In the aftermath of a tragic crane collapse in Fort Lauderdale, Florida, which tragically claimed the life of a construction worker and inflicted injuries upon others, the resilience and advanced safety features of a Tesla involved in the incident have been brought into focus.
As we offer our deepest sympathies to all affected by this unbelievable event, it's also important to recognize the role of advanced technology, particularly the engineering of Tesla vehicles, in safeguarding human life under such extreme circumstances. This unfortunate incident serves as a poignant reminder of Tesla's unwavering commitment to safety, illustrating the capability of its vehicles to offer protection in the most unpredictable situations.
A Testament to Tesla's Safety
Mark Cerezin, behind the wheel of his Tesla, experienced an unimaginable scare. He described it to NBC Miami, “I felt a compression. I looked up, and I saw the blue structure coming down. I slammed on my brakes. It sheered off the front of my Tesla, and all the airbags went off. I’m very lucky to be alive.” Despite the severity of the incident, Cerezin not only emerged completely unharmed, he was then seen helping someone else who appeared to have a head injury. “There was a lady that was bleeding, and I took off my shirt and put compression and helped her,” he said.
“From this day forward, I’m just happy to go home to my wife. I’m happy to go home to my family and my friends. I’m just so grateful,” he said. This remarkable escape underscores the exceptional structural integrity and safety design of Tesla vehicles, engineered to protect occupants even under the most dire circumstances.
Tesla's Safety Philosophy
Tesla's approach to vehicle safety is holistic, integrating active and passive safety features. The brand's vehicles are renowned for their high ratings in crash tests conducted by safety organizations worldwide. This results from meticulous engineering, from the vehicle's frame design to cutting-edge driver-assistance technologies.
Vice President of Vehicle Engineering Lars Moravy showed viewers the cornerstone principles behind Tesla's acclaimed safety features. Central to Tesla's design philosophy is a robust passive safety system aimed at protecting occupants and the vehicle's battery in the event of an accident. This includes a progressive crash structure designed to absorb impact energy before it reaches the cabin, multiple load paths for effective energy distribution regardless of collision type, and reinforced cabin safety through strategic placement of door rings, glass, and a low-situated battery that also lowers the center of gravity to reduce rollover risks.
Conclusion
As Tesla continues to innovate and refine its vehicles, the emphasis on safety remains paramount. The brand's commitment to meeting and exceeding safety standards is reflected in the sophisticated safety technologies embedded in each model, from Autopilot to advanced airbag systems. Tesla's ongoing dedication to safety innovation advances its mission toward sustainable transportation and ensures that drivers and passengers are afforded the highest levels of protection possible.

Tesla’s been on a roll with Supercharger improvements lately, from the 325kW charging update for the Cybertruck, to 500kW with V4 Superchargers coming next year. While those improvements have been limited to the Cybertruck, Tesla didn’t put all their focus on their new flagship vehicle, but looked at their more affordable vehicles as well.
LFP Battery Heating
Tesla’s Superchargers can now heat LFP Batteries - those that are in the Model 3 and Model Y Rear Wheel Drive variants. This applies to Long Range and Standard Range models, which saw a limited run. This is another update included as part of the 2024 Tesla Holiday Update - which really arrived with a lot of unannounced new features and capabilities.
The change is pretty interesting - Superchargers of the V3 and V4 variety can now pre-heat batteries for Model 3 and Model Y vehicles equipped with LFP battery packs. That means those vehicles are able to get back on the road faster when it's extremely cold. Of course, Tesla still advises you to precondition before you arrive, saving drivers time and money.
Max de Zegher, Tesla’s Director of Charging, also commented on the new feature. Essentially, Tesla is inducing an AC (alternating) ripple current through the battery to warm it up. Keep in mind that Superchargers are DC charging. That means it is possible to get a cold-soaked LFP vehicle on the road 4x faster than before, assuming that it didn’t precondition at all and that it is in the worst-case scenario (below 0ºF).
In essence, Tesla is using some engineering magic to turn the circuits inside the LFP battery into an electric heater - and powering that heater through the Supercharger. An AC ripple current is a small oscillation in the DC charging current that generates heat through electrical resistance, warming up the battery. Those ripples are a byproduct of converting AC to DC and back - so Tesla is using the onboard charger to induce those ripples to warm up the battery. Definitely an innovative technique that’s really only possible with the versatility of the NACS connector.
We’re hoping Tesla can implement this across their full lineup of vehicles, but we’ll have to wait and see how it is trialed across LFP vehicles first and if it is even possible on vehicles with 2170 or 4680 battery packs.
Tesla launched two FSD updates simultaneously on Saturday night, and what’s most interesting is that they arrived on the same software version. We’ll dig into that a little later, but for now, there’s good news for everyone. For Hardware 3 owners, FSD V12.6.1 is launching to all vehicles, including the Model 3 and Model Y. For AI4 owners, FSD V13.2.4 is launching, starting with the Cybertruck.
FSD V13.2.4
A new V13 build is now rolling out to the Cybertruck and is expected to arrive for the rest of the AI4 fleet soon. However, this build seems to be focused on bug fixes. There are no changes to the release notes for the Cybertruck with this release, and it’s unlikely to feature any changes when it arrives on other vehicles.
FSD V12.6.1 builds upon V12.6, which is the latest FSD version for HW3 vehicles. While FSD V12.6 was only released for the redesigned Model S and Model X with HW3, FSD V12.6.1 is adding support for the Model 3 and Model Y.
While this is only a bug-fix release for users coming from FSD V12.6, it includes massive improvements for anyone coming from an older FSD version. Two of the biggest changes are the new end-to-end highway stack that now utilizes FSD V12 for highway driving and a redesigned controller that allows FSD to drive “V13” smooth.
It also adds speed profiles, earlier lane changes, and more. You can read our in-depth look at all the changes in FSD V12.6.
Same Update, Multiple FSD Builds
What’s interesting about this software version is that it “includes" two FSD updates, V12.6.1 for HW3 and V13.2.4 for HW4 vehicles. While this is interesting, it’s less special when you understand what’s happening under the hood.
The vehicle’s firmware and Autopilot firmware are actually completely separate. While a vehicle downloading a firmware update may look like a singular process, it’s actually performing several functions during this period. First, it downloads the vehicle’s firmware. Upon unpacking the update, it’s instructed which Autopilot/FSD firmware should be downloaded.
While the FSD firmware is separate, the vehicle can’t download any FSD update. The FSD version is hard-coded in the vehicle’s firmware that was just downloaded. This helps Tesla keep the infotainment and Autopilot firmware tightly coupled, leading to fewer issues.
What we’re seeing here is that HW3 vehicles are being told to download one FSD version, while HW4 vehicles are being told to download a different version.
While this is the first time Tesla has had two FSD versions tied to the same vehicle software version, the process hasn’t actually changed, and what we’re seeing won’t lead to faster FSD updates or the ability to download FSD separately. What we’re seeing is the direct result of the divergence of HW3 and HW4.
While HW3/4 remained basically on the same FSD version until recently, it is now necessary to deploy different versions for the two platforms. We expect this to be the norm going forward, where HW3 will be on a much different version of FSD than HW4. While each update may not include two different FSD versions going forward, we may see it occasionally, depending on which features Autopilot is dependent on.
