In his latest video, Chuck Cook confirms that the latest software release (update: 2025.38.9.5) does in fact come with FSD version 14.2 and no new map update. He has yet to post his early review, but I’m certain we will start seeing videos from the early access testers shortly.
Chuck Cook Confirms FSD v14.2
- Thread starter Procal
- Start date
Looks like this build is trickling out, up to 7% today so far according to this site. I gotta say 14.1.7 did great yesterday for hours in the rain. Then at home there was a lane change in stand still traffic where it jittered like a kitten deciding which way to go 
. So bring it on!
. So bring it on!I'm still on 14.1.4 unfortunately, and the random braking is really starting to get annoying at this point. Hopefully I get 14.2 soon, as it seems to at least not occur as frequently on that version. I wonder if their goal is to get this out to more people and then start working on a 14.3 immediately in parallel with minor improvements to 14.2. It really seems with how quickly they went through the 14.1 branch that they are really trying to get that 14.3 out as fast as possible. Even chuck mentioned it in his more recent FSD video with the Juniper Model Y. It was barely a full week between 14.1.7 and 14.2, which would mean that they had to have been working on 14.2 for a while now.
It is intriguing the speed of changes, what’s going on and how do they do that? 14.2 is up to 10% now so keep hope alive! 14.1.7 was pretty smooth except for that crazy lane change. Wish I had it on video, super slow speed so the wheel jerks were fast and substantial.
Ironically, a few minutes after I posted this, I got the notification for the 14.2 update. Will update now and then review after tomorrow. I did notice in videos that 14.1.7 seemed like a very minor improvement over 14.1.4, so I am somewhat glad I didn't get that update. It really does feel like if they keep up this pace of updates we could actually be on 14.3 by the end of the year.
I got 14.2 tonight but I have been 1 weeks without FSD I got the warning my windshield needed to be cleaned . I made an appointment and when I left the dealership and hit the FSD the car dove to the right and was half in 2 lanes. I called the service number and was told the car needed to calibrate the cameras so I set it to run. A week later still not finished. The dealership is taking the car back on Tuesday. So I'll see if 14.2 fixes the leafs issue.
Ill update on Tuesday night
I also got the camera cleaning message, but it wasn't a warning. It was a long pop-up about having the cameras cleaned by a service center. I'm unsure why I got the message since I did the cleaning myself not too long ago, but apparently it is just Tesla reminding users to have the service performed periodically. I might have them do it anyway since it's free the first time.
So after the first day and a little over 50 miles on FSD v14.2 I have a lot of thoughts. I will try to keep it simple and short.
First, it definitely is a lot smoother, but almost feels like they severely pulled back the reaction time. It might be that they just smoothed it out and there is no added delay in reaction, but it certainly feels like it isn't reacting to things as “twitchy” as before. To the point that I'd dare say we are near FSD 13.2.9 smoothness levels.
Second, the brake stabbing and lane indecision seems to be “mostly” gone. I say mostly because there were a few instances where the car did behave differently than I would have expected. For example, there was a moment where a cyclist approached an intersection rapidly but turned onto a sidewalk. The car hit the brakes very aggressively, and even once they were past us, the car did some very minor braking thinking they would jump out onto the street. The lane indecision is where I think it improved most. On the highway, it wanted to switch lanes, but then hesitated for a moment. I tried to see if there was a reason for it, so I took a dashcam recording of it and watched it back. It turned out that the car didn't really hesitate, but had canceled the lane change due to a car in that lane speeding up at the last second.
Third is the speed profiles. This is where I think the most notable change happened. All the profiles with the exception of Sloth seem to have been dialed WAY back in terms of speed, and standard seems to have been also dialed back in aggressiveness. I spent most of my time between chill and standard, and now those two speed profiles feel like they are supposed to feel, in my opinion. Overall, they just feel more refined and like they react more appropriately to their surroundings, rather than just trying to go as fast as possible at all times. The other thing I noticed is that I no longer have the issue with it getting stuck at a certain speed. For example, on version 14.1.4 there were instances where if I entered the highway on hurry but then switched into standard, it would stay at the hurry speed rather than slowing down to the standard speed. The only fix for this was to either disengage FSD and then enable it again, or switch all the way down to sloth and then back up to standard to “reset” the speed. This appears to be fixed in 14.2 and haven't really experienced it yet.
Overall, this version does appear to be an improvement over the 14.1 branch of updates, and I could see now why Tesla feels more comfortable sending this out to more people. I do really hope that they didn't sacrifice reaction time in favor of smoothness, but only time will tell. It does feel like a definite upgrade from the version I was on previously (14.1.4) and I'm just glad I don't have to deal with the brake stabbing anymore.
Will update further if I find anything notable in the coming days.

I actually did watch it just a few minutes ago! Very interesting stuff and good to know that it can avoid accidents really well. I do wish they had tested 14.2 instead, but I understand that they didn't have access to it at the time of filming the tests. It would have been fascinating to know if there were any differences between the two versions. I'd also like to know if it would behave differently if there was a shoulder it could pull onto, or if it would avoid the grass at all costs.
