Tesla has finally taken the training wheels off, well, almost. After years of including the word “Beta” every time Full Self-Driving is mentioned, the company is now going with FSD (Supervised). Is it just a rebrand? Maybe, but there is no doubt that there is a significant upgrade from the previous versions of FSD Beta, and it certainly requires more than just a number upgrade, but a full freshening up of the name.
The Significance of "Supervised"
The latest update came with a message to the inbox on the Tesla app, which was highly anti-climatic for those waiting for a Cybertruck message. However, this software update might be as groundbreaking as the Cybertruck in the auto sector.
The transition to FSD (Supervised) acknowledges the current state of Tesla's autonomous technology—it's incredibly advanced and offers significant safety improvements, yet just like before, it still requires driver oversight. This change is a nod to the regulatory landscape and Tesla's cautious approach to autonomy, ensuring drivers remain engaged and responsible while utilizing the system.
Updated Safety Stats Tell the Story
Tesla's FSD technology has made commendable strides in enhancing vehicle safety, as evidenced by the latest statistics. With Autopilot engaged, Tesla vehicles report one crash per 5.39 million miles driven, starkly contrasting with the national average of one crash per 670,000 miles. This positions Teslas on Autopilot as approximately 8.04 times safer than the average US driver. Even without Autopilot, Teslas are about 1.49 times safer. These figures underscore the substantial safety benefits of Tesla's technology on the road, though it hasn't yet reached the ambitious "10 times safer" goal outlined in Tesla's Master Plan Part Deux.
V12.4 is another big jump in capabilities.
Our constraint in training compute is much improved.
The industry has taken note of Tesla's advancements. Michael Dell's commendation of FSD v12.3 as resembling human-like driving capabilities highlights Tesla's progress in refining its autonomous driving features. Elon Musk's response, teasing the release of FSD v12.4, suggests that Tesla is on the brink of further breakthroughs. Musk's mention of overcoming AI training compute constraints indicates that Tesla's pace of development is set to accelerate, promising even more sophisticated autonomous driving capabilities in the near future.
Conclusion
Tesla's update from FSD Beta to FSD (Supervised) is more than a semantic shift—it reflects its safety and autonomous driving technology advancements. By emphasizing the supervised nature of its current FSD system, Tesla is navigating the complex balance between innovation, safety, and regulatory compliance. With FSD v12.4 on the horizon, Tesla continues to drive toward autonomous driving and a safer future on roadways.

Tesla’s vehicles all have a built in Service Mode, where you can find working diagrams of anything from the HVAC system, low or high voltage systems, your power steering, or infotainment. All of this is included on-vehicle, and doesn’t require a third-party tool or subscription.
Of course, if you need more information, Tesla does offer Toolbox3, a fairly inexpensive subscription package that can be downloaded onto any laptop and connected to any Tesla - without the hassle of needing a special manufacturer-specific OBD tool.
Thanks to John Kelly for finding this. Let’s dig into it.
48V LVCS Connector Reference
Cybertruck runs on a 48V architecture, called LVCS, or Low-Voltage Connector Standard. They recently launched this standard to the rest of the automotive industry, in hopes of promoting standardization and progress.
48V and LVCS offer Tesla the unprecedented ability to optimize the wiring inside Cybertruck and future vehicles, massively reducing the complexity and cost - and also ensuring that everything within the vehicle is networked. That networking means that you can also debug the Cybertruck’s wiring from within the vehicle - without needing to disassemble the entire thing.

The Wiring Service Diagram offers the ability to search for particular connectors, and also see where the wiring runs originate and terminate. And that’s not all - you’re also able to pull up the pinouts, wire colors, and harness connections to see everywhere that specific connector brings data, power, or anything else to.

This is an fantastic update, and enables anyone, including a DIY home mechanic, to be able to figure out exactly what might be wrong with a particular system, as well as how to potentially correct it. In addition, all of this data is freely available within the vehicle, and nothing else is required to be able to access it other than sitting down and entering Service Mode Plus.
How to Access It
For this particular interface, you’ll need to access Tesla’s Service Mode Plus, which means you’ll need a subscription to Toolbox 3, Tesla’s Service Software. We won’t walk you through that procedure here, as we recommend you review Tesla’s Service Manuals before jumping in.
Assuming you know what you’re doing, once TB3 is setup and connected to the vehicle, you can enter Service Mode Plus from the TB3 primary menu, and then navigate your way to the Low Voltage section. The Connector Reference Tool is its own sub-heading, and the search tool to look for particular connectors is in the top right.
Tesla has recently committed new code to its Light Show Github repository that reveals several additional Lightshow features and shares specifications for others.
Tesla hosts the software for building Lightshows on GitHub, an open-source code repository. The new code was added five days ago, but given that this is a change to the actual software and not an on-vehicle change, we’re not sure whether the features below will be available for immediate use or will be available in a future software update.
Up to Four-Hour Long Light Shows
The feature update is pretty extensive and, for the most part, is focused on the Cybertruck and Model 3 Highland, but also features changes for other Tesla models.
There’s one general change, which now lets you create Light Shows that are up to four hours in length — yes, that’s really long. In the Holiday update, Tesla mentioned that Light Shows can now be longer, but this recent commit makes it seem like Tesla is essentially removing the limit of how long a Light Show can be.
Front & Rear Light Bars
On the outside of the Cybertruck, you’ll now be able to control the front light bar, but what’s even better is that you can control each of the 60 LEDs individually. The rear light bar is seeing similar improvements, letting you control each of the 52 LEDs individually.
This feature alone is going to create some amazing Light Shows, anything from which has 60 individually configurable LEDs each. The rear light bar has 52 individually controllable LEDs as well.
This alone is going to inspire some really creative designs, such as a Knight Rider-like animation as seen on Rivian.
These are, of course, locked to just white for the front light bar and red for the rear, but Lightshow designers will be able to configure how bright each individual LED is and feather them up and down in brightness.
As we saw in the absolutely epic Tesla octa-truck Lightshow, the off-road lightbar is also controllable on vehicles that have it equipped. For now, that’ll just be Foundation-Series Cybertrucks, but the lightbar has been confirmed to be compatible with the non-Foundation-Series vehicles once it arrives in the Tesla shop later this year.
The off-road lightbar has six segments - two side-facing ditch lights and four forward-facing lights. Although you won’t be able to address individual LEDs here, you’ll be able to control each segment (six total) and brightness.
This feature was added as part of the Holiday update, so it should be available for all vehicles on 2024.44.25 and higher.
Center Display Color
Over on the interior side, designers will get full RGB control for the center display. Even when viewing the light show from the exterior of the vehicle, the center display will light up the interior in any color of your choice, letting you add festive colors to your Light Shows.
The interior display is also available on the Holiday update and is available for all vehicles, including legacy Model S and Model X vehicles that support Light Shows.
Ambient Lighting
This one has been a long time coming, but you’ll finally be able to control the vehicle’s ambient lighting feature on the Cybertruck and new Model 3. The accent lights are split into five segments and are all controllable RGB, so you can set each section to a different color if you want. The sections include center front, left and right front, and left and right rear.
These are some massive additions to Tesla’s Light Show feature, and they’re arguably some of the best. The individually controllable LEDs in the light bars and the ability to choose colors for the first time will undoubtedly create some of the best Light Shows we’ve ever seen.
Unfortunately, Christmas is behind us now, but we’re sure developers will find other holidays that take advantage of colors, such as Independence Day.
Light Shows bring the Tesla community together, and they’re one of the most distinctive Tesla features. Enjoy the awesome Christmas Light Show compilation below. Thanks to Rhys Samson for sharing these Light Show changes with us.
