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.

How to use Grok Bot to block spam calls and texts
Musk told users to ask Grok Bot to scrub their phone numbers from spam lists.
Elon Musk has a new use case for Grok Bot, and it is the spam call. On Thursday he replied to an X user named Arash with a short instruction: “Ask your @Grok @Bot to remove your phone number from spam call & text lists!” Arash had said he got tired of the calls, had an AI bot find his number on listing sites and file removal requests, and packaged the process as a free skill for others.
The skill is called Spam-Call Scrubber, which is described to find a phone number on people search sites and data brokers, submits the opt outs, completes the confirmation emails those sites send back, and rechecks on a schedule the user picks. Using it requires the Grok Bot app. The pitch is time saved, since most broker opt outs sit behind separate forms on separate sites.
Ask your @Grok @Bot to remove your phone number from spam call & text lists!

Musk said Grok Bot now gives each bot its own email address, and that it can detect scam emails. On Thursday he also said SpaceX would make users whole if the bot botches a purchase or leaks a card, then told users to shop away from Amazon after the retailer blocked the agent, as Teslarati reported. The terms of service we reviewed at the time put responsibility for what an agent does on the user.
For Tesla owners, Grok Bot is not just a phone app. Tesla brought Grok Bot into its vehicles on September 22, and we argued earlier this week that the Cybercab’s real advantage may be the errands it runs during a ride. Every Cybercab and the rest of the Model Y Robotaxi fleet has it enabled. The more routine tasks like this one become, the more a rider has reason to hand over something personal in the back seat.
The new Spam-Call Scrubber skill can be downloaded for free and works on sites that honor removal requests, while noting that listings can reappear, and illegal robocallers do not check any registry. Whether Spam-Call Scrubber cuts anyone’s call volume is something the first wave of users will find out, and Musk’s endorsement guarantees that wave is coming.
Investor's Corner
Tesla’s flying Roadster just revealed something bigger than the car
Analysts say the Roadster demo puts a Tesla and SpaceX merger back on the table.
The Roadster unveiling near Waco ended Thursday night, and by Friday morning much of the investor reaction had less to do with the car than with who owns the rocket technology inside it.
Wedbush analyst Dan Ives said the event “puts the Tesla/SpaceX relationship on the table in a tangible way,” pointing to the propulsion, pressure vessel and control hardware sitting on a Tesla product. Gene Munster of Deepwater Asset Management called the demo “a ridiculous display of engineering” with “no commercial value” beyond embarrassing traditional automakers, though he said it showed Musk wants the two companies together.
The more specific forecast came a day earlier from Barclays. Analyst Dan Levy told clients a deal could be announced before Tesla’s annual meeting, which must happen by December 6, and that an announcement in late October or early November could make shareholder approval harder. Barclays expects SpaceX to be the buyer in an all stock deal, with Tesla holders receiving SpaceX shares at a premium, based on market values of roughly $2.1 trillion for SpaceX and $1.5 trillion for Tesla. If nothing lands around the meeting, the bank still sees an announcement within 6 to 12 months.
The Roadster demo just added more weight to merger speculations. Tesla’s demo used cold gas thrusters and pressure tanks of the kind SpaceX uses on Falcon 9, and Musk described the car as a collaboration between Tesla and SpaceX engineers, as we mentioned in our breakdown of the three Roadster configurations.
Musk has not publicly addressed a deal since the event, as far as we have seen. His most direct answer remains the one he gave at the All In Summit, when he said that with so much collaboration, “who can imagine what action one might take” without ruling anything out. Ives has held to a 2027 timeline since his March note, and Musk pushed back on the China piece of the speculation when ARK floated a year end announcement in August.
The next test is Tesla’s third quarter earnings call on October 21. However, we recall in July that Musk told analysts, “we can’t talk about combining companies and that kind of thing on an earnings call,” so a clear answer wouldn’t be expected.

How Tesla’s Roadster fan system and thrusters are built to dominate the corners
Tesla’s Roadster uses fans, active wings and cold gas thrusters to create grip at any speed.
Tesla’s new Roadster is best known for flipping through the air in Texas, but the technology that matters most for a race track is the stuff that keeps it on the ground. Tesla’s Roadster page describes a multi-mode fan and ground sealing system that acts as a downforce generator, pulling air out from beneath the car. Tesla says it provides enough suction to hold the vehicle upside down, even when stationary.
That is the key difference from the wings and diffusers on a normal supercar. Conventional aero only makes downforce when the car is moving, and it grows with speed, so a car has the least grip in the slow corners and under hard braking. A fan system makes downforce at any speed. Tesla’s patent, which we covered last year, describes fans and deployable skirts that create sealed or partially sealed regions under the car, with the fans extracting air to lower the pressure and increase grip and stability.
Still processing this … the most unreal thing I’ve seen. https://t.co/HtEuvnkZjY

Tesla pairs that with active wings, a next generation steer by wire system and a Track Mode that lowers the car and changes the suspension, with high downforce and low drag settings for the circuit. To keep weight down, Tesla points to magnesium, titanium and carbon fiber, manual controls and a fixed seat position, which it says lets the car respond to driver inputs almost instantly.

The cold gas thrusters are the other half. On the Thrust version they sit at the rear and Tesla says they take the car from 0 to 60 mph in under 0.9 seconds, while the Rocket version adds perimeter thrusters for forward, upward and lateral rotational movement. Tesla says the all electric actuators make micro adjustments within a fraction of a second.

Musk has been talking about records for years. In June 2019 he said, “We’re going to do things with the new Roadster that are kind of unfair to other cars.” That September, when a follower asked whether the Roadster would beat the Nürburgring production car record, he replied with one word, “Absolutely,” as we reported at the time. In February 2024 he said Tesla had “radically increased the design goals” for the car and that its sub one second 0 to 60 time would be “the least interesting part.”
There are caveats. Tesla has not published a lap time or a verified cornering figure, so the record talk is still a promise rather than a result. Tesla also says the car is not approved for public road use, and the thruster features are limited to the Rocket trim, which is invite only. Fan cars have also been banned or withdrawn before, and getting a sealed underbody to work on a rough public road is a harder problem than on a smooth track. The first real test will be an official lap at a circuit.
