I have two cyber beasts. One is a foundation vin 39k and one is a non-foundation vin 49k.

Quick background, my 39k vin I use as my personal truck and use FSD regularly. The 49k vin is a work truck we use for deliveries and it rarely ever used for FSD. Both have about 10k miles.

After they both updated to v14 a couple days ago even the work truck was used in FSD a lot to experience all the changes with V14.

We are in a rural area and have had to modify maps, etc. to get the FSD working on our driveway.
This change testing was done mainly with the foundation (personal) truck. Even with v13 it navigated our driveway great after google accepted the map changes.

Now that we are on v14 - the personal truck is flawless crawling up the driveway and negotiating everything as it has done dozens of times.
The work truck not so much, on the exact same path it stops/wiggles the wheel and gives up before reaching the top of the driveway.
I figured it was needing a 'precision cleaning' for the FSD cams. I had that done a few hours ago at the service center and drove home on FSD.

Zero change - the work truck is like a lost toddler on the driveway. The personal truck still does it perfectly as it has for a few months.

This leads me to this post - is there a memory or some other sort of individual cache that each truck has and does it actually individually learn rather than borg style community learning?

Super curious and such a unique situation having two of the same trucks to see the difference with. (and knowing their historical differences)

Could this be the source of some saying v14 sucks and others say its so amazing? just thinking out loud here gang......

Interestingly I had a similar observation between our v14 model x and the loaner v14 x I got when they were working on my truck.
I chocked it up to maintenance issues but reading what you have to say I’m not so sure.

Might be related to a new camera calibration needed?
maybe - i thought it could have been the cleaning for the cams, but i have not done a calibration run on the work truck. will give that a shot this weekend - thanks

But the x I got wasn’t I assume a fresh install. Came with it already on it, so calibration should have been complete no?
Our x does curbside dropoff and pickup at the kids school (which is utter chaos) flawlessl, but the loaner just sat there confused and twitched its steering wheel.

SI now states to clear the front camera calibrations after cleaning. I’m assuming this wasn’t done?

I drove my beast tonight for the 1st time since 14.1, I also observed a little wiggliness but it was raining and there was a warning letting me know that there was reduced visibility.

I had an interesting experience yesterday. I used FSD to travel home and asked for driveway. First time turning into the driveway it did panic and the wheel studdered. Second time I was getting ready to disengage when it drove perfectly to my normal parking spot, and put itself into park. Could be coincidence or it is learning - maybe focused learning around destinations of interest.

I too have wondered. I have two entrances to the parking garage at my building and I wanted to see what it would do. going to the wrong one, I took FSD off and went where I was going.

how does the learning actually work if it does? I have subtly thought it can, but if you take of FSD can it still learn stuff? like should it be able to go to my favourite parking spot at the office? if you cancel its signal to change route, does that cause learning?

definitely don't understand but love it nonetheless!

Just a hypothesis but could be why the prompt after canceling FSD is no longer there.

You can hit the voice command and just say "report bug" and it sends in a bug report.

I've always wondered about whether there's any onboard caching that the vehicle uses. Anecdotally of course, I've often wondered why the first time I drive a new version of the software, it seems more hesitant; then, after it seems to get better. Why does its driving behavior change, unless there's some local learning going on? Always wondered about that.

I may be wrong, but I’ve felt for some time that there is individual learning going on, and here’s why. Our community sits just off a State Road where the speed limit is 55 mph. Whenever I pulled into the neighborhood—where the limit drops to 20 mph—the Beast would shoot up toward 55 until it saw the 20 mph sign roughly 100 yards inside the entrance.


I’d keep it in FSD and quickly spin the right steering wheel button down to 20 mph, and from there everything was fine. After several weeks of doing this, I noticed something interesting: the truck began slowing to 20 MPH on its own while the display still showed 55 mph as the limit. That behavior stayed consistent until we upgraded to V14, which started prompting me to use the scroll wheel to drop it into Sloth Mode (Sloth = Speed Limit).


Today I’m going to run a test to see whether the truck has continued learning or adjusting its assumptions about our local speed limit on its own. It’ll be interesting to see the result—but in my experience, it did learn the proper speed for our community.

The brain behind FSD xAI could/should be learning about our unique situations. The truck likely has cache memory. We may have the option and don't know it to help our Teslas learn. I wonder if we could nudge the FSD using the go pedal when it hesitates and steering wheel roller wheel when the truck is indecisive like roller wheel rolled forward and use directionals when it needs to know which driveway or area to point to? There might be additional commands we could/should be using to help train the FSD.

Another example just came to mind. Last year I was using the X-Files LockChime from my USB drive. I used it all summer, then eventually pulled the drive out. Despite that, the truck kept playing the same LockChime… with no USB plugged in.


I mentioned it to a Tesla service tech, and he laughed. I told him I didn’t understand how it was possible without the drive inserted. He just shrugged and said, matter-of-fact, “It saved it. Memorized it.”


So between that and the speed-limit behavior, I can’t help but think there is some level of individual caching or localized learning going on.

So yes, try teaching it with the changes in Modes and gentle nudges, those continued gestures may individualize and customize your vehicle...it's worth a try.

I wrote cache and meant RAM memory. CT has 10MB cache and 256GB RAM. That's enough RAM to make stuff happen. The motherboard on CT's are outside of my tech knowledge though I believe the CT has an industry leader in motherhood.

I agree - another day of playing in each truck and they are like different kids....... I wish they (tesla) would share more info (albeit in a simple tech way) to enthusiasts like us
