Apple Music may be available in Tesla’s new holiday update, but don’t expect the lossless audio quality that Apple Music subscribers enjoy… at least not yet.
Tesla owner and software developer Dan Burkland recently performed some tests on the audio quality that Tesla’s in-car streaming services TIDAL, Spotify, and now Apple Music stream at in the vehicle.
Burkland tested TIDAL previously on a different Tesla software version, but with Tesla’s ever-changing software and the rollout of the holiday update, he chose to run the tests again.
Setup and Songs Used to Test
He connected his Model Y to his home's WiFi network and used a DHCP reservation, which allowed him to have the vehicle use a specific IP address. He then installed ntopng on his OPNsense firewall to monitor traffic statistics for the vehicle. After zeroing out the host stats for the Model Y, he tested a total of nine songs, including “Purple Rain” by Prince, “Foreplay” by Boston, and “Kashmir” by Led Zeppelin.
Results
The results of Burkland’s tests concluded that TIDAL still offers the best listening experience. The average bitrate for TIDAL was ~1165 kbps. This isn’t entirely too shocking, as TIDAL has always championed the highest-quality audio streaming experience.
Surprisingly, Spotify’s audio quality came in ahead of Apple Music to nab second place. Burkland’s tests showed Spotify streaming at an average bitrate of ~157 kbps, while Apple Music came in at a subpar ~118 kbps.
Burkland added that he believes Apple Music is limiting bitrate for the in-car app, but a future update to Tesla’s software will hopefully resolve this. If Tesla can enable lossless streaming for Apple Music, it’ll give TIDAL a run for its money in high-fidelity streaming via the in-car app.
Check out some of Dan’s test results below, or for a complete list view his Reddit thread.
During their tests, they observed the same pattern across all songs, citing that a bunch of data rolled in at the beginning of the tests and then slowly trickled through. The low data rate for Apple Music appears to align with the company’s HE-AAC codec at 64 kbps.
“It appears to buffer most or even all of the song, then pause between tracks to do it again,” writes u/OverlyOptimisticNerd. “On average, I saw ~2MB per track, with ~1.7MB during the initial burst and ~0.3MB throughout the track. This is consistent with the HE-AAC standard, as most of these songs were a little over 3 minutes in length.”
While Apple Music may come in at the lowest average bitrate of all three services tested, it's important to note that it doesn't necessarily mean it has the lowest quality. Audio quality comes down to a variety of factors, some of which are, the bitrate, whether it's a variable rate, and the efficiency of the audio codec used.
Apple Music's HE-ACC codec is optimized for low-bandwidth applications meaning that it can outperform an ACC-encoded file in lower-bandwidth situations. In the real-world Apple Music in your Tesla should sound very similar to streaming music from Spotify, but not as good as TIDAL's offerings.

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’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.
