FSD 12.5.2.1 is what's going out at the moment. Big wave, I got it this morning as well.

ahorseofborscht 2024-09-23 13:09

I wonder when 12.5 is gonna hop over to the "normie" update releases, maybe with the holiday update?

TeslaM1 2024-09-23 13:14

2020 MYP Atom. Just got the update

refpuz 2024-09-23 13:19

2019 M3, still no update as of this morning :(

CryptographerDear250 2024-09-23 13:20

12.5 for thee, not for me. 🤷

coolham123 2024-09-23 13:21

I have watched a ton of FSD content over the years and still don’t understand the software branch system they use, and why they use it. I understand the concepts of dev testing, quality, then wide release, but to me this system seems very “messy”? Maybe someone who knows more can explain why on the latest production version you would still get FSD 12.3.6?

[deleted] 2024-09-23 13:23

Should would be nice. I’ve been sitting on 2024.6.7 for months. (23 MYP)

technolgy 2024-09-23 13:24

Crazy. This is a huge regression and they know it. Gathering more data and endangering people in the process.

[deleted] 2024-09-23 13:29

Teslafi lists 2024.27.10 going out to Canada too. I think that's the first 12.5 in Canada

kenypowa 2024-09-23 13:30

Got it on my 2018 Model3. Finally.

cmdr-William-Riker 2024-09-23 13:35

Any good news? Any improvement over 12.3.6?

Tcloud 2024-09-23 13:35

“The largest wave went out on Thursday and Friday to more than 400 Tesla owners per day. The rollout has again slowed down since then with 50-100 installations per day on average.” They’re releasing slowly to the public for now., so I wouldn’t expect an update to my 2019 M3 for the near term.

Lispro4units 2024-09-23 13:35

The speed control on 12.5.2.1 (HW4)is horrible. It always goes 5-10mph slower than the speed limit when it’s auto max

mensrea 2024-09-23 13:36

Absolutely false in every way. Do you have it? What are you talking about?

[deleted] 2024-09-23 13:37

You have to fit the criteria they are looking for in the dev branch. Each update is supposed to fix "something" and they take people based on how many times that something triggered.

RyanBorck 2024-09-23 13:37

Received mine Friday. 2018 M3LRRWD.

RyanBorck 2024-09-23 13:38

No nag is cool.

rideincircles 2024-09-23 13:38

Mine is taking forever to download. It was at 40% the other day and 51% now.

RyanBorck 2024-09-23 13:40

You’re only realizing this has been the case from the very beginning?

DoublePotential6925 2024-09-23 13:40

Have not received: 2018 M3 LR

kenypowa 2024-09-23 13:40

Noticable improvement.

ChemistStrange6801 2024-09-23 13:41

Ya but 12.5.4 went out today with ASS and Vision with Sunglasses I want that not [12.5.2.1](http://12.5.2.1)

[deleted] 2024-09-23 13:41

It sounds like they have a lot of hardware versions beyond the HW3 HW4 stuff. background: I'm in software development (not Tesla) and there are constantly multiple branches in development and maintenance. Branches are split off for new hardware. Then that branch gets merged back into the main after release. Real branches are splitting and combining all the time. The version number stuff is just labels that are planned before the development even begins.

8qubit 2024-09-23 13:42

If I install this, will I get ass?

hydrated_purple 2024-09-23 13:42

2021 Model 3 - update is downloading now!

ChemistStrange6801 2024-09-23 13:43

I have had [12.5.1.3](http://12.5.1.3) in Canada for about 10 days now. It was the update I got after picking up my 2024 MY LR AWD in Vancouver last Saturday.

Possible_Version2680 2024-09-23 13:43

I. WANT. ASS GIVE IT TO ME

ChemistStrange6801 2024-09-23 13:44

I have [12.5.1.3](http://12.5.1.3) and its amazing over 12.3.6 way less interventions.

reefine 2024-09-23 13:45

I have it and agree it is a huge regression. It's extremely jittery for me following a car in front. Lots of micro adjustments. All around. Hesitancy almost seems more prevalent in this version, sort of "delayed" seemingly. Some lines it takes through bike lanes now. Seems like it takes a lot of lazy lines compared to previous. A lot more hesitancy with cut-in detection. During rush hour it seems like it was willing to have everyone get in front even making turns on right through an intersection. My car slowed down to let them through for no reason. Getting on the freeway it basically had zero awareness of the car I almost merged in to. It should have allowed space as it was a short merge but very straightforward. Previous version has seemed fine on that. Of course I don't get the nag free version for my car so I can't really say there's an improvement there ={ Not sure what's going on and why some of us are seeing worse performance. Someone theorized it's the older S/X with HW3.. 2016 S with HW3

Earthsiege 2024-09-23 13:51

Yep, I was surprised when I woke up to the [12.5.2.1](http://12.5.2.1) update notification. I thought for sure I wasn't going to get it this round, as I came from 12.3.6 on 2024.26.7.

[deleted] 2024-09-23 13:52

My wife and I both have 2021 m3. She gets updates all the time. I get them rarely. A little off topic, but why is this? It irks me that she has YouTube music and I don’t. (She has standard and I have LR fsd.) Update: the morning after the hurricane (south eastern USA) I awoke to the power being out and a notification that an update was ready for my car. Alas! YouTube music is mine!

ItIsMeTheGuy 2024-09-23 13:52

Oh wow! Thanks for the news! I didn’t catch this! Here’s the link for [12.5.4](https://www.notateslaapp.com/software-updates/version/2024.27.25/release-notes) with A.S.S, looks like it is in fact rolling out to a few already

CryptographerDear250 2024-09-23 13:53

lol if you find out let me know. being in software myself I can only guess they somewhat randomize their deployment rings, or groups of people they deploy to in progressive order, but having said that doubt it’s actually random. if she’s not on FSD and you are, those are totally separate branches of development which are occurring in parallel and moving at different paces.

oV1SEo 2024-09-23 13:53

Rocking my 2020 MYLR, I’ve never wanted A.S.S so bad.

Uphan2340 2024-09-23 13:53

Weird to have same car, same model S LR+, same year 2020, both with paid FSD but one with 2024.32.3 the other with 2024.27.10. Does not make sense.

[deleted] 2024-09-23 13:56

Mine tried to drive through a railroad crossing gate this morning. It camps in the left lane and misses right turns. It really is a mess.

WizrdOfSpeedAndTime 2024-09-23 13:56

It definitely improved the lane changing for me. Not sure on lane selection, it is mostly better I think. Auto speed is still a mixed bag. It seems to pick what a human would pick if they had no knowledge of the speed limit. Which means it falls for speed traps just like a human would. There is an overpass with an entrance to the freeway that has very short 25mph section that is insanely stupid and no one does it. Auto speed does it like the other humans. There is one three way stop that it doesn’t acknowledge at all. It has been under construction and change for a while. All other stops are fine.

RyanBorck 2024-09-23 14:02

AWD or RWD?

DoublePotential6925 2024-09-23 14:03

RWD

notasausage 2024-09-23 14:03

Ladies love Smart Summon.

RyanBorck 2024-09-23 14:03

FSD subscription or purchase?

DoublePotential6925 2024-09-23 14:04

Subscription

RyanBorck 2024-09-23 14:04

That’s likely it.

DoublePotential6925 2024-09-23 14:05

Well…it’s BS. 😂

MisterTwo 2024-09-23 14:07

I agree, I got this update last week (hw3) and miss 12.3.

nyrol 2024-09-23 14:09

Don’t worry, there are major issues with speed. Since updating to 12.5, mine seems to pulse the speed constantly. It isn’t enough to make the display change in mph, but it feels like it’s minimally feathering the pedal constantly. And now it seems to slam on the brakes for crosswalks when no one is there. I was driving this weekend and it would be driving about 5 mph above the speed limit, and then near each crosswalk on the road, it would slam the brakes to get to the speed limit. 12.3 never did this for me. But hey, turns are smoother now.

VonGeisler 2024-09-23 14:13

I’m still on my free 30 days and only on 12.3.6

szzzn 2024-09-23 14:15

Can’t wait to get the attention monitoring with sunglasses and ASS. But what’s this upcoming thing about myQ home integration? Isn’t that already a thing? Albeit awfully implemented bc it hardly ever works, hopefully it’s a fix for it.

[deleted] 2024-09-23 14:17

I just updated this morning. Can't try it until later on today or tomorrow. Hopefully it won't be a regression for me as some have mentioned.

ForevaWander 2024-09-23 14:17

It's been like this through a few past updates. I was hopeful it was resolved in this release. Its very annoying and doesn't happen when downgrading from FSD. Different software stacks perhaps but annoying AF.

Ray2K14 2024-09-23 14:19

Try tapping the accelerator pedal to get it up to speed. It's pretty good at respecting the override

[deleted] 2024-09-23 14:20

I don't see it showing up on Teslafi yet though.

pogopipsqueak 2024-09-23 14:28

i JUST experienced this over the weekend and found it frustrating to no end. after all these years of working one way now i just have to deal with the fact that the car is going to go ~5 mph slower than max when i’m alone on a road in broad daylight? not to mention the seriously jerky lane transition when exiting a highway. it used to be pretty fluid but now it’s like a violent lane change, all sudden and too quick to be comfortable. weird

wsxedcrf 2024-09-23 14:29

I got it too this morning, 2019 m3 HW3.

pogopipsqueak 2024-09-23 14:30

yes i found that too but im not trying to get it manually or via encouragement to adhere to the max speed i’ve set…im trying to get it to do so on its own the way it used to

wsxedcrf 2024-09-23 14:31

Well, at least I know I have something to look forward to in 2-3 weeks.

Upbeat-Ad-851 2024-09-23 14:37

It is literally hands free, I got mine last week and it isn’t awesome. 2019 model 3 LR dual motor. Criss crossed New Jersey mostly highway, no intervention needed. It takes ramps and exits much better than 12.3.6, but would love to see it do a little slower just a little slower, but I guess it’s based on human drivers, maybe I am a slow ramp off and exit kind of a guy. LOVE IT though

The_Don_Papi 2024-09-23 14:39

And on some videos it’s going 10-20 mph over the speed limit. Tesla needs to have Auto follow the speed limit when it sees a posted sign and allow owners to turn off Auto for places where signs aren’t posted.

[deleted] 2024-09-23 14:45

Oh wow that's awesome. I didn't see any on Teslafi but it doesn't cover everyone obviously How do you like it?

ChemistStrange6801 2024-09-23 14:47

Contrary to many people I love it have had many drives where i didn't touch anything just sat there. Compared to my 2020 MY with 12.3.6 its night and day to me.

[deleted] 2024-09-23 14:48

Very good to hear. I have a Y with 12.3.6. so I'm looking forward to this one.

soapinmouth 2024-09-23 14:50

12.5 was a major jump at first but the last couple point releases were a the downgrade. Made mistakes it never made on 12.4 Hope this .1 release is better.

TheGoodOldCoder 2024-09-23 14:53

In addition to what the other guy said, it could theoretically be something very simple, like your car isn't getting as good of a WiFi connection as her car. Like you park it slightly farther away, or something like that.

KforKaspur 2024-09-23 14:56

My HW3 2022 Model 3 LR just got it 2 days ago

TheGoodOldCoder 2024-09-23 14:58

I've been experiencing that for the last few updates on my HW3. I'm not sure about what's in each update, but I just got one where it asks you to toggle an option for it to drive at a natural speed. I got a little excited. I thought, if I keep this option off, maybe it will actually drive at the speed that I tell it to drive. Does it? Nope. It still drives 5-10mph slower. What if I turn that option on? Nope, it still drives 5-10mph slower, only now it doesn't let you manually set the speed.

technolgy 2024-09-23 14:59

I’ve had FSD since 2021. I’m talking about 12.5.2.1. It’s the biggest regression from a prior release, ever IMHO.

TheGoodOldCoder 2024-09-23 15:03

> It's pretty good at respecting the override To me, that is evidence that it is incompetently implemented. It obviously doesn't have a compelling reason to go slower. It just goes slower than requested for no reason. > Try tapping the accelerator pedal to get it up to speed. Even this doesn't work perfectly. If the speed limit is 50, the car will go around 45 or slower, and if you tap the accelerator, it will go up to somewhere like 48-49. If I tap the accelerator again, even to go above 50, sometimes it will go 50, but often it will slow down to like 49 again. If I wanted to go 49, I would have set the speed to 49.

BusOk4421 2024-09-23 15:10

I set it to no offset - follow speed limit. It's pretty reliable for me at holding speed. What is interesting is that you realize that if everyone followed the speed limit exactly (or 5-10% slower) safety would absolutely increase. We have some streets that are 25mph that regularly see 45mph+ (these are roads with TWO lanes in each direction and a median so 25 feels glacial. There are some bends with crosswalks (one near a liquor store) which ARE a bit risky at 45mph. 25mph is a totally different ballgame. Once I don't have to pay attention out the front I think they could just do speed limit, or even 5% below speed limit. MUCH longer reaction times for problems, and you are carrying less energy (by a lot it feels like) into any problems. You also realize how crazy human drivers are - lane changes with no signal, speeding, red light running, stop light running. My only complaint is the stop sign behavior - it's a bit unnatural and causes confusion for others. Some places have the stop line and stop sign offset, and sometimes I get a double stop - even worse for others. And sometimes the stop line is ridiculously far back, so I get a double stop closer to intersection so car can see. I realize it's some kind of NTHSA thing and so again, not a Tesla thing, but you realize something following the rules exactly reveals some weaknesses in the current setup.

DevinOlsen 2024-09-23 15:17

I have no idea if this could be why - but I regularly was getting the latest updates in one of the earlier waves, until I missed an update one time. I was away for work and my car was parked at the airport, while it was there an update came out and I couldn’t install it for a couple of weeks. When I got home the update was gone; and a couple weeks after that I got it with another “wave” of people who got the update. It seems like I’m now in that group of people when it comes to receiving updates. Almost like I lost my place in line. Absolutely no idea at all if this is how it works, just my thoughts.

LurkerWithAnAccount 2024-09-23 15:18

2017 S and 12.5.1.2 is garbage, especially in this regard. Feels exactly as you describe, pulsing throttling like a jittery cat. On older cars, I would stay on 12.3.6 until it’s clear that some newer build of 12.5.x has sorted this and horrendous auto speed control, quirky steering, stopping at stale green lights, and just overall noticeably worse performance on old HW3 cars.

Ice_Burn 2024-09-23 15:38

It’s there and has been for a couple hours. Not many installs yet

Buggabones1 2024-09-23 15:46

You got your answer inside your question. “She has standard, I have FSD.” Standard updates and FSD update are on two different things. Non FSD users get small updates constantly. It’s not a big deal if there’s a bug in the new game they released. They can still push it wide and fix it later. They can’t push a wide release if FSD is running red lights and just fix it later. FSD updates need to be tested and checked multiple times over before they can safely go wide, and even then it’s a slow release incase unknown bugs are found. What happens is standard users will be much farther ahead and FSD users are always lagging behind, this had been the case for many years. Just recently they brought FSD up to current users for 12.3.6 so they could have show room cars ready for FSD test drives, but that didn’t last long when new bugs came out in 12.4 having to be canceled completely (even tho I have it and it works great minus speed control) and now 12.5 being slow to release. FSD lags behind again.

yay_cloud 2024-09-23 15:48

Yep, same for me on highway. Passing a car in the other lane, my car gets next to the car in the right lane, starts feathering and you feel it in your body. Odd pulsation. This is the first regression I've experienced sadly.

[deleted] 2024-09-23 15:50

Wave? You mean to 3 people?

JerryLeeDog 2024-09-23 15:58

Uggg still waiting on it on my 2018 Still have 12.3.6 woof

JerryLeeDog 2024-09-23 16:00

2018 M3P in San Diego... notta, zip, zilch, still on 12.3.6 and was getting skeptical haha

imacleopard 2024-09-23 16:01

The hell it does. Does for 30 seconds and then wants to go back to whatever speed it wants to, often dangerously lower than surrounding traffic.

mrbeez 2024-09-23 16:03

me also

thomasbihn 2024-09-23 16:05

It is outright dangerous to use in my area. I had a firm grip on the wheel and foot hovering and still about had a heart attack when the car would've crashed last time I tried it. If it would just maintain speed, I'd at least use it on long stretches and just disable it on turns, but that was last an option on v11.4.9, which I really miss using.

MonsieurVox 2024-09-23 16:24

I just got 12.5.2.1 this morning. Looking forward to the version with ASS and nag-free sunglasses! Those will be some very nice quality of life features, especially being able to wear sunglasses. I can’t imagine too many scenarios where ASS would be practical outside of simply showing it off, but it’s an awesome feature nonetheless.

jedi2155 2024-09-23 16:27

It's more like they're trying to capture user data for to continue to refine the AI models. Designing AI Models is not like traditional structuring programing/feature implementation but requires a huge degree of user input to refine the output.

[deleted] 2024-09-23 16:28

The highway is using the old V11 code though...

yay_cloud 2024-09-23 16:33

Yes, true, but something got worse. I drive the same route twice a week and started getting bad behavior. Some highway spots, that for last 2 years have had no issues, suddenly phantom breaking and no one is around. This would be a 4-lane highway, 2 on each side.

cereal3825 2024-09-23 16:39

The pulsing is driving me nuts. I thought I was crazy, good to know others have the same issue.

CleverUserName1980 2024-09-23 16:42

100% agree. Just did my first drive post update. It changed lanes 3 times no signal. One time signaling to go back to the lane it changed from within 5 seconds. Jittery acceleration. It just seemed very unsure of itself.

technolgy 2024-09-23 16:46

It has not been this way from the beginning, not to this extent certainly.

[deleted] 2024-09-23 16:54

Maybe V11 is not as stale as some are saying...

RyanBorck 2024-09-23 16:59

I meant it’s always been endangering people. It’s literally killed people. I say this as a fan of Tesla and FSD.

[deleted] 2024-09-23 17:10

Not me on HW3. It looks like it moves at the average speed people are going on those roads. On a 70 km/h road, it drove at 80 km/h on the left lane, passing cars on the right lane. On a 60 km/h single lane road, it followed traffic, ranging from 55 to 65 km/h. On a 50 km/h road, it drove at 60 km/h (acceleration was smoother than 12.3 too). On my neighborhood 40 km/h roads, it drove at 30-35 km/h. I'm fine with that since that's the speed most are going on those narrow neighborhood roads.

skottydoesntknow 2024-09-23 17:11

The vision monitoring with sunglasses in 12.5.2.1 doesn't work, was a bit disappointed. Message pops up saying sun glasses detected vision monitoring off

hoang51 2024-09-23 17:14

2020 M3P installing 2024.27.10 with FSD [12.5.2.1](http://12.5.2.1) at the moment. Coming from 2024.15.15 with FSD 12.4.3.

ChemistStrange6801 2024-09-23 17:15

Ya its not in that version only in the new 12.5.4 that was first seen this morning.

skottydoesntknow 2024-09-23 17:16

I misread the release notes that it was upcoming. Usually just says what's new not the road map. Thought I was going crazy with it not working

Lokon19 2024-09-23 17:18

12.5.2.1 never came with sunglasses monitoring.

Artistic_Okra7288 2024-09-23 17:28

I can't drive anywhere without switching between the hardcoded highway stack and the city streets stack, so I am very happy to say Good Bye! to 12.3. 12.5 fixes to many issues I've had. Seems like 3 steps forward and 1 half step back instead of the usual 2 forward 1 back or sometimes 1 forward 1 back.

MisterTwo 2024-09-23 17:33

I’m glad to hear that! 12.3.6 worked great for me so the speed thing is annoying but I’m sure it will get resolved.

TheGoodOldCoder 2024-09-23 17:36

I don't know the exact way that they determine speed, so I use "implemented" as a catchall that includes AI training or hard coding or whatever. I'm pretty sure that you don't know exactly to what extent AI is used for speed, either, so it's a bit of a silly objection on your part. Anyways, if you know a better catchall word, then I might start using it. But importantly, I am not involved in the development of this feature. I am simply a user, and as a user, the important thing is that this behavior has significantly regressed. It used to be completely reliable, and freed up some of the driver's attention to make the entire experience safer. Previously, if you set a speed, it would quickly achieve that speed unless there was a reason not to. With this new behavior, it is actually more distracting to me than using the accelerator to keep the speed manually, which I would categorize as making the entire driving experience more dangerous. And on top of the safety feature, like I said, as a user, I feel like they have broken a feature that used to work much better. A traditional cruise control function would be preferable to this. Terrible practice.

Small_life 2024-09-23 17:40

I got [12.5.2.1](http://12.5.2.1) on 2020 M3 RWD this morning. Haven't test driven it yet.

Artistic_Okra7288 2024-09-23 17:56

I still have the speed thing, but it's really just an annoyance at this point on 12.5.2.1 (at least where I have been driving). Hopefully they will get back on faster release cycle and that'll get squashed for good. Looks like the lull in releases is from Cybertruck FSD support and upcoming Robotaxi. Now it makes sense when they had to add in HW4 API calls into HW3 (emulated). They were spending so much resources getting FSD working on Cybertruck (HW4+ only) and (hopefully) Robotaxi (again HW4+ only). I'm hopeful they expend some resources to get a robust HW3 optimization pipeline going so we get the releases as quickly (or soon after) HW4 does.

modeless 2024-09-23 18:02

Just chiming in to say that the speed control in 12.5 is not bad for everyone. I've found it to be pretty good in my area. It doesn't always go the speed limit and that's a good thing. For me it generally makes good decisions about when to go -5 or +10 MPH. I find 12.5 to be a huge upgrade over 12.3 in every respect. It's a far better driver. 2018 Model 3 with HW3 here, just upgraded from 12.5.1.2 to 12.5.2.1 this morning.

12.3 slams the brakes for crosswalks in my neighborhood when nobody is there

Marathon2021 2024-09-23 18:27

> minimally feathering the pedal constantly Oh god. They trained it on *my wife’s driving*!! I’m so sorry everyone … :D

icy1007 2024-09-23 18:54

Yep, I got this update last night for my 2024 Model 3. 2024.27.10.

icy1007 2024-09-23 18:54

Pulsing? I haven’t seen that with my Model 3.

metaxaos 2024-09-23 18:57

Is this finally the same model for HW3/4, or there are still two different in the same package?

nyrol 2024-09-23 19:08

12.3 never did that for me. 12.5 does it all the time

nyrol 2024-09-23 19:09

Happens on my model 3. HW3

[deleted] 2024-09-23 19:10

How about just using the input that I set the speed to 50? How does the AI learn anything by reducing it to 43 until I notice it still isn’t going fast enough and step on the accelerator until it gets up to the speed I already told it I wanted to go? Is it testing me to see if I really meant it? This has been a royal PITA on secondary roads for the past four or five months.

[deleted] 2024-09-23 19:11

Apparently they are ignoring the 50 year old algorithm of simple dumb cruise control to hold a set speed.

Mithious29 2024-09-23 19:17

It only does it when I’m on roads with no centerline, like my neighborhood, normal city street crosswalks are fine

nyrol 2024-09-23 19:38

I’ve had it happen even with a centerline, just yesterday.

CarCooler 2024-09-23 19:46

Nope, single HW3/4 stack should be 12.5.4.

[deleted] 2024-09-23 20:09

This was what I figured. It makes sense. Frustrating but understandable. It never bothered me until I could play YouTubemusic natively in one car and not the other. A minor inconvenience at a premium cost.

icy1007 2024-09-23 20:20

I've got a HW4 Model 3. Maybe that is why.

vkp7 2024-09-23 20:22

How do I find out if I have HW3? For context: I went through the EAP to FSD upgrade ($2k) on my 2018 Model S.

metaxaos 2024-09-23 20:29

So it's indeed 2 models packaged in the same deliverable? Did we get any official updates on this after that last tweet from AI head on how they were trying to add some functions to the compiler?

VideoGameJumanji 2024-09-23 20:39

You guys lmao, every single update it's the Andy toy story meme immediately

VideoGameJumanji 2024-09-23 20:41

You should still keep your hands somewhat on the wheel.  FSD is amazing, but other drivers are not and your reaction time plummets exponentially with your hands off the wheel.

Den_Ouwen_Belg 2024-09-23 21:13

So, does this version actually work in Europe? Or are we stuck on the old FSD’s?

HubertGavin 2024-09-23 21:55

Today, get 12.5.2.1 finally for hw3.

silvanus22663 2024-09-23 21:58

Based on car name, A-Z. Mine is red and named it Zoidberg. I’m never gonna get the update. ![gif](giphy|d1tlu8P8b5FkY)

VLM52 2024-09-23 21:59

Pretty normal. Rollouts are gradual and they'll happily pause a rollout or skip it entirely before it hits the entire fleet if there's something they don't like about it, or if they find a low frequency regression that wasn't caught in testing.

Robert_Cutty 2024-09-23 22:00

If getting ass was a software update, why the hell did I spend all that time and money on dinners

thomasbihn 2024-09-23 22:03

I find it to go between 50 and 52 in 55 zones. I don't really use it in town because it doesn't work well in my little town. v11.4.9 didn't have this problem. I wish they'd give an option to roll back. :(

reefine 2024-09-23 22:31

100% agree, 2016 Intel Atom Model S with HW3 and updated cams

DaffyDuck 2024-09-23 22:33

I want to know this too because 12.5.2 after having 12.5.1 on my HW4 Y feels like a smaller model by the way it behaves.  Phantom breaking is back.  I feel much less comfortable using it and I’m hovering my foot over the accelerator much more often.

[deleted] 2024-09-23 22:33

Say what? Does this mean you cant use fsd while wearing sunglasses on that build?

skottydoesntknow 2024-09-23 22:37

I misread the release notes after it installed. It mentions sunglasses but says it's in a future build, I missed that part of it. Eye monitoring works decent but a bit too sensitive to looking away, I think I prefer the steering wheel nag tbh

metaxaos 2024-09-23 22:48

Something tells me we'll never know, and the official answer would be "you see, same number, same version, duh".

E_lonui7xz 2024-09-23 23:14

I’m waiting for an update for so long, stuck on 12.3.6. Is there any way to force update the car? I am in Canada.

[deleted] 2024-09-24 00:31

Hmmm this could be a deal breaker for me… currently if I wear sunglasses I get zero nags when glancing at the screen or out the window

ButMoreToThePoint 2024-09-24 01:37

You can, with same steering wheel nag as before.

mensrea 2024-09-24 06:52

I’ve had FSD since 2021 as well. At least since 10.3.1 on two different vehicles. My wife got 100% score before I was able to so she got it first. My wife still has her model Y, I first got FSD on my 2021 model three performance and last year swapped that over to a 2023 Model S plaid.  So, I’m running it on HW4 and I haven’t seen that. My wife doesn’t have it on her MYLR. My dad does have it on his HW3 ‘20 MYP, so I’ll check in and see what his experience has been. Sorry, you guys are having issues.

ebikeratwork 2024-09-24 20:18

I got [12.5.2.1](http://12.5.2.1) yesterday. Honestly, I preferred the FSD in the 12.3.whatever I had prior to this. [12.5.2.1](http://12.5.2.1) is really aggressive, making last minute lane changes, brakes really hard if there is a slowdown ahead or a biker that is well inside his/her bike lane. 12.3.whatever was a much better driver, and it got me to work most days with almost zero interventions.

oz81dog 2024-09-24 21:15

still 12.4.3...feels like a really long time on this version. It has so many bugs i barely use it compared to earlier versions. Not honoring the manual speed limit control and the inability to go the fricken speed limit make it useless. It's either racing up to 50 in a 35 zone or going 45 in a 55. Garrr, it drives me nuts.

Jimmy_Durango 2024-09-25 03:14

I’m not getting any updates ☹️

TheFlowChartKen 2024-09-25 06:31

I lol’d. gosh, I’m going to hell, huh?

OrganicNebula 2024-09-25 14:17

Got 12.5.2.1 on my Plaid yesterday, man it’s terrible. Moves into the right lane .2 miles before a left turn, thinks bus stops are turning lanes, freezes in intersections when it can freely turn left, can’t merge onto a freeway behind a truck, drives incredibly slow. I could go on - it’s truly horrendous

VideoGameJumanji 2024-09-25 14:54

I'm getting that as it passes some intersections on 12.3.6, it definitely started there, I didn't see that behavior at all on the v11 highway stack that currently exists.  Glad it's not just a me issue either lmao

VideoGameJumanji 2024-09-25 14:55

Bruh still waiting my 22MY. And to think I was going to get this "anytime now" for my road trip at the end of August lmao

CarCooler 2024-09-25 15:40

Hmm... other owners, please testify.

HermitageSO 2024-09-26 16:34

FSD apparently can see deer now. I was driving last night with 12.5.4, and before it wouldn't recognize deer, and this time a buck stepped into the right of way, FSD slowed down dramatically, which was absolutely the right thing to do. Pogress!

CryptographerDear250 2024-09-26 16:37

nice! still twiddling my thumbs but happy to wait for a stable build. thanks for the update, looking very forward to it.

DNAPoPo 2024-09-29 00:37

Ya, got 2 in a row, boosted to 12.5, then 12.5.4 right after!

kevosauce1 2024-09-29 16:05

Finally got it on my 2020 MY after being stuck on 12.3.6 forever! Woohoo

CarCooler 2024-09-30 03:24

Cool.

OrganicNebula 2024-09-30 03:35

Following up that I got 12.5.4 the very next day which has been great lol

IMissDrYfantis 2024-09-30 03:44

I suggest not to set “automatic set speed offset” for 12.5. It is going a bit unstable and speeding on the high way

Climactic9 2024-09-30 06:51

Hell? For making fun of a bad driver? If that’s your greatest sin you’re going straight to the top floor of heaven.

False-Video-7121 2024-09-30 09:56

I got the 12.5.4 update but it got stuck in download at 50% for a couple days. Then it disappeared on day 3.

Own_Performance_2789 2024-10-01 10:27

Thank you. I thought I was going crazy. Feathering and going well under the speed limit on side streets too. Big step backwards.

Own_Performance_2789 2024-10-01 10:29

Agreed. I can’t use it right now. It is dangerous.

Kajaah117 2024-10-24 15:51

In the interest of good science, I'm sharing my similar experience. 2017 Model S Acceleration on city streets is constantly surging as you've described. Noticeably worse at determining the correct lane to be in to turn at a lot of my local intersections it had no issues with prior. Phantom breaking EVERYWHERE. I no longer use it at all when I have passengers. It's embarrassing at best, dangerous at worst. *Quick note: I noticed that when it's doing the acceleration surging, I have text on my screen at all times that says "use turn signal to cancel," but there's no action being taken other than driving straight. It's almost like it's in a constant state of preparing to make a lane change that it never does.

LurkerWithAnAccount 2024-10-24 17:38

And one more anecdote that my wife’s 2021 Y with HW3 is noticeably better on all the same routes. Our cars are both on 12.5.4.1 now and hers still has a bit of jerkiness, but is otherwise quite good and usable. I agree that I can no longer use 12.5.4.1 on my S with passengers, I can put up with the annoyances for now. Of course neither vehicle can hold a candle to the Cybertruck on HW. Even though I understand 3/Y are even better, the truck is night and day better on all the same routes. Here’s hoping Tesla can at least smooth things out like they were before 12.3.6
