Tesla to Start Using Audio and Vision in FSD V13.4

Whole Mars Catalog

With FSD V13.2.1 finally rolling out to HW4/AI4 vehicle owners this week, we’ve been super excited to see all the new features, including Park, Unpark, and Reverse in action for the first time.

However, that’s not everything - more is coming soon. We previously reported that Tesla is collecting audio input to build neural networks for audio, and now we’re learning that that capability will arrive in FSD V13.4.

Better Audio Handling

Ashok Elluswamy, Tesla’s VP of AI, mentioned that better handling of audio inputs is coming as part of FSD V13.4. That’ll be an interesting change, as the current handling of emergency vehicles on V13.2.1 is already pretty good.

However, we’re sure that being able to recognize emergency vehicles audibly will improve detection speed and reliability. Similarly to vision, FSD will start analyzing all the sounds it hears, and look for signs of emergency vehicles.

FSD will be able to make a reasonable determination on whether the sound of the siren is approaching or just echoing off of nearby terrain or buildings using the Doppler effect. It’s a simple mathematical principle where the frequency of a sound wave increases as the source moves towards the observer and decreases as it moves away. 

Interestingly, Tesla will be using the internal microphone for this task - as there are no external microphones on any Teslas… yet. This microphone is sufficient for one simple reason - sirens are made loud enough for humans to hear them inside a moving car.

Better Than a Human

Some users have wondered how the vehicle will be able to distinguish between sirens on the radio and in real life. While I’m sure we’re not the only ones to have ever been fooled by a siren on the radio, Teslas won’t be as easily fooled.

Tesla could actually take the audio going out to the radio and remove it from the sounds captured by the microphone, effectively removing sirens from the captured audio. In addition to being able to measure the intensity and direction of the sound, your vehicle should be able to accurately recognize emergency vehicles, even before a human can.

Opt-In Audio Sharing

Tesla is now allowing FSD users to opt-in to sharing audio data. The prompt for sharing audio data is on FSD V12.5.6.4, V13.2 and V13.2.1. It’s also expected to be in the upcoming Hardware 3 version of FSD 12.6.

However, it’s worth noting that Tesla’s release notes between V13.2 and V13.2.1 changed slightly for audio sharing. Tesla initially mentioned that the vehicle would capture 10-second audio clips when a siren is heard.

In FSD V13.2.1, Tesla updated the data sharing feature, letting users know that audio recordings are now said to be captured when the vehicle detects an emergency vehicle instead of detecting a siren. The audio clip is also not limited to 10 seconds anymore.

Opting into audio sharing will share microphone recordings alongside all the other data that Tesla regularly collects as part of its FSD training. Of course, if you're uncomfortable with that, you’ll be able to opt out of just the audio portion. Tesla’s privacy policy also discloses that they anonymize and sanitize the data during collection and processing.

While vision plays a much larger role, expect Tesla to deal with the capturing and analyzing of audio data in a very similar manner.

We’ve already seen improved handling for school buses on V13.2, so we’re excited to see what else Tesla does in the next few months. Perhaps handling school zones would be the next big item to tackle.

Tesla FSD in Europe: June Update

Not a Tesla App

The road to bringing FSD to Europe has been a long and complex one and filled with regulatory and bureaucratic hurdles. Elon Musk, as well as other members of Tesla’s AI team, have previously voiced their grievances with the regulatory approval process on X.

However, it appears that there is finally some progress in getting things moving with recent changes to upcoming autonomy regulations, but the process still seems slow.

Waiting on the Dutch

Elon commented on X recently, stating that Tesla is waiting for approval from Dutch authorities and then the EU to start rolling out FSD in Europe. Tesla is focusing on acquiring approvals from the Dutch transportation authority, which will provide them with the platform they need to gain broader acceptance in Europe. Outside of the Netherlands, Tesla is also conducting testing in Norway, which provides a couple of avenues for them to obtain national-level approval.

The frustration has been ongoing, with multiple committee meetings bringing up autonomy regulation but always pulling back at the last second before approving anything. The last meeting on Regulation 157, which governs Automated Lane Keeping Systems, concluded with authorities from the UK and Spain requesting additional time to analyze the data before reaching a conclusion.

Tesla, as well as Elon, have motioned several times for owners to reach out to their elected representatives to move the process forward, as it seems that Tesla’s own efforts are being stymied. 

This can seem odd, especially since Tesla has previously demoed FSD working exceptionally smoothly on European roads - and just did it again in Rome when they shared the video below on X.

DCAS Phase 3

While the approval process has been slow, Kees Roelandschap pointed out that there may be a different regulatory step that could allow FSD to gain a foothold in Europe.

According to Kees, the European Commission is now taking a new approach to approving ADAS systems under the new DCAS Phase 3 regulations. The Commission is now seeking data from systems currently operational in the United States that can perform System-Initiated Maneuvers and don’t require hands-on intervention for every request.

This is key because those are two of the core functionalities that make FSD so usable, and it also means that there may not be a need to wait years for proper regulations to be written from scratch. Now, the Commission will be looking at real-world data based on existing, deployed technology, which could speed up the process immensely.

What This Means

This new, data-driven regulatory approach could be the path for Tesla to reach its previous target of September for European FSD. While the cogs of bureaucracy are ever slow, sometimes all it takes is a little data to have them turn a bit faster in this case.

Alongside specific countries granting approval for limited field testing with employees, there is some light at the end of the tunnel for FSD in Europe, and hopes are that a release will occur by the end of 2025. With Europe now looking to North America for how FSD is performing, Tesla’s Robotaxi results could also play a role.

Tesla Launches 'TeslaVision' Contest With Big Prizes — See Last Year’s Winner [VIDEO]

Not a Tesla App

Tesla’s marketing has always been relatively unconventional, relying on word-of-mouth rather than traditional advertising. The passion of the owner’s community is always massive, but it is especially high now with the launch of the Robotaxi network just around the corner.

Tesla is now tapping into that spring of fan creativity and announced the TeslaVision video contest, with some seriously impressive prizes up for grabs.

Announcing the TeslaVision fan video showcase

Tesla owners & supporters have always been able to see our products & mission for what they truly are.

Your word of mouth has made Tesla what it is today.

The OGs will remember that in 2017, we held our first video contest. 8 years… pic.twitter.com/6pPpkqmqOH

The Contest

The core of the contest is simple. Create a video that shows how your Tesla gives you more in life. Tesla is looking for submissions that highlight themes of freedom, safety, fun, and convenience.

Prizes

The prizes definitely make this contest worth entering if you’re good with a camera and have some basic video editing abilities.

For North America, the prizes include a brand new Model Y AWD Long Range, alongside an all-expenses-paid trip to Austin for a tour of Giga Texas. The grand prize winner will also be able to custom order their Model Y, allowing them to select their preferred wheels and color.

The two runners-up won’t get a Model Y, but they’ll also enjoy an all-expenses-paid trip to Giga Texas for a tour of the factory.

The travel and tour include lodging in Austin for 2 nights, as well as economy-class round-trip tickets from anywhere in North America. Tesla will also provide a vehicle for use during the trip.

Hopefully, these winners will also have the opportunity to experience the Robotaxi network while they’re in Austin, as it’s expected to be opened to the public later this month.

Project Loveday

For long-time followers of Tesla, this contest may feel familiar. The contest is a direct throwback to the 2017 Project Loveday contest, which was inspired by a letter to Tesla from a 10-year-old aspiring marketer. That contest was won by MKBHD, with his submission below:
