an administration Musk can more easily reach directly as Tesla works to scale Robotaxi and Cybercab beyond Texas.
Ahead of its highly anticipated unveiling, Tesla’s upcoming Roadster received a new patent that aims to keep it grounded while enabling white-knuckle speeds.
The patent, which was granted on September 29, is titled “Electric Car Fan,” bluntly stating its design but not its purpose, which is further detailed in the text of the application. Interestingly, it comes two weeks before the Roadster event, which was delayed due to unfavorable weather on Thursday, which could cause issues, as Tesla revealed the event must be held outdoors.
🚨 The design uses electrically driven ducted fans, typically shown as a row of four at the rear, powered by the vehicle’s high-voltage battery.
The fans pull air from an underbody inlet, route it through ducts, and expel it from a larger rear outlet that functions as a… https://t.co/CHQB9u9UA3 pic.twitter.com/QVXmWTdggh

The purpose is to solve a problem that is relatively unique to high-performance electric cars. Instant motor torque is useless if the tires cannot plant that force, and conventional wings and underbody tunnels generate downforce only when air is already rushing past the car. At launch, in slow corners, and under hard braking from modest speed, passive aerodynamic additions contribute essentially very little to downforce.
Tesla’s filing says that its fans can produce the downforce needed, independent of vehicle velocity, then ease off so the same hardware does not pile on drag at highway speeds, an issue that can come from excessive body modifications.
The hardware outlined in the patent is a ducted-fan package that is placed into the rear of the vehicle. An underbody inlet between the rear wheels feeds a duct that rises to a wide outlet in the diffuser. In that outlet are four axial fans, which are divided by vertical strakes. They will pull air from under the floor and press the chassis onto the pavement.
The language in the patent claims it can cut drag rather than add to it while simultaneously increasing downforce.
Tesla Roadster event requires restricted airspace, and the FAA obliges
The fans run from the high-voltage battery and a vehicle control system, so output can be modulated rather than left on as a fixed penalty.
There are additional strengths that can come from this design, like extra tire load at low speed, which can contribute to even more face-melting acceleration rates, decrease stopping distance, and sharper turn-in before a wing has air to work with. Adjustable fan speed lets the car add grip only when needed, so it can be catered to the force of a turn or acceleration.
These designs were previously used, and banned, in some competitive settings. The Brabham BT46B was banned in F1 competition for using a similar fan design and being labeled as too effective.
Tesla still lists the Roadster as having a sub-two-second 0-60 MPH time and a 250-plus-MPH top speed, and there are expectations for a SpaceX cold-gas thruster package that could not only increase acceleration but potentially cause the vehicle to hover.
It is important to note that a patent is not a production part, and packaging four fans in a rear diffuser, managing noise, and potential debris are all things Tesla must consider. With that being said, the patent being granted shows Tesla is designing the Roadster to go fast, but it is also attempting to use unique strategies to combat any issues it might have at those speeds.
Tesla (NASDAQ: TSLA) showrooms have been picked clean ahead of the end of the third quarter of the year, as demand looks to be strong and delivery estimates for new vehicles are pushed into late 2026 and early 2027.
Tesla appears to have sold out of many of its Model 3 and Model Y trim levels in the United States, as only the Model Y RWD and Model Y All-Wheel-Drive are available for delivery before the end of the year.
Additionally, many showrooms are either completely empty or void of all but just one demo unit within the buildings themselves in an effort to bolster what could be one of Tesla’s best quarters in vehicle deliveries in recent memory.
I’m at Tesla right now and when I walked into their showroom I was shocked to see it basically empty.
I asked one of the people working there where all of the cars are “Gone – it’s the end of the quarter and we’ve sold out of everything… including the display vehicles”So… pic.twitter.com/rN7s3gE6sJ

Additionally, when I spoke to the guys at Tesla Mechanicsburg two weeks ago, when I returned the Model Y L, their third hauler of the week had just arrived, and every vehicle on it, along with every vehicle in their delivery lot, was accounted for and had a name attached to it for delivery.
Talking to the guys at the Mechanicsburg showroom on Friday, they couldn’t believe they had ANOTHER hauler coming in of cars for delivery—and each was accounted for
No car just sitting in inventory. They’re expecting a BIG quarter, and this is more than just the Y L https://t.co/ce801GkKVv

Tesla saw a 25 percent increase in deliveries in Q2 compared to the same quarter the year before. The vast majority of the 480,126 units it delivered, 467,762 vehicles to be exact, were the Model 3 and Model Y.
In Q3 2025, Tesla delivered 497,099 vehicles, once again a figure that was dominated by the company’s two mass-market vehicles. Analysts have unusually wide predictions for this quarter, likely because so many firms missed the Q2 delivery figure by such a substantial margin; Wall Street predicted 408,000 cars, while Tesla delivered 480,000.
Goldman Sachs has Tesla slotted for 435,000 deliveries in Q3, while JPMorgan said it anticipates 482,000. The median guess is about 449,000 deliveries for Q3.
