How to increase your Tesla Safety Score

If you've opted-in to Tesla's assessment of your driving behavior, then you're likely trying to get access to Tesla's FSD Beta. In order to do that you'll need as high of a score as possible. The higher the score, the sooner you'll be granted access to the FSD Beta.

Tesla's very transparent about how your Safety Score is calculated. We'll share some information for each category Tesla is grading and also share some tips on how you can improve your score.

There are five categories that Tesla is actively measuring drivers against. It's important to be familiar with them, as not everything counts toward your Safety Score. Your performance in each category is measured to the median of Tesla's fleet.

Forward Collision Warnings (FCWs)

First, we have Forward Collision Warnings. This is the car giving you a warning that you're going at a high rate of speed relative to the distance you have to the object directly in front of you.

Tesla bases this off the ‘medium' setting in FCW. I'd recommend going to Autopilot > Forward Collision Warning and setting your personal alert level to ‘Early'. This way you'll be made aware of the potential collision before Tesla dings you for it.

There's not much to this one, except to keep your distance and slow down before you get too close to the vehicle or object in front of you.

Hard Braking

This is a tough one and the one I've struggled with the most. You'll want to very gradually slow down when coming to a stop. Quite a bit more than you'd likely think you need to. One harsh stop and you'll be dinged.

Tesla identifies hard braking as a backward acceleration greater than a g-force of 0.3. I personally love to take full advantage of the car's regenerative braking. So if I have a shorter distance to stop, I'll let my foot off the accelerator a little quicker to receive a higher level of regen, but doing so exceeds the 0.3g Tesla specifies and will set you back. Brake early and gradually to avoid any negative scores due to hard braking.

Aggressive Turning

Similar to harsh braking, Tesla is looking at the g-forces here when determining aggressive turning. If the lateral g-force exceeds 0.4g, then your score may be affected.

You'll want to make sure you're not going faster around turns. The tighter the turn, the slower you'll want to go.

Unsafe Following

This is the distance between you and the vehicle in front of you. It's similar to Forward Collision Warnings in that you'll want to make sure you leave enough room to stop between you and the vehicle in front of you, but Unsafe Following is only calculated when you're traveling above 50 MPH. An easy way to avoid penalties here is to use Autopilot with a follow distance greater than 3.

Forced Autopilot Disengagement

This is the act of using Autopilot and having it become disengaged because you didn't heed the warnings of applying pressure to the steering wheel. Not applying enough resistance on the steering wheel will not affect you here, neither will the car beeping. It is only considered a forced disengagement if the vehicle asks you to apply resistance three times and then disables Autopilot for the remainder of the trip.

Keep in mind that Autopilot will also be disabled if you exceed 90 MPH for vehicles with radar or 80 MPH for vision-only vehicles, while on Autopilot.

Tips

Although, I don't personally encourage this tip, as we want everyone to be fair, there is currently a way of having your drive not count toward your Safety Score. If you do a soft reset before you park your car, the drive will not be registered and will not count toward your overall Safety Score. This will likely be fixed in a future update.

Each driving category is weighted differently. So having Autopilot disabled isn't the same as having an instance of harsh braking.

Here is how much each category negatively affects your score, from the worst offender to the least.

• Forced Autopilot Disengagement
• Hard Braking
• Aggressive Turning
• Unsafe Following
• Forward Collision Warnings

Autopilot

While you're driving on Autopilot your score is not negatively affected, even if the car follows too closely or gets a FCW. Tesla simply ignores any bad driving if Autopilot is engaged. You may want to consider using Autopilot in more situations when you feel it's safe.

If you're using Autopilot on city streets, remember to disengage it with plenty of time before your turn so that you can slow down gradually before taking the turn.

Acceleration

Although acceleration or speeding do not negatively affect your score, it could result in sudden braking or Forward Collision Warnings, which would impact your Safety Score.

Other Metrics

Tesla collects a lot of information on how we use our cars. They use this information to improve features, roll out new ones and make their cars safer.

Although Tesla is showing us these five metrics that they're using to assess your Safety Score, Tesla could potentially use more information than just your Safety Score when choosing the next batch of beta testers. They're probably not looking for individuals who are driving 200 miles a day, or those that are rarely driving. You'll probably want to be in a sweet spot where you drive most days, but aren't taking long trips.

Tesla may also use information that is out of your control such as your geographical region or how long you've had your car.

Use Other Cars

If you're already driving your Tesla most days, don't take the chance of ruining a good score. If you're in a rush or already drove your Tesla today, consider taking a spouse's car when possible.

Save your Tesla for driving on familiar roads, roads where you know when a sharp turn may be coming up or where stop signs are. Use your Tesla when you have the extra time to take it slow and really focus on the road.

Lastly, be safe. We all want a high Safety Score, but at the end of the day we all need to come home in one piece.

If you're looking to figure out how many miles you'll need to drive to reach a specific score, such as 99, I strongly recommend using our Safety Score Calculator that will give you exactly that answer. After adding your data, you can choose a target score and know exactly how much more you'll need to drive to achieve your goal.

Tesla LFP Batteries Can Now Be Warmed up While Supercharging Using Innovative Feature

Not a Tesla App

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 Included FSD V12.6.1 and V13.2.4 in the Same Update: What Caused This and What It Means

Not a Tesla App

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.

While this update focuses on bug fixes, Tesla’s already working on bigger features for FSD V13.3, which we have already confirmed to include improvements to highway following and speed control.

FSD V12.6.1

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.

Thanks to Greentheonly for helping us understand what happened with this release and for the insight into Tesla’s processes.
