Following initial reactions to Tesla's 2023 Holiday Update, Elon Musk acknowledged the need for improvement, stating, "We need to step up our game." His post on X was followed by Tesla shedding more light on the Holiday Update than what was in the initial leak.

Call me old, but I remember a time when you bought a car, and that was it; the dealer and manufacturer didn’t give you anything else. So is the Tesla community acting a little bit spoiled here? Absolutely. But it also shows how high Tesla has set the bar with its previous Holiday Updates.

Initial Release and Feedback

The initial release of the 2023 Holiday Update, version 2023.44.25, received mixed reactions from the Tesla community, with some owners expressing disappointment over the lack of groundbreaking new features. But the newly announced features may serve as better stocking stuffers.

The initial rollout included something owners have been asking for, the blind spot monitor. The camera that turns on when you change lanes will now have a red color added if there is something in your blind spot. It’s not clear whether it will be accompanied by a tone.

Here are other features in the leaked update that are being tested by employees:

Navigation and Safety Features: Including symbols for speed cameras, stop signs, and traffic lights in navigation, and the automatic 911 call feature in case of an accident.

Trip Planning via Tesla Mobile App: Allowing for more detailed trip planning, including multiple stops and charging points.

Apple Podcasts Integration: Allowing users to sync with Apple devices for a seamless podcast experience, directly addressing the demand for a richer in-car entertainment system.

New Games and Enhancements: The update brought updates to Tesla Arcade, with Beach Buggy Racing and Polytopia Diplomacy updates, as well as the Vampire Survivors Chilling update.

Light Show Improvements: There’s a new light show that’s included with your vehicle. You’ll also be able to upload several light shows on a single USB drive and pick one from the vehicle, instead of having to use multiple USB drives, one for each light show.

More Live Sentry Mode Cameras: You will now be able to view the B-pillar cameras directly from the Tesla app. This brings the number of viewable cameras in the app up to seven. The only ones still missing are the alternative front-facing cameras that are telephoto and wide-angle, which wouldn’t bring much additional value. Although the B-pillars are viewable in the app with this update, they will still not be used to record during Dashcam or Sentry Mode events.

High-Fidelity Park Assist

In response to the feedback and Musk's statement, Tesla unveiled additional features in its updated holiday update, including an improved park assist with enhanced visualizations.

This feature provides a 3D reconstruction of the vehicle's surroundings while parking, akin to a 360-degree camera system found in other high-end vehicles. The system is clearly leveraging improvements to Tesla Vision to create the surrounding environment, such as cars, pillars and walls.

This feature also appears to change the color of objects depending on how close they are to your vehicle. In the image we can see the pillars are orange, but if we look closer, the object behind the vehicle is also orange near the bottom. The sides of the vehicles next to the Tesla also have a slight hint of orange, indicating their proximity.

However, it looks like this feature may be even better than it initially looks. The vehicles in the image aren’t just predefined 3D models that Tesla created, like the ones used in Autopilot visualizations. These models appear to be dynamically created using vision, so that no two cars would look alike, much more similar to what LiDar is able to achieve. The visualization provides a true representation of the environment around the vehicle. You can see that each vehicle is made up from layers and have blurred edges toward the rear, where the camera would have a hard time seeing.

These 3D models could be a sneak peek at the future of FSD visualizations.

High-Fidelity Park Assist Requirements

A big question on everyone’s mind is who will receive this new park assist feature. Tesla didn’t address this in their post on X besides providing a disclaimer that the features in the holiday release are subject to model and region availability. Tesla often likes to test features in select markets before making them available everywhere. It’s hard to say whether that will be the case here. There likely aren’t any legal ramifications around providing visualizations, so that’s a good sign that this feature will be available in most regions, either in the holiday update, or soon afterward.

However, there are still questions around which models or hardware will be required. From the image shared, we can see it’s offered on a Model Y, removing any speculation of it possibly requiring the HD radar in the new Model S/X. We also don’t think it will require FSD hardware 4.0, so the remaining questions are whether it requires MCU 3, or the FSD package.

Given that Tesla is calling this Park Assist, it doesn’t appear to be linked to Auto Park, which is a FSD package feature. When Tesla rolled out visual and audio alerts for vehicles without ultrasonic sensors, it called the feature Park Assist, and that was available to all owners.

Whether this improved Park Assist feature requires a vehicle with MCU 3 will depend on the level of processing power required. It’ll certainly require more than the current visualizations given that its building the scene in real-time, so we’re hopeful that it’ll work on MCU 2 vehicles too, but we just don’t have enough information right now to make the call.

Custom Lock Sounds

Tesla also announced a fun and whimsical feature that allows owners to customize the lock sound of their Tesla. No longer will you need to listen to the car’s horn when it locks as you walk away. Now you’ll be able to customize the lock sound of the vehicle. Tesla is including several options, including sounds like a screaming goat, a jingle, a rubber ducky, a quack sound, an old school horn and applause. However, you’ll also be able to upload your own file to create a truly unique experience.

You can pick anything, from a bird’s tweet to a favorite video game sound. You’ll only be limited by the maximum upload file size, which according to a Tesla engineer, is a 1MB file in WAV format, which is roughly about 40 seconds at good quality.

This feature is possible due to the vehicle’s external pedestrian warning speaker. So if you have Tesla’s Boombox feature or your vehicle makes a sound when traveling under 20 MPH, then you should receive this fun enhancement.

Rear Seat Audio and Gaming

Enhancing the Tesla Arcade experience, passengers in the rear seats can now play games on the rear touchscreen. This feature, especially when paired with Tesla Arcade’s compatibility with PS4, PS5, Xbox Controllers, and rear-screen Bluetooth Headsets, is a welcome addition for families and long trips.

Much like the new Model 3, which received rear audio over Bluetooth support in the 2023.38 update, the new Model S and Model X will also receive this ability in the holiday update.

New Game - Castle Doombad

Tesla announced one other feature in the 2023 holiday update that hadn’t been previously leaked, and that’s a new game called Castle Doombad. Castle Doombad is a single player tower defense, puzzle-like game that’s currently available on iOS and Android, but has an upcoming release on PC and the Nintendo Switch. This game is expected to require MCU 3.

Release Timeline

The rollout of the 2023 Holiday Update is expected to follow a similar timeline to last year. Tesla announced that the update will roll out starting next week. However, it’s not clear whether this will also include FSD Beta testers that are on a 2023.27 update.

Looking back at the 2022 Holiday Update, it started on December 13 and took about a week to get to the entire fleet.

Speculation on Future Features

Like a spoiled child on Christmas morning, Tesla owners still ask, “Is that it?” Well… possibly, but there may be more to look forward to early next year as Tesla builds off of the new High-Fidelity Park Assist feature.

Advanced Smart Summon: Upgrading the Smart Summon feature to be more intuitive and efficient, especially in complex parking scenarios.

Reverse Summon / Park Seek: What happened to Tesla dropping its passengers and driver off at the location and then finding a parking spot on its own?

Enhanced FSD Visualizations: Expanding the Full Self-Driving visualizations to more regions or models or completely recreating the FSD visualizations using the same neural networks Tesla is using for the High-Fidelity Park Assist feature.

Tesla Smoking While Supercharging? A Look at What's Actually Happening

By Karan Singh
Hot_Engineering3140 on Reddit

Winter is here, and temperatures are dropping, so one of the most common Tesla questions is about to resurface.

If you’ve landed here after frantically searching about “smoke” coming from your Tesla while Supercharging, take a deep breath—it’s completely normal.

Tesla Smoking While Charging

If you’re Supercharging in freezing weather—even with preconditioning—you might notice steam rising from your Tesla. But rest assured, your car isn’t smoking.

Your Tesla’s heat pump is hard at work warming both the cabin and battery to keep you comfortable and ensure optimal charging temperatures. Over time, condensation and ice build-up in the heat exchanger coils.

Why Does It Happen?

When you reach a Supercharger with your vehicle, the heat pump is still running hot, but without the cold air from driving to keep the heat exchanger coils cool, the ice and condensation quickly start to evaporate—creating what looks like smoke.

Since this typically happens near the front of the vehicle, where a car would traditionally have an engine, new vehicle owners can be startled by the discovery. However, rest assured that it’s just water vapor and it’s completely normal in cold weather.

In fact, this behavior can be experienced in any EV with a heat pump in cold climates. So, if you saw steam coming out of your vehicle and panicked, don’t worry—you’re not alone.

Now that you know what’s happening, go ahead and Supercharge with confidence.

Tesla Improves YouTube App With Smoother Playback

By Karan Singh
Not a Tesla App

Tesla made a lot of improvements in the 2024 Holiday Update, including more than 15 undocumented improvements that were included in the release. One of these was a stealthy performance improvement to the YouTube app.

Several people have mentioned they’ve seen improved performance on YouTube since this year’s Holiday Update - and there’s an interesting reason why.

YouTube Improvements

The improved YouTube performance in Tesla vehicles comes from an unexpected source—Tesla actually rolled back support for YouTube’s newer AV1 video encoding. Instead, vehicles now default to the older VP9 encoding standard.

While AV1 is highly efficient in terms of bandwidth, it requires considerably more processing power to decode and display videos. VP9, on the other hand, is less computationally demanding but uses more bandwidth to achieve the same video quality. This trade-off means smoother playback and better overall performance, even if it comes at the cost of slightly higher data usage.

Intel Inside

The VP9 video codec that the YouTube app is now using is much easier to decode, making it less taxing on the vehicle’s processor. This change is particularly beneficial for Tesla vehicles with Intel processors, which previously struggled to stream video at just 720p. When using AV1, these vehicles often experienced stuttering, sometimes forcing the YouTube app to automatically downgrade playback to 480p.

With this update, Intel-based Teslas should now be able to stream at 1080p smoothly. Streaming at 1440p is also possible, although occasional stutters still occur as the system keeps up with the decoding process.

Intel-based vehicles are the big winners with this change, but this appears to affect AMD Ryzen-based infotainment units as well, providing even smoother playback.

Chromium Web App

Tesla’s Theater apps aren’t native applications; instead, they run as chromeless web apps, leveraging the open-source browser built into Teslas known as Chromium (the open-source version of Chrome). Although this works quite well, there is a severe limitation - Chromium hardware acceleration isn’t supported on Linux, the operating system Tesla uses for their OS.

As a result, Tesla vehicles rely on software decoding instead of hardware decoding, which would otherwise handle video playback far more efficiently. A potential solution could be for Tesla to transition away from Chromium-based web apps in favor of a Mozilla Firefox-based browser, as Firefox does support hardware acceleration on Linux. This switch could also open the door to better streaming performance and the possibility of expanding Tesla’s in-car entertainment options.

However, Tesla’s choice of Chromium likely stems from Digital Rights Management (DRM) requirements for streaming services like Disney+ and Netflix, which rely on DRM-enabled playback. Firefox on Linux has had inconsistent support for DRM due to codec availability and variations in operating system versions.

We’re hopeful that Tesla will either adopt Firefox or develop a fully native application to improve video streaming, rather than continuing with the current web-based Tesla Theater. This shift could also pave the way for additional in-car applications built on Tesla’s native Linux environment—perhaps even reviving the long-rumored Tesla App Store.

Regardless, this update is a welcome improvement, particularly for YouTube, which remains one of the most widely used Theater Mode apps due to its accessibility, free content, and mix of short and long-form videos. It remains to be seen whether similar improvements are made for Netflix, Disney+, or other streaming platforms.

If you’ve noticed improved performance in Theater Mode, now you know why.
