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.

The ability to adjust wipers using the steering wheel has been discovered as an undocumented feature in the 2023.12.1 release notes. You

You can now adjust the windshield wiper speed by using the scroll wheel on the steering wheel. First, press the button at the end of the left stalk to activate the windshield wipers and have the controls appear on the screen.

You can then tilt the left scroll wheel left/right to cycle through the various speeds of the windshield wipers.

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.

Navigate to Controls > Display > Text Size to adjust your preference. With these exciting new features and improvements, Tesla's 2023.12.1 software update enhances the overall driving experience for its users.

This comprehensive overview of Tesla's 2023.12.1 software update showcases the automaker's commitment to continuously improving its vehicles' features and driving experience for its users. With each update, Tesla further cements its position as a leader in the electric vehicle market.

Musk Confirms Robotaxi on Track for June, More Cities Coming, Customer-owned Cars in 2026

Tesla signaled its intention to launch its first Robotaxi network in Austin, Texas, with company-owned and operated vehicles, back in January. This network will be Tesla’s first foray into truly autonomous vehicles - ones that aren’t being directly supervised by a driver. Later in February, Tesla’s executive team confirmed that the plans were on track for the launch of the Austin network both on X and during several interviews that they participated in.

At the end of February, we also found out that Tesla has applied for a Supervised Robotaxi license in California, where the network will also launch, but with safety drivers in place.

This is an ambitious plan, but FSD has really come a long way in the past year. FSD V12 was a massive step forward from V11, and V13 has made the experience smoother and safer than ever before. FSD V14 is expected to be another big step up with auto-regressive transformers and audio input.

Still on Track

Now, Elon has tripled down on the fact that Tesla will be launching their first autonomous robotaxi network in Austin - just two months away at this point. It seems that Tesla is fully set to launch their first fully unsupervised self-driving vehicles that will carry paying passengers in June.

Additional Cities

The best part is that Elon also confirmed that they’re targeting robotaxi networks launching in many cities within the United States by the end of this year. However, remember that this will be a Tesla-run network at first - Tesla owners won’t be able to add their vehicles to the Robotaxi fleet right away.

Adding Customer Vehicles

It will take some time before Tesla meets their strict internal safety requirements before it lets customers add their own vehicles to the network. Tesla’s executive team mentioned that they intend to let owners add their own vehicles to the fleet sometime in 2026. This happens to be the same time frame that Tesla plans to launch the Robotaxi across the United States, Mexico, and Canada — something that could only be done with customer-owned cars.

That final step will be bold—and it may come with complications, especially given that autonomous vehicle approval spans municipal, state or provincial, and even federal levels. There are plenty of regulatory hurdles ahead, but this is undoubtedly shaping up to be one of the most exciting times for Tesla.

Launch Event

With the Robotaxi network launching and Unsupervised FSD just around the corner, there’s a lot to get excited about. Tesla is expected to host a launch event at Gigafactory Texas in Austin to mark the debut of its first Robotaxi network. The company previously hinted that referral code users could receive invites—offering a rare chance to score an early ride in a Robotaxi outside the Hollywood studio lot.

Tesla Mule Model 3 Spotted With Front Bumper Camera

Tesla’s engineering mule vehicles—used to test autonomy for future platforms—have resurfaced after an extended absence. The last time we saw them was back in July, when Tesla was gearing up for its initial We, Robot event. Since then, sightings have been scarce.

These vehicles typically signal that Tesla is testing new camera placements or validating FSD ground-truth data. This time, however, they appear to be outfitted exclusively with the updated camera hardware seen on the Cybercab.

New Sightings

The mules have now been spotted in Boston, Massachusetts, and Concord, New Hampshire—their first known appearances this far east. This suggests Tesla is actively collecting data to evaluate and optimize FSD performance in new regions. Thanks to Reddit user Ready_Medium_6693 for catching the one in Concord.

Elon Musk recently mentioned that Tesla plans to expand Robotaxi networks beyond the initial Texas and California launches. So while these sightings aren’t entirely unexpected, the speed of their arrival is. It suggests Tesla is confident in its ability to train FSD for local traffic rules and driving behaviors to the point it no longer needs a driver.

Bumper Cameras

The vehicle that’s been spotted in Boston is the usual Tesla engineering Model 3… except with one unique twist. It includes a front bumper camera. Shout out to @Dylan02939106 for catching the bumper camera in these photos.

We previously released an opinion piece regarding whether the front bumper camera would be required for Unsupervised FSD. In our eyes, Tesla will require a bumper camera for Unsupervised FSD - if only to improve direct visibility in the bumper area of the vehicle. This is key for low-speed maneuvering in crowded areas like parking lots and garages, as well as for key features like Actually Smart Summon. 

It isn’t surprising that Tesla is continuing to evaluate vehicles with a bumper camera - the Cybertruck, Cybercab, and Refreshed Model Y all have them now - and the rest of the lineup, including the flagship Model S and X, as well as the refreshed Model 3 - were supposed to eventually receive them as well.

With the Model S and Model X set for refreshes this year—and the front bumper camera on this Model 3 looking well-integrated rather than a temporary setup—it seems likely that front bumper cameras will soon become standard across Tesla’s entire lineup.

In fact, Tesla’s newest iteration of the FSD computer has a slot for the Bumper Camera on all AI4/HW4 vehicles, so a future retrofit could even be possible.

These are some pretty exciting times - we may see Robotaxi networks actually deploy in time for Tesla’s lofty goal of “sometime in 2026” for cities throughout North America. Once many American cities begin to accept their deployment, it will be easier to seek homologation in Mexico and Canada, enabling deployment throughout the continent.
