Tesla rolls out 2020 Holiday Update: New Driving Visualizations, Supercharger Display Improvements and more (Release Notes)
Tesla is beginning to roll out its highly anticipated over-the-air 2020 ‘Holiday Update’ that includes new driving visualizations for Full Self-Driving, new games, and an improved display for Supercharger and Vehicle Information, among others.
The following are some of the most notable aspects of Tesla’s 2020 holiday update as part of Firmware 2020.48.25.
Arguably, the Tesla community fan-favorite comes in the form of a new “Boombox” feature that enables the much-talked-about Snake Jazz and Goat easter eggs.
Vehicle Information
Tesla has removed the Tesla “T” from the top menu, which provides better use of the touchscreen display’s real estate. Display improvements can be seen throughout much of the 2020 Tesla Holiday Update.
“The Tesla ‘T’ has been removed from the top status bar. Tap Controls > Software for the same information.”
Release Notes Improvements
Release notes can be accessed under the controls menu. Each feature has been itemized into a tabular left menu that provides quick access to the description for previous and current features.
“Release notes now include improved browsing and access. To view current and previous release notes, tap controls > Software > Release Notes.”
Driving Visualization Improvements
Improved driving visualizations to support Full Self-Driving capabilities take center stage in this year’s highly-anticipated Tesla Holiday Software Update.
“The driving visualization has been refreshed and now offers a larger visualization to allow drivers to view more details of the road surroundings. The next turn will now appear above the visualization if the navigation turn list is covered by another app.
Additionally, select items have slightly moved but will continue to look and behave the same. Some notable differences include the following:
- Quick access to the backup camera and wipers has moved to the bottom bar.
- Indicator lights have been moved to the side of the touchscreen.
- Autopilot set speed, Autopilot availability, and detected speed limit are now displayed next to the driving speed.”
Scheduled Departure Improvements
A refreshed look for the “Scheduled Departure” feature, previously known as “Smart Preconditioning” and released in October 2019, puts more emphasis on a simple design for easier control of charging costs and interior comfort when ready to drive. Tesla notes that Scheduled Departure can operate even when the vehicle is unplugged.
The previous language of not being functional below a 20% battery state of charge is no longer visible.
“Schedule departure can now precondition your battery and cabin even when your car is unplugged. To account for different utility rate plans, you can now set the time when your off-peak rates end to save on charging costs. To access, tap SCHEDULE from the climate control or charging panel when parked.”
Supercharger Display Improvements
Real-time Supercharger occupancy information was rolled out nearly 4 years ago (see version 1.0), and since then Tesla has continued to make user experience improvements for drivers looking to quickly access information from their touchscreen for distraction-free driving. This includes the ability to see available charging stalls at-a-glance and without the need for unnecessary taps of the touchscreen.
“Supercharger pins on your touchscreen will now display the number of available stalls at charging sites. Quickly search for nearby amenities by tapping an amenity icon on the Supercharger popup display.”
Tesla has replaced the iconic Tesla Supercharger lightning bolt icon with a number that denotes the number of currently available chargers at the location.
Emissions Testing Mode Improvements
How can one improve upon Tesla’s famed “Emissions Testing Mode”, better known as “Fart Mode”? Fart at strangers.
“Emissions Testing Mode can be used outside the car. To setup, select your desired sound and place the cushion on the external speaker. When ready, play selected sound by pressing the left scroll wheel button or using the turn signal. To access, tap the Application Launcher > Toybox > Emissions Testing Mode.”
Boombox
Elon Musk has made good on his promise to give Tesla owners the ability to entertain crowds and passersby through honking-fart and goat sounds, plus more.

In addition to several new out-of-the-box sound clips that blast out of Tesla’s exterior speaker, the latest Boombox feature enables the upload of five custom sounds.
“Turn your car into a boombox and entertain a crowd with your media player when parked. You can also customize the sound your car makes when you press the horn, drive the car or when your car is moving with Summon. Select an option from the dropdown menu or insert your own USB device and save up to five custom sounds.”
Tesla Arcade: New Games
Tesla launched a series of new games for its Tesla Arcade collection, including The Battle of Polytopia, Cat Quest, Solitaire, and Boombox.

- Cat Quest
- Solitaire
Last month, Elon Musk teased the community when he tweeted about this year’s holiday software update. Musk hinted that 2020’s holiday update would be “lit.” He also mentioned that the highly-anticipated update would include features that customers wanted, and some that they didn’t even know they wanted.
Last year, Elon Musk and the Tesla team outdid themselves with the holiday software update. Tesla’s 2019 holiday update included a sneak preview of the company’s Full Self Driving suite, TRAX v0.1, and introduced new games to the arcade, such as Stardew Valley and Lost Backgammon.

Elon Musk says he’s open to powering Apple’s Siri with xAI’s Grok
Siri, one of the first intelligent AI assistants in the market, has become widely outdated and outperformed by rivals over the years.
Elon Musk says he’s willing to help Apple overhaul Siri by integrating xAI’s Grok 4.1, igniting widespread excitement and speculations about a potential collaboration between the two tech giants.
Siri, one of the first intelligent AI assistants in the market, has become widely outdated and outperformed by rivals over the years.
Musk open to an Apple collaboration
Musk’s willingness to team up with Apple surfaced after an X user suggested replacing Siri with Grok 4.1 to modernize the AI assistant. The original post criticized Siri’s limitations and urged Apple to adopt a more advanced AI system. “It’s time for Apple to team up with xAI and actually fix Siri. Replace that outdated, painfully dumb assistant with Grok 4.1. Siri deserves to be Superintelligent,” the X user wrote.
Musk quoted the post, responding with, “I’m down.” Musk’s comment quickly attracted a lot of attention among X’s users, many of whom noted that a Grok update to Siri would be appreciated because Apple’s AI assistant has legitimately become terrible in recent years. Others also noted that Grok, together with Apple’s potential integration of Starlink connectivity, would make iPhones even more compelling.
Grok promises major Siri upgrades
The enthusiasm stems largely from Grok 4.1’s technical strengths, which include stronger reasoning and improved creative output. xAI also designed the model to reduce hallucinations, as noted in a Reality Tea report. Supporters believe these improvements could address Apple’s reported challenges developing its own advanced AI systems, giving Siri the upgrade many users have waited years for.
Reactions ranged from humorous to hopeful, with some users joking that Siri would finally “wake up with a personality” if paired with Grok. Siri, after all, was a trailblazer in voice assistants, but it is currently dominated by rivals in terms of features and capabilities. Grok could change that, provided that Apple is willing to collaborate with Elon Musk’s xAI.

Tesla’s top-rated Supercharger Network becomes Stellantis’ new key EV asset
The rollout begins in North America early next year before expanding to Japan and South Korea in 2027.
Stellantis will adopt Tesla’s North American Charging System (NACS) across select battery-electric vehicles starting in 2026, giving customers access to more than 28,000 Tesla Superchargers across five countries.
The rollout begins in North America early next year before expanding to Japan and South Korea in 2027, significantly boosting public fast-charging access for Jeep, Dodge, and other Stellantis brands. The move marks one of Stellantis’ largest infrastructure expansions to date.
Stellantis unlocks NACS access
Beginning in early 2026, Stellantis BEVs, including models like the Jeep Wagoneer S and Dodge Charger Daytona, will gain access to Tesla’s Supercharger network across North America. The integration will extend to Japan and South Korea in 2027, with the 2026 Jeep Recon and additional next-generation BEVs joining the list as compatibility expands. Stellantis stated that details on adapters and network onboarding for current models will be released closer to launch, as noted in a press release.
The company emphasizes that adopting NACS aligns with a broader strategy to give customers greater freedom of choice when charging, especially as infrastructure availability becomes a deciding factor for EV buyers. With access to thousands of high-speed stations, Stellantis aims to reduce range anxiety and improve long-distance travel convenience across its global portfolio.
Tesla Supercharger network proves its value
Stellantis’ move also comes as Tesla’s Supercharger system continues to earn top rankings for reliability and user experience. In the 2025 Zapmap survey, drawn from nearly 4,000 BEV drivers across the UK, Tesla Superchargers were named the Best Large EV Charging Network for the second year in a row. The study measured reliability, ease of use, and payment experience across the country’s public charging landscape.
Tesla’s UK network now includes 1,115 open Supercharger devices at 97 public locations, representing roughly 54% of its total footprint and marking a 40% increase in public availability since late 2024. Zapmap highlighted the Supercharger network’s consistently lower pricing compared to other rapid and ultra-rapid providers, alongside its strong uptime and streamlined user experience. These performance metrics further reinforce the value of Stellantis’ decision to integrate NACS across major markets.

Tesla FSD and Robotaxis are making people aware how bad human drivers are
These observations really show that Tesla’s focus on autonomy would result in safer roads for everyone.
Tesla FSD and the Robotaxi network are becoming so good in their self-driving performance, they are starting to highlight just how bad humans really are at driving.
This could be seen in several observations from the electric vehicle community.
Robotaxis are better than Uber, actually
Tesla’s Robotaxi service is only available in Austin and the Bay Area for now, but those who have used the service have generally been appreciative of its capabilities and performance. Some Robotaxi customers have observed that the service is simply so much more affordable than Uber, and its driving is actually really good.
One veteran Tesla owner, @BLKMDL3, recently noted that the Robotaxi service has become better than Uber simply because FSD now drives better than some human drivers. Apart from the fact that Robotaxis allow riders to easily sync their phones to the rear display, the vehicles generally provide a significantly more comfortable ride than their manually-driven counterparts from Uber.
FSD is changing the narrative, one ride at a time
It appears that FSD V14 really is something special. The update has received wide acclaim from users since it was released, and the positive reactions are still coming. This was highlighted in a recent post from Tesla owner Travis Nicolette, who shared a recent experience with FSD. As per the Tesla owner, he was quite surprised as his car was able to accomplish a U-turn in a way that exceeded human drivers.
Yet another example of FSD’s smooth and safe driving was showcased in a recent video, which showed a safety monitor of a Bay Area Robotaxi falling asleep in the driver’s seat. In any other car, a driver falling asleep at the wheel could easily result in a grave accident, but thanks to FSD, both the safety monitor and the passengers remained safe.
These observations, if any, really show that Tesla’s focus on autonomy would result in safer roads for everyone. As per the IIHS, there were 40,901 deaths from motor vehicle crashes in the United States in 2023. The NHTSA also estimated that in 2017, 91,000 police-reported crashes involved drowsy drivers. These crashes led to an estimated 50,000 people injured and 800 deaths. FSD could lower all these tragic statistics by a notable margin.
