Tesla is rolling out a significant safety enhancement through a software update. Teslas, already the safest vehicles on the planet, got a little safer thanks to a small company based in Texas. While this article will highlight the advancement in safety, it will also applaud the work of Emergency Safety Solutions, which dared to challenge the old way of doing things.

Overnight Evolution: The Game Changer

Tesla North America didn't mince words when they announced: "If an airbag is deployed, hazard lights will automatically activate & flash faster to improve visibility." Elon Musk added, "New Tesla safety feature uploaded via over-the-air software update. Your car just got better while you slept."

It got much better thanks to a partnership with Emergency Safety Solutions (ESS), which we spotlighted a year ago. The small company, now just five years old, used a Tesla Model 3 to display its advancements in the hazard lights system, which had remained unchanged for more than 70 years. After numerous studies, the company changed everything about the hazard lights and approached Tesla with its findings.

Chilling Frequency: Every seven minutes, a disabled vehicle is involved in a crash on American roads. The result? An alarming 15,000 injuries or fatalities annually.

Ancient Flaws: The primary culprit behind these startling figures is a hazard light system that hasn't been updated in over seven decades.

The Solution: A frequency shift by adjusting flash frequencies from the sluggish 1.5Hz system to between 4Hz and 6Hz immensely heightens driver alertness. Hertz is a unit of frequency, which equals the number of cycles per second. In this case, the frequency of flashing lights is increased from 1.5 flashes per second, up to 4 - 6 flashes per second.

Real-World Outcomes: When 5Hz flash frequency was tested, drivers reacted a crucial 12 seconds faster. Moreover, they recognized an issue of more than three football fields sooner than the 70-year version. The number of drivers shifting to the safer side of a disabled vehicle also shot up dramatically — from 30% to an impressive 87%.

Emergency Safety Solutions also posted on X: "Great step toward making our roads safer for people in disabled and vulnerable vehicles! We appreciate our partnership with Tesla and applaud this major milestone in our mission to protect drivers when they need it most."

Software Update

Tesla states in their post on X that this update is rolling out now in the U.S. to Model 3/Y vehicles and newer Model S and Xs.

It's not clear whether Tesla means this enhancement is available in update 2023.32, or whether it's in the upcoming 2023.38 update, which is currently in employee testing.

It's more likely that H.E.L.P. is implemented in update 2023.38, but we have yet to receive release notes for vehicles in the U.S., so we'll have to wait and see if this enhancement made it in.

More H.E.L.P. to Come

Keep an eye out for even more safety advancements courtesy of this partnership with ESS and Tesla. The company created the Hazard Enhanced Location Protocol or HELP. Beyond the lightning-fast flashes, HELP seamlessly integrates with in-car and phone navigation systems, giving drivers a heads-up about potential hazards before they become visible. It's like giving your Tesla a sixth sense.

Unfortunately, that will take longer as it would require more automakers to get on board with this new system. However, as we've realized, automakers are following Tesla's leadership on several fronts, and they may also increase road safety and implement the advanced system.

Tesla Updates Energy App in Update 2025.8.3: Adds Reset and Distance Filter [VIDEO]

Tesla recently launched software update 2025.8.3, which included a bunch of “minor updates.” Nestled away in the release notes are a couple of interesting features - including some major changes to the Energy App.

We’re not quite sure we’d call these minor updates, so let’s take a bit of an exploration of the revitalized Energy App.

Update 2025.8.3

Select Distance in Energy App

The Energy App has received some new categorization features in the Consumption tab. You can once again limit the graph by distance. As part of the 2024 Holiday Update, Tesla redesigned the consumption tab and brought it to the new Model S and Model X for the first time. However, with the redesign, Tesla removed the ability to choose the distance shown in the graph, instead providing a static display of the last 200 miles (300km). 

The first part of the improved Energy App is bringing back this distance filter. You can now choose between showing the last 10, 100, or 200 miles (15, 150, or 300 km). This differs from the previous available distances of 5, 15 and 30 miles, but brings back the ability for the driver to choose a distance that may be more applicable to how they’re driving.

We’d love for Tesla to introduce custom distances by pinching and zooming the graph or simply add the ability to choose “This Drive Only” to the list of available distances.

Reset Energy App History

@EV3_Model3 on X

Sadly, the “Instant Range” button that was available in the Energy App before is still not available, but Tesla introduced a new feature that may be even better. You can now clear your driving history so that the graph only reflects your current driving style.

This is a little hidden, but if you tap the little info icon at the top near your average Wh/mi, you’ll now be presented with a dialog that lets you clear your history.

This could be useful if you’ve just come from some hard driving on a track or off-road, where energy consumption could be exaggerated. It could also be useful if you just started towing or a different type of driving that is drastically different from your current driving.

Other Changes

In addition, it looks like future predictions of the Energy app now take into account your driving history and apply that in addition to expected vehicle consumption, weather, altitude, and the multitude of other factors that your Tesla constantly takes into account while calculating your expected range.

While these are smaller improvements to the Energy app, they added some important functionality, as it helps users better understand their vehicle consumption and display data that is more applicable to the current driving style.

This is a great example of Tesla listening to its customers and bringing back features they had previously been removed. Check out the video below by akide on the updated Energy app in update 2025.8.3.

Franz and Lars Discuss the Tesla Cybercab in New Interview

By Not a Tesla App Staff
Munro Live

Sandy Munro once again had the opportunity to chat (video below) with Lars Moravy, Tesla’s Vice President of Vehicle Engineering, as well as Franz Von Holzhausen, Tesla’s Chief of Vehicle Design. This time, rather than focusing on the improvements to the refreshed Model Y and all the new engineering behind it, the focus was on Tesla’s autonomous ambitions.

In this case, the Cybercab and Robovan were the key highlights, with a distinct focus on the Cybercab. With that all said, let’s dig into all the fun new stuff. You can check out the entire video at the end of the article.

Cybercab Unboxed Process

The Cybercab will be the first of Tesla’s vehicles to use their new unboxed assembly process, which builds vehicles in parallel sections, and then brings them together all at once for final assembly. Traditionally, vehicles are assembled from the ground up, and sometimes even disassembled for parts of production to take place.

This innovative method involves using a big rear and front casting, brought together by a structural battery pack on the floor. The door rings are hot-stamped and laser-welded to form the side shell of the Cybercab, resulting in a very rigid structure that can also absorb crash impacts due to its unique manufacturing.

Paint-Free Panels

We’ve already talked about the Cybercab’s unique paint-free panels, but we’ve never heard until now exactly how Tesla intends to manufacture them. Tesla will inject colored PU plastic onto the backside of another plastic part (formed from various processes) and then ultrasonically weld that entire piece to an inner part.

That essentially combines multiple parts into one smooth piece that is easy to repair - because all you have to do is remove the entire panel - it just comes off as the interior fasteners are removed. There is no subframe holding it together - instead, the subframe is part of the panel.

The only area of the vehicle that will have any paint will be the hot-stamped door rings - which will be painted to improve corrosion resistance to protect the steel.

Aerodynamics

Aerodynamically, the Cybercab boasts the largest aero-cover-to-wheel ratio of any Tesla vehicle. This updated aero cover improves efficiency, even with the Cybercab’s relatively large tires—chosen to reduce rolling resistance. Interestingly, the impact of unsprung weight on efficiency is minimal compared to the benefits of improved rolling resistance and aerodynamics.

Another key to the aerodynamics is the teardrop shape of the Cybercab itself. With its low profile and smooth shape, it is extremely aerodynamically efficient. While neither Sandy nor Lars delved into drag coefficients, we expect it will likely be more efficient than the Model 3’s already fantastic Cd of 0.219.

Range and Battery Pack

Tesla currently has prototypes undergoing real-world testing at Giga Texas to evaluate range and efficiency. The goal is to ensure the vehicle can operate throughout an entire day in the city before returning to charge.

Tesla is targeting a battery pack under 50kWh, delivering close to 300 miles of real-world range—an impressive efficiency of around 166Wh/mi, even outperforming the Model 3’s lowest at 181Wh/mi.

When Does It Arrive?

So, with all that new knowledge - when does the Cybercab arrive? Well - the prototypes for the June Robotaxi network deployment in Austin are getting prepared now - but Tesla expects to begin production and sales sometime in the first half of 2026.
