Tesla's Safety Score 2.1 update adjusts its evaluation criteria, particularly focusing on the Late-Night Driving metric. At the same time, the broader community continues to express concerns over other aspects of the system, notably the Forward Collision Warning.
Tesla has specifically addressed the Late-Night Driving metric, shifting the impactful driving window from 10 PM - 4 AM to 11 PM - 4 AM. This change directly responds to feedback regarding how late-night driving affects Safety Scores and, consequently, insurance premiums.
Addressing Concerns Beyond the Update
DriveTeslaCanada posted the story, which became quite a topic on Reddit. While the Late-Night Driving metric adjustment has been well-received, the Tesla community remains vocal about other system aspects, particularly the Forward Collision Warning’s sensitivity. Reports of frequent false alerts highlight a potential area for further improvement. Users suggest implementing a feature for manual incident reporting, using dashcam footage as evidence, to help refine the system's accuracy. Additionally, there's a call for Tesla to leverage such data to train its neural networks, aiming to reduce false positives.
Insurance and Safety Scores: Discussions extend to the implications of the Safety Score on Tesla Insurance premiums, with drivers sharing how updates and system sensitivities affect their scores and, subsequently, their insurance costs.
Reflecting on Safety Score 2.0
The introduction of Safety Score 2.0, almost one year ago to the day, marked a significant milestone, adding new safety factors like Excessive Speeding and Unbuckled Driving to Tesla's driving assessment tool. These factors, alongside the updated Late Night Driving metric and existing metrics like Hard Braking and Aggressive Turning, leverage Tesla's vast fleet data to encourage safer driving habits.
Tesla's Safety Score, evolving through versions from 1.0 to the current 2.1, serves as a personalized driving coach. Assessing driving behavior against a set of safety factors provides drivers with actionable feedback to improve their habits. This enhances road safety and offers the potential for lower insurance premiums, aligning financial incentives with safer driving practices.
The Safety Score's utility extends beyond individual feedback; it aggregates millions of miles of driving data to inform Tesla's safety feature development. This ongoing analysis helps identify trends and patterns in driving behavior, shaping the evolution of vehicle safety features and contributing to Tesla's reputation for producing some of the safest vehicles on the road.
As Tesla continues to refine its Safety Score system, incorporating driver feedback and advancing technology, the dialogue between the company and its community is vital. The adjustments in Safety Score 2.1, especially the revised Late-Night Driving metric, reflect a positive step towards balancing safety assessments with real-world driving experiences. Meanwhile, the ongoing discussions about FCW sensitivity underscore the importance of continuous improvement and innovation in vehicle safety systems.
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.
