Tesla is implementing a new hazard light pattern that improves drivers' attention

Emergency Safety Solutions

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 Vehicles Spotted With LiDAR: What Do They Use It For?

July 13, 2024

Tesla recently hit the news for purchasing approximately $2M in LiDAR sensors from Luminar, one of Tesla’s long-term suppliers. You’ve probably seen photos of Tesla’s Semi and various Tesla models, including the Model 3 and Model Y sporting LIDAR equipment on the roof. These cars drive around with manufacturer plates scanning streets and highways.

However, many people confuse Tesla’s purpose in purchasing LiDAR equipment with using it for FSD versus testing. So, let’s look at what LiDAR is, and why Tesla uses it on its Fleet Validation Vehicles.

What is LiDAR?

LiDAR stands for Light Detecting and Ranging – essentially using lasers to measure distances. A laser pulse is sent out, and the time it takes to return is measured – providing extremely accurate distance measurements.

Some companies working on self-driving vehicles, including Waymo and BYD, use LiDAR as part of their self-driving suites, but Tesla is one of the few stand-outs that does not. Even Rimac’s “Verne” Robotaxi – which uses self-driving technology from Mobileye, also uses LiDAR.

While LiDAR can produce extremely accurate and high-quality 3D environments, it comes with its downsides as well. Not only is LiDAR costly and requires large gear strapped to a vehicle, but it also can not be used in bad weather and can have interference issues if there are other strong light sources present.

Why Does Tesla Use LiDAR?

At Autonomy Day in 2019, Elon Musk mentioned that LiDAR isn’t the solution for self-driving cars – it's just a crutch. Thus, Tesla hasn’t used LiDAR for any production self-driving software.

Instead, Tesla uses it exactly how it's described – they use it to gather ground-truth data. This data is then used to feed Tesla’s Full Self Driving system – which helps validate its vision-only system's accuracy. LiDAR provides very accurate measurements to help ensure that FSD’s perception of space is accurate – and is only used by Tesla to ensure that its AI technology which is the brains of FSD is capable of accurately interpreting depth from just visual data.

Tesla’s vision-only system has been seen to be extremely accurate, with Vision-only Autopark being able to park in even narrower and tighter spaces faster than the previous version that relied on ultrasonic sensors.

We’ll likely continue to see Tesla purchase LiDAR systems, as well as use them for validation well into the future.

Tesla's Upcoming Robotaxi Event in August Delayed, According to Bloomberg

July 12, 2024

In a report from Bloomberg, it is claimed that Tesla will be delaying its much-anticipated 8/8 Robotaxi event by two months to October 2024.

While sources other than Bloomberg haven't confirmed this report, Bloomberg has a positive track record of reporting on financial decisions. We’ll be sure to update the article if there is confirmation on X from Elon Musk or another Tesla senior official.

Tesla’s stock has dropped nearly 8.5% over the day, ending back-to-back gains over the last two weeks. It closed yesterday at $ 241 after hitting a peak of $270 earlier in the day before the news broke.

Why the Delay?

The delay – of approximately two months – has been communicated internally, but not publicly announced just yet. Bloomberg goes on to mention that the design team was told to rework certain elements of the Cybercab, necessitating the delay.

If Bloomberg’s report is correct, it sounds like Tesla’s unveil event will be largely focused on showing off the vehicle, instead of demoing how it will work. Of course, it could still be both, but given past events, Tesla has always shown off the vehicle years before it hits production.

Rimac recently showed off their version of robotaxi vehicle named Verne, and surprisingly, it could almost pass for Tesla’s own robotaxi. A lot of design cues in Rimac’s version are elements we have already seen or expect to see in Tesla’s autonomous taxi.

A recent Tesla patent revealed that Tesla is incorporating a sanitation system into their robotaxi that will be responsible for analyzing and cleaning the vehicle’s interior, although the delay itself is likely tied more to a physical feature rather than software.

Another element we know almost nothing about is how Tesla plans to charge these robotic taxis. Will they rely on the existing charge port and adapt a solution like the robotic charging arm (video below) we saw almost eight years ago, or will wireless charging or a dock finally become realized?

While the delay for Tesla’s event appears to be related to the vehicle’s design itself and not further development of FSD, Tesla is wasting no time in getting FSD working for the upcoming vehicle. Model 3 vehicles have already been spotted with camera locations that resemble a robotaxi.

Is the Delay Accurate?

We expect that this delay might actually be true – Elon Musk usually takes to X within hours of such news breaking if it's false to refute it and hasn’t done so yet.

Tesla has delayed several of their events in the past, and a delay of a couple of months seems plausible. We should hear from Musk himself soon on whether this report is accurate.
