Tesla is finally expanding the FSD Beta to more testers who have been patiently waiting and maintaining high Safety Scores.
Elon Musk announced the expansion on Twitter and said Tesla would expand the beta to 160,000 testers in the United States and Canada, up from 100,000.
He has said the program could only improve with more real-world driving data input. The real-world experience could have been drivers achieving nearly perfect Safety Scores.
Lower Safety Score
Tesla has now lowered the Safety Score required to get into the FSD Beta program. Anyone in the U.S. or Canada or who has driven more than 100 miles with a Safety Score of 80 is now eligible to receive the beta.
Early this morning owners began waking up to a surprise update from Tesla. Tesla started sending out the latest FSD Beta, 10.69.2.2 (update 2022.20.17) to new testers overnight.
Only for those on 2022.20 or earlier?
It appears that those receiving the beta have been on a version of 2022.20 or earlier. Owners on update 2022.24 or 2022.28 haven't been offered the beta yet.
It's possible Tesla wants to prevent rolling owners backward in terms of updates, causing some features to be removed. Potentially features that the owners may have just started getting used to such as blind spot camera placement, alternate routes, or other features included in update 2022.24 or 2022.28.
Elon has already commented on the next version of FSD Beta, revealing that it will be beta 10.69.3 and it's expected to be released shortly after AI Day Part II. This version could be based on update 2022.24 or 2022.28 and include testers currently on those updates.
For those unfamiliar, just because someone purchases FSD doesn’t mean they have access to the FSD Beta. No, the driver is graded by Tesla and given a score. That score has to be above a certain point to be enrolled in the FSD Beta. Tesla’s CEO has said that more than 100 million FSD miles should be logged by the end of 2022. In July, that number stood at 35 million miles. Of course, to triple that number, more testers are needed.
In August, Tesla’s CEO was confident FSD had a breakthrough and told shareholders the next update would be so great that he had to break the order of numbers, “… we’ve made some pretty significant architectural improvements. So, it is really more than 10.12 to 10.13 release. It might, I don’t want to speak too soon, but it might qualify for 10.69. It has to earn that, obviously!”
While the price of FSD continues to go up, Musk says this about making the roads safer, “We’re solving a very important part of AI and one that can ultimately save millions of lives. And prevent 10 of millions of serious injuries by driving just an order of magnitude safer than people.”
Autonomous vehicles have been a goal for years. Musk publicly discussed it in 2017 and believed the feat could be done in two years. However, a few months ago, he admitted it was a much more significant challenge than he predicted. “The sheer amount of work required to do this boggles the mind,” he told the Tesla Owners Club of Silicon Valley. “I’ve seen a lot of tough technology problems, and solving real-world AI such that a car can drive itself is one of the hardest problems I’ve ever seen. It is way harder than I originally thought, by far.”
Were you newly invited to FSD Beta if you had a 80+ score?
Since 10.69 was released on August 20, updates have included several improvements to FSD. The most recent update can be found here. Now with 60% more users, there will be more updates to address what Teslas are experiencing. Plus, there is already FSD Beta 10.69.3 expected just after AI Day on September 30.

Tesla’s been on a roll with Supercharger improvements lately, from the 325kW charging update for the Cybertruck, to 500kW with V4 Superchargers coming next year. While those improvements have been limited to the Cybertruck, Tesla didn’t put all their focus on their new flagship vehicle, but looked at their more affordable vehicles as well.
LFP Battery Heating
Tesla’s Superchargers can now heat LFP Batteries - those that are in the Model 3 and Model Y Rear Wheel Drive variants. This applies to Long Range and Standard Range models, which saw a limited run. This is another update included as part of the 2024 Tesla Holiday Update - which really arrived with a lot of unannounced new features and capabilities.
The change is pretty interesting - Superchargers of the V3 and V4 variety can now pre-heat batteries for Model 3 and Model Y vehicles equipped with LFP battery packs. That means those vehicles are able to get back on the road faster when it's extremely cold. Of course, Tesla still advises you to precondition before you arrive, saving drivers time and money.
Max de Zegher, Tesla’s Director of Charging, also commented on the new feature. Essentially, Tesla is inducing an AC (alternating) ripple current through the battery to warm it up. Keep in mind that Superchargers are DC charging. That means it is possible to get a cold-soaked LFP vehicle on the road 4x faster than before, assuming that it didn’t precondition at all and that it is in the worst-case scenario (below 0ºF).
In essence, Tesla is using some engineering magic to turn the circuits inside the LFP battery into an electric heater - and powering that heater through the Supercharger. An AC ripple current is a small oscillation in the DC charging current that generates heat through electrical resistance, warming up the battery. Those ripples are a byproduct of converting AC to DC and back - so Tesla is using the onboard charger to induce those ripples to warm up the battery. Definitely an innovative technique that’s really only possible with the versatility of the NACS connector.
We’re hoping Tesla can implement this across their full lineup of vehicles, but we’ll have to wait and see how it is trialed across LFP vehicles first and if it is even possible on vehicles with 2170 or 4680 battery packs.
Tesla launched two FSD updates simultaneously on Saturday night, and what’s most interesting is that they arrived on the same software version. We’ll dig into that a little later, but for now, there’s good news for everyone. For Hardware 3 owners, FSD V12.6.1 is launching to all vehicles, including the Model 3 and Model Y. For AI4 owners, FSD V13.2.4 is launching, starting with the Cybertruck.
FSD V13.2.4
A new V13 build is now rolling out to the Cybertruck and is expected to arrive for the rest of the AI4 fleet soon. However, this build seems to be focused on bug fixes. There are no changes to the release notes for the Cybertruck with this release, and it’s unlikely to feature any changes when it arrives on other vehicles.
FSD V12.6.1 builds upon V12.6, which is the latest FSD version for HW3 vehicles. While FSD V12.6 was only released for the redesigned Model S and Model X with HW3, FSD V12.6.1 is adding support for the Model 3 and Model Y.
While this is only a bug-fix release for users coming from FSD V12.6, it includes massive improvements for anyone coming from an older FSD version. Two of the biggest changes are the new end-to-end highway stack that now utilizes FSD V12 for highway driving and a redesigned controller that allows FSD to drive “V13” smooth.
It also adds speed profiles, earlier lane changes, and more. You can read our in-depth look at all the changes in FSD V12.6.
Same Update, Multiple FSD Builds
What’s interesting about this software version is that it “includes" two FSD updates, V12.6.1 for HW3 and V13.2.4 for HW4 vehicles. While this is interesting, it’s less special when you understand what’s happening under the hood.
The vehicle’s firmware and Autopilot firmware are actually completely separate. While a vehicle downloading a firmware update may look like a singular process, it’s actually performing several functions during this period. First, it downloads the vehicle’s firmware. Upon unpacking the update, it’s instructed which Autopilot/FSD firmware should be downloaded.
While the FSD firmware is separate, the vehicle can’t download any FSD update. The FSD version is hard-coded in the vehicle’s firmware that was just downloaded. This helps Tesla keep the infotainment and Autopilot firmware tightly coupled, leading to fewer issues.
What we’re seeing here is that HW3 vehicles are being told to download one FSD version, while HW4 vehicles are being told to download a different version.
While this is the first time Tesla has had two FSD versions tied to the same vehicle software version, the process hasn’t actually changed, and what we’re seeing won’t lead to faster FSD updates or the ability to download FSD separately. What we’re seeing is the direct result of the divergence of HW3 and HW4.
While HW3/4 remained basically on the same FSD version until recently, it is now necessary to deploy different versions for the two platforms. We expect this to be the norm going forward, where HW3 will be on a much different version of FSD than HW4. While each update may not include two different FSD versions going forward, we may see it occasionally, depending on which features Autopilot is dependent on.
