Not a Tesla App
Tesla's 2023.12.1 software update brings various new features and enhancements to its vehicles. One of the most significant updates is the steering wheel customization, specifically for Model 3 and Model Y. The video below shows how easy it is to use and navigate multiple menus.
The left scroll button now has multiple uses, enabling drivers to adjust settings such as brightness and Acceleration Mode and perform actions like toggling the Camera App, opening the glovebox, and saving Dashcam footage. To access these options, long press the left scroll button to display a list of functions and scroll through the list. To choose the default function, go to Controls > Display > Scroll Wheel Function.
Steering Wheel Customization is currently only available for the Model 3 and Model Y, but that may be changing soon.
The Tesla release notes reveal an icon with an upward arrow on the car, suggesting possible future suspension adjustments from the scroll wheel menu — a feature currently exclusive to Model S/X.
New Search Function
The new search function, located under the menu, displays options as you type and offers suggestions for easier access to controls and settings. This should make it easier to adjust specific options, especially if you're unsure which menu they're under.
Points of Interest with Photos and Reviews
When selecting a point of interest or Supercharger location, the updated software now includes photos and reviews to provide users with more information. For example, you can tap on a restaurant and immediately receive information about the menu, pictures and reviews.

There are various enhancements and changes to the UI in this update that Tesla didn't mention in their release notes. For a full list of all those changes, be sure to check our the release notes for update 2023.12.1, where we list all the official release notes along with undocumented changes.
Optional Gear Chimes for Model 3/Y
Gear chimes have been added as an optional feature for Model 3 and Model Y vehicles. Similar to the same noise users hear when activating and deactivating Autopilot, a chime will provide an audible alert when the car is put in drive, park and reverse. This update is expected to extend to Model S/X and is available worldwide.
Spotify Web-based Player and Phone Call Controls
According to @GreenTheOnly, Tesla's Spotify player has transitioned to be a web-based player, similar to Apple Music. It appears that Tesla will be transitioning all music services to leverage their web-based player, allowing quicker development.
In the new Model S/X and Model 3/Y, you'll now also be able to control phone calls from the steering wheel. The left scroll button can be used to answer or decline incoming calls, mute/unmute during a call, or hang up.
Speed Assist
Speed Assist now leverages the car's cameras to detect speed limit signs, improving the accuracy of speed limit data on local roads and highways in select countries. Detected speed limit signs will be displayed in the driving visualization. The vision-based speed assist feature now includes support for several additional countries, such as Australia, Sweden, Portugal, and Luxembourg.
Expanded Zoom Availability in Multiple Countries
Tesla has extended Zoom availability to more countries, including Germany, France, Italy, the Netherlands, Norway and others. If you have a Zoom meeting in your Calendar, tap the link to start or join your meeting automatically. Participant video and screen sharing are only visible while parked and will switch to audio-only if you drive. It is the driver's sole responsibility to consult and comply with all local regulations while using Zoom. To access Zoom, tap Application Launcher > Zoom.

It was a rainy April 1st when a news-searching author went on a delve into the depths of April Fools to find fact from falsehood. And while we found a lot of fantastic jokes, we also found some good ideas.
So, with a shoutout to MarcoRP on X, whose April Fool’s Joke gave us a good run for our money for a couple of minutes, we thought to ourselves - what would a Cybercab Charging Station / Cleaning Hub really look like?
Cybercab Wireless Charging Sites
Now, before continuing, we’d like to point out that the image up top is a joke from Marco - it isn’t an accurate or real site map submission from Tesla. However, it gave us the impetus to think critically about what is required for a Robotaxi fleet, based primarily on the Cybercab, to be able to service a city.
Requirements
Tesla will likely need to charge a small fleet of Cybercabs at a single time and in a single place. That means that the site needs to be large enough to cover a major metro area while also still being compact enough to not cost too much money to build out.
In addition, we need to factor in charge times. The Cybercab is likely to launch with a battery around 50 kWh, which will result in a range of approximately 300 miles. With that much range, the average Cybercab may not need to charge more than once or at all during daytime shifts, so instead, most of the vehicles will charge overnight.
MarcoRP
Math and Charge Times
The overnight charging means that most of these vehicles could be charged slowly. When we did some back-of-the-napkin math last year, we determined that Tesla’s wireless charger will likely peak around 17 kW (for comparison, Tesla’s Wall Connector at 32 amps charges at about 7 kW). If we scale Tesla’s wireless charger down slightly to 10 kW, accounting for some energy loss and the potential size of the site, that means a Cybercab will be able to charge in about 5 hours.
Tesla’s upcoming V4 Supercharger unit can currently handle 1.5MW per cabinet, but this slower-speed charging is A/C, not DC, which means there is a step-down loss of about 3-5%. Let’s make that a comfortable 10% for any other overages, but we can estimate around 1.35MW of power. That 1.3MW will easily handle charging up to 100 Cybercabs at once - all wirelessly, using Tesla’s unique beam-forming and beam-steering technology to keep efficiency high at every single stall.
Within about 5 hours, a whole fleet of 100 Cybercabs could be charged overnight when electricity rates are cheaper and still be out in time for the morning commute.
While this is all just hypothetical, it really does make sense that Tesla will be establishing these sites that won’t require much space or a ton of energy.
Tesla recently curtained off a large section of the parking garage at Giga Texas, as well as some of their chargers on the eastern end of the facility, leading us to believe they may just be testing this at scale internally.
There’s a lot to look forward to with Tesla’s V4 Supercharger deployment coming this year and with Robotaxi launching in just a couple of months.
Tesla released its Q1 2025 delivery and production numbers this morning, reporting 336,681 vehicles delivered and 362,615 produced—marking the company’s weakest quarter since 2022. Deliveries declined 13% year-over-year and fell well short of Wall Street estimates, which ranged from 360,000 to 370,000. Some analysts had forecast as many as 407,000 units.
Despite the shortfall, Tesla stock is actually up about 4% this morning, not only suggesting the market had already priced in weaker performance, but that this may be seen as the low point for the company. Tesla began delivering its refreshed Model Y in March, and production across all four Gigafactories was impacted by several weeks of downtime as Tesla retooled lines to accommodate the newer model. However, there’s no doubt that there is some brand impact from Elon Musk.
Comparing Numbers
Most of the deliveries—323,800 units—came from the Model 3 and Model Y lineup, while the “Other Models” category (including the Cybertruck, Model S, and Model X) accounted for 12,881 deliveries. That’s a 31% drop for Model 3/Y and a sharper 45% drop for the Other Models category compared to the previous quarter. However, comparing it to a more applicable Q1 2024, these numbers are only down about 13% for the Model 3/Y and down about 24% for the Model S/X and Cybertruck.
In terms of production, Tesla built 345,454 Model 3/Y vehicles and 17,161 from its “Other Models” line. The company attributed the production drop to the Model Y changeover but said the ramp is “going well.” This still leaves a large gap between production and delivery numbers, although they may not be as large as many had feared.

Cybertruck
One major weak point in Tesla’s numbers seems to be Cybertruck deliveries. While Tesla previously expected the Cybertruck to sell more than 250k units per year, we’re already seeing a decline in numbers. This is likely due to several factors, including the higher-than-expected price point of the truck, the unavailability of the RWD model, and the Cybertruck’s polarizing design, which may attract unwanted attention right now.
While the Cybertruck was ramping up production in 2024, making the lower numbers reasonable, the deliveries for Q1 2025 dropped drastically compared to the previous quarter. Cybertruck deliveries are estimated to be in the 5- 6k unit range for the quarter.
The good news to take away here is that the Single Motor variant of the Cybertruck appears to be nearing release. The price of the RWD version is expected to be about $60k USD before any incentives.
Q1 Earnings Call
Tesla announced their quarterly numbers this morning and posted on social media that they’ll live stream their Earnings Call on April 22nd.
This post was later edited to change “Q1 Earnings Call” to “Q1 Company Update.” It’s not clear whether there’s any significance in this change, but it could mean that Tesla has more to announce during the call.
The Company Update will occur on April 22nd at 2:30 PM PT / 5:30 PM ET. The standard Q&A session with executives and Musk is expected to follow the release of additional financial results for the quarter.
Tesla is set to launch its long-awaited Robotaxi service in June, and a cheaper, mass-market model is also planned for this year. With delivery numbers coming in soft and the refreshed Model Y just hitting the road, all eyes will be on forward-looking commentary during the update.
