Tesla's Dashcam now provides more informative badges
Not a Tesla App
With Tesla's holiday update, version 2023.44.30 and above, Tesla has made several performance improvements to video-heavy features such as the Dashcam Viewer and Tesla Theater apps.
It's not clear whether the improvements are only for Intel Atom entertainment units or if the changes are merely more noticeable on the slower processor, but video-related apps are now faster and more responsive.
Dashcam / Sentry Mode Viewer
There have been performance improvements to Tesla's video apps such as the Dashcam Viewer
Not a Tesla App
When viewing Dashcam footage through the vehicle's built-in viewer, you'll immediately notice that video appears to load faster and play smoother.
When using the progress bar to scrub through footage, you'll also notice a big improvement in responsiveness and less "jumpy" video.
These changes may be in part due to a new open-source Shaka player Tesla implemented in the update leading up to the holiday release. The new Javascript-based player supports a wide array of audio and video codecs that Tesla may be leveraging to improve performance.
Dashcam Icons
Along with improvements to the Dashcam Viewer, Tesla also added more informative icons to the Dashcam. If you commonly use the Dashcam app in your launcher, you'll appreciate these additional badges that provide more information on the state of the Dashcam.
The dashcam icon will now display these states:
Saving / Loading: This icon features a gray badge with arrows letting you know the Dashcam is saving or retrieving footage to the USB drive.
Saved Successfully: After successfully saving footage to the USB drive, a green checkmark badge will now briefly appear on the dashcam icon.
Error / Not Recording: If there is an error with your dashcam, USB drive or recording is turned off, there will be a gray badge with an 'X' that signifies that the dashcam is not actively recording.
Paused: A red pause badge shows up on the dashcam's icon if the dashcam is temporarily not recording, like if the Dashcam Viewer is actively being used.
Tesla Theater
Similar to the improvements to the Dashcam Viewer, Tesla Theater is also seeing significant performance improvements while browsing and watching content.
The improvements are especially noticeable when scrolling through content, watching YouTube, or minimizing Tesla Theater. In general, the interface is smoother and fewer frames are dropped.
These improvements are significant for Intel Atom entertainment units (MCU 2), as these apps could sometimes be frustrating to use due to them being unresponsive or jumping around.
We're not sure if the Shaka media player offers performance improvements over the previous player, whether Tesla switched to a less CPU-intensive video codec for MCU 2 owners, or if there are other underlying changes, but the difference to video apps is very much noticeable and appreciated.

Tesla’s Cybertruck has officially earned a 5-Star Safety Rating from the NHTSA—an impressive achievement given the vehicle’s design. The achievement demonstrates Tesla’s engineering prowess. As one engineer points out, it wasn’t an easy feat.
Interestingly, the NHTSA only recently disclosed the results, despite the crash tests being completed a while ago. According to Lars Moravy, Tesla’s VP of Vehicle Engineering, the team had been aware of the 5-star rating for quite some time. While the reason for the delay remains unclear, now that the results are public, Tesla’s engineers can finally share how they achieved the rating.
Crumple Zones
Wes Morril, the Cybertruck’s Lead Engineer, wrote about the crash test video on X recently, addressing the claims that the Cybertruck doesn’t have a crumple zone. He also posted a side-by-side video (below) of the engineering analysis and the crash test itself.
Engineered Crash Safety
There’s a lot of engineering precision at play when a Cybertruck is involved in a crash. Unlike traditional crash structures that rely on crash cans and collapse points, the Cybertruck’s front gigacasting is designed to absorb and redirect impact forces in a highly controlled manner.
It all starts with the bumper beam, which crushes within the first few milliseconds of a high-speed impact. At the same time, the vehicle’s sensors rapidly analyze the crash dynamics and determine the optimal deployment of safety restraints, including airbags and seat belt pre-tensioners. These split-second actions are crucial in keeping occupants safe.
As the crash progresses, the vehicle’s structure deforms in a carefully engineered sequence. The drive unit cradle bends, directing the solid drive unit downward and out of the way, allowing the gigacasting to begin absorbing impact forces.
The casting crushes cell by cell, methodically dissipating energy in a controlled manner. This gradual deceleration reduces the g-forces transferred to occupants, making the crash much less severe. As the gigacast begins crushing, the safety restraints are deployed.
As Wes points out in his post - you can see how accurate the virtual analysis and modeling were. The video shows the simulated crash side by side with the real-life crash test and they’re almost identical. All that virtual testing helps provide feedback into the loop to design a better and safer system - one that is uniquely different than any other vehicle on the road.
All the armchair experts claimed the Cybertruck has no crumple zone and I get it, the proportions seem impossible. It was a tough one and there is a lot of engineering that went into it. Let me break it down for you:
Tesla has pioneered the use of single-piece castings for the front and rear sections of their vehicles, thanks to its innovative Gigapress process. Many automakers are now following suit, as this approach allows the crash structure to be integrated directly into the casting.
This makes the castings not only safer but also easier to manufacture in a single step, reducing costs and improving repairability. For example, replacing the entire rear frame of a Cybertruck is estimated to cost under $10,000 USD, with most of the expense coming from labor, according to estimates shared on X after high-speed rear collisions.
These insights come from Sandy Munro’s interview (posted below) with Lars Moravy, Tesla’s VP of Vehicle Engineering, highlighting how these advancements contribute to the improvements in Tesla’s latest vehicles, including the New Model Y.
However, with the new Model Y, Tesla has decided to go a different route and eliminated the front gigacast.
No Front Casting
Tesla’s factories aren’t equipped to produce both front and rear castings for the Model Y. Only Giga Texas and Giga Berlin used structural battery packs, but these were quickly phased out due to the underwhelming performance of the first-generation 4680 battery.
Tesla has gone back to building a common body across the globe, increasing part interchangeability and reducing supply chain complexity across the four factories that produce the Model Y. They’ve instead improved and reduced the number of unique parts up front to help simplify assembly and repair.
There is still potential for Tesla to switch back to using a front and rear casting - especially with their innovative unboxed assembly method. However, that will also require Tesla to begin using a structural battery pack again, which could potentially happen in the future with new battery technology.
Rear Casting Improvements
The rear casting has been completely redesigned, shedding 7 kg (15.4 lbs) and cutting machining time in half. Originally weighing around 67 kg (147 lbs), the new casting is now approximately 60 kg (132 lbs).
This 15% weight reduction improves both vehicle dynamics and range while also increasing the rear structure’s stiffness, reducing body flex during maneuvers.
Tesla leveraged its in-house fluid dynamics software to optimize the design, resulting in castings that resemble organic structures in some areas and flowing river patterns in others. Additionally, manufacturing efficiency has dramatically improved—the casting process, which originally took 180 seconds per part, has been reduced to just 75 seconds, a nearly 60% time reduction per unit.

Tesla’s new casting method incorporates conformal cooling, which cools the die directly within the gigapress. Tesla has been refining the die-casting machines and collaborating with manufacturers to improve the gigapress process.
In 2023, Tesla patented a thermal control unit for the casting process. This system uses real-time temperature analysis and precise mixing of metal streams to optimize casting quality. SETI Park, which covers Tesla’s manufacturing patents on X, offers a great series for those interested in learning more.
The new system allows Tesla to control the flow of cooling liquid, precisely directing water to different parts of the die, cooling them at varying rates. This enables faster material flow and quicker cooling, improving both dimensional stability and the speed of removing the part from the press for the next stage.
With these new process improvements, Tesla now rolls out a new Model Y at Giga Berlin, Giga Texas, and Fremont every 43 seconds—an astounding achievement in auto manufacturing. Meanwhile, Giga Shanghai operates two Model Y lines, delivering a completed vehicle every 35 seconds.
