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.

Tesla Semi’s official battery capacity leaked by California regulators
A California regulatory filing just confirmed the exact battery size inside each Tesla Semi variant.
A regulatory filing published by the California Air Resources Board in April 2026 has put official numbers on what Tesla Semi owners and fleet buyers have long wanted confirmed: the exact battery capacities of both the Long Range and Standard Range Semi truck variants. CARB is California’s independent air quality regulator, and it certifies zero-emission powertrains before they can be sold or operated in the state. When a manufacturer submits a vehicle for certification, the resulting executive order becomes a public document, making it one of the most reliable sources for confirmed production specs on any EV.
The document lists two certified powertrain configurations. The Long Range Semi carries a usable battery capacity of 822 kWh, while the Standard Range version comes in at 548 kWh. Both use lithium-ion NCMA chemistry and share the same peak and steady-state motor output ratings of 800 kW and 525 kW respectively. Cross-referencing Tesla’s published efficiency figure of approximately 1.7 kWh per mile under full load, the 822 kWh pack supports roughly 480 miles of real-world range, which aligns closely with Tesla’s advertised 500-mile figure for the Long Range trim. The 548 kWh Standard Range pack works out to approximately 320 miles, again consistent with Tesla’s stated 325-mile target.
Here is a direct comparison of the two versions based on the CARB filing and published specs:
| Tesla Semi Spec | Long Range | Standard Range |
| Battery Capacity | 822 kWh | 548 kWh |
| Battery Chemistry | NCMA Li-Ion | NCMA Li-Ion |
| Peak Motor Power | 800 kW | 525 kW |
| Estimated Range | ~500 miles | ~325 miles |
| Efficiency | ~1.7 kWh/mile | ~1.7 kWh/mile |
| Est. Price | ~$290,000 | ~$260,000 |
| GVW Rating | 82,000 lbs | 82,000 lbs |
The timing of this certification is not incidental. On April 29, 2026, Semi Programme Director Dan Priestley confirmed on X that high-volume production is now ramping at Tesla’s dedicated 1.7-million-square-foot facility in Sparks, Nevada. A key advantage of the Nevada location is vertical integration: the 4680 battery cells powering the Semi are manufactured in the same complex, eliminating the supply chain bottleneck that had delayed the program for years.
Tesla’s long-term goal is to reach a production capacity of 50,000 trucks annually at the Nevada factory, which would represent roughly 20 percent of the entire North American Class 8 market. With CARB certification now in hand and the production line running, the regulatory and manufacturing groundwork for that target is in place.
Tesla became the first company to pass the United States government’s new Advanced Driver Assistance Systems (ADAS) testing with the Model Y, completing each of the new tests with a passing performance.
In a landmark announcement on May 7, the National Highway Traffic Safety Administration (NHTSA) declared the 2026 Tesla Model Y the first vehicle to pass its newly ADAS benchmark under the New Car Assessment Program (NCAP).
Model Y vehicles manufactured on or after November 12, 2025, met rigorous pass/fail criteria for four newly added tests—pedestrian automatic emergency braking, lane keeping assistance, blind spot warning, and blind spot intervention—while also satisfying the program’s original four ADAS requirements: forward collision warning, crash imminent braking, dynamic brake support, and lane departure warning.
The NHTSA has just officially announced that the 2026 @Tesla Model Y is the first vehicle model to pass the agency’s new advanced driver assistance system tests.

NHTSA administration Jonathan Morrison hailed the achievement as a milestone:
“Today’s announcement marks a significant step forward in our efforts to provide consumers with the most comprehensive safety ratings ever. By successfully passing these new tests, the 2026 Tesla Model Y demonstrates the lifesaving potential of driver assistance technologies and sets a high bar for the industry. We hope to see many more manufacturers develop vehicles that can meet these requirements.”
The updates to NCAP, finalized in late 2024 and effective for 2026 models, reflect growing recognition that ADAS features are no longer optional luxuries but essential tools for preventing crashes.
Pedestrian automatic emergency braking, for instance, targets one of the fastest-rising causes of roadway fatalities, while blind spot intervention and lane keeping assistance address common sources of side-swipes and run-off-road incidents. By incorporating objective, performance-based evaluations rather than mere presence of the technology, NHTSA aims to give buyers clearer data on real-world effectiveness.
This milestone arrives at a pivotal moment when vehicle autonomy is transitioning from science fiction to everyday reality.
Tesla’s Full Self-Driving (FSD) software and the impending rollout of robotaxis underscore a broader industry shift toward higher levels of automation. Yet regulators and consumers remain cautious: safety data must keep pace with technological ambition.
The Model Y’s perfect score on these ADAS benchmarks validates that current driver-assist systems—when engineered rigorously—can dramatically reduce human error, which still accounts for the vast majority of crashes.
For Tesla, the result reinforces its long-standing claim of building the safest vehicles on the road. More importantly, it signals to the entire auto sector that meeting elevated federal standards is achievable and expected.
As autonomy edges closer to Level 3 and beyond, where drivers may disengage more fully, such independent verification becomes critical. It builds public trust, informs purchasing decisions, and accelerates the development of systems that could one day eliminate tens of thousands of annual traffic deaths.
In an era when software-defined vehicles promise transformative mobility, the 2026 Model Y’s NHTSA triumph is more than a manufacturer accolade—it is a regulatory green light that autonomy’s future must be built on proven, testable safety foundations. The bar has been raised. The industry, and the roads we share, will be safer for it.
Tesla is going to fix the nearly 219,000 vehicles that it recalled due to an issue with the rearview camera with a simple software update, giving owners no need to travel to a service center to resolve the problem.
Tesla is formally recalling 218,868 U.S. vehicles after regulators discovered a software glitch that can delay the rearview camera image by up to 11 seconds when drivers shift into reverse.
The affected models include certain 2024-2025 Model 3 and Model Y, as well as 2023-2025 Model S and Model X vehicles running software version 2026.8.6 and equipped with Hardware 3 computers. The National Highway Traffic Safety Administration (NHTSA) determined the lag violates Federal Motor Vehicle Safety Standard 111 on rear visibility and could increase crash risk.
Yet this is no ordinary recall. Owners do not need to schedule a service-center visit, hand over keys, or wait for parts.
Tesla fans call for recall terminology update, but the NHTSA isn’t convinced it’s needed
Tesla identified the issue on April 10, halted further deployment of the faulty firmware the same day, and began pushing a corrective over-the-air (OTA) software update on April 11.
By the time the NHTSA posted the recall notice on May 6, more than 99.92 percent of the affected fleet had already received the fix. Tesla reports no crashes, injuries, or fatalities linked to the glitch.
The episode underscores a deeper problem with regulatory language. For decades, “recall” meant hauling a vehicle to a dealership for hardware repairs or replacements. That definition no longer fits software-defined cars. When a fix arrives wirelessly in minutes — identical to an iPhone update — the term evokes unnecessary alarm and misleads the public about the actual risk and remedy.
Elon Musk has repeatedly called for exactly this change. After earlier NHTSA actions, he stated plainly: “The terminology is outdated & inaccurate. This is a tiny over-the-air software update.” On another occasion, he added that labeling OTA fixes as recalls is “anachronistic and just flat wrong.”
The terminology is outdated & inaccurate. This is a tiny over-the-air software update. To the best of our knowledge, there have been no injuries.
— Elon Musk (@elonmusk) September 22, 2022
Musk’s point is simple: regulators must evolve their vocabulary to match the technology. Traditional recalls involve physical intervention and downtime; OTA updates do not. Retaining the old label distorts consumer perception, inflates perceived defect rates, and slows the industry’s shift to faster, safer software iteration.
Tesla’s rapid, remote remedy demonstrates the safety advantage of over-the-air capability. Problems that once required weeks of dealer appointments are now resolved in hours, often before most owners notice. As more automakers adopt software-first designs, the entire regulatory framework needs to catch up.
Updating “recall” terminology would align language with reality, reduce public confusion, and recognize that modern vehicles are no longer static hardware — they are continuously improving computers on wheels.
For the 219,000 Tesla owners involved, the process is already complete. The camera works, the car is safe, and no one left their driveway. That is the new standard — and the vocabulary should reflect it.
