Tesla has added a true blind spot indicator to the new Model 3
Not a Tesla App
Tesla has finally introduced a blind spot indicator, more than 20 years after the technology was first introduced, but only in the new Model 3. This feature, commonplace in contemporary vehicles and initially integrated by Volvo back in 2001, raises questions on why the innovative company lagged in adopting such a fundamental safety feature, and yet the version it did release seems a little flawed.
Odd Placement and Missing a Vital Element
The implementation of the blind spot indicator has a peculiar placement - tucked away in the speaker grill of the driver’s door. While this step marks Tesla’s bid to align with a standard safety feature present in other vehicles, it inevitably conjures questions regarding the prudence behind the choice of location. Possibly, a revision in the hardware could have presented an opportunity to explore more ergonomic spots that facilitate easier and quicker reference for the drivers.
Moreover, early reviews and an examination of the European Model 3 owner's manual suggest that the blind spot indicator has only been installed on the driver’s side, which seems nonsensical considering the equal prominence of blind spots on the passenger side. It appears somewhat unbalanced and potentially neglects the safety concerns of changing lanes or turning in the opposite direction.

Tesla Cameras For Blind Spots
Historically, Tesla relied heavily on its Autopilot camera system, providing visualization features that necessitated drivers to glance at the vehicle’s center screen to gauge their blind spots, a system arguably not ideal due to its diversion of the driver's attention from the road. Despite their efforts to improve upon this through the new indicator, whether they've achieved a solution that matches the industry standard set by many other automakers years ago is questionable.
However, it’s undeniable that Tesla has attempted to create a comprehensive blind spot assist system, including features such as an automatic blind spot camera and a blind spot collision warning chime. These add-ons indicate that Tesla aims to offer a multi-faceted assistive system, primarily focusing on auditory and visual screen alerts rather than physical indicators, maintaining its penchant for tech-heavy solutions.
What is clear is that Tesla has responded to a long-standing request, although not with an earth-shattering innovation but with a feature that has been standard for many years in the automotive industry. While the effort is commendable, one cannot overlook that it comes with a shade of playing catch-up and carries with it a slew of questions concerning the execution of the feature in terms of its placement and partial implementation. Perhaps a birds-eye 360 view is next?
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.
