I would not expect that to be the case. If the price goes up, I'd assume it will go up for all users. Have you read something to the contrary?

FSD free trial. Very impressed. So better than Autopilot
- Thread starter rjpjnk

I'm new to Tesla, and find this hard to follow. I have a 2024 MYLR with H4.
1. So, if I use FSD during my three-month trial (which has about 2.5 months to go) when I am on a highway, am I am using V11, and when I'm on local roads, am I using V12?
2. If so, are both versions loaded all the time, or just when FSD is engaged by going to the second detent on the stalk?
3. What criteria are used to determine the version in use? Many of my local roads are 4 or more lanes, but are not part of the interstate system.
4. Is there any indication in the car that one version or the other is in operation?
5. If I use TACC (by going to the first detent on the stalk), am I actually using some V11 fsd code? If so, will TACC operate differently when my trial is over? (TACC is mediocre now; will it get even worse?)
6. What is the best recovery from phantom braking? Does lifting the stalk to the first detent disengage both fsd and tacc? (Brake tapping seems like a bad idea.) Is just pressing on the accelerator the quickest solution?
TIA for any answers you can provide.
So do you think there is a bug in the latest software that is causing the speed limit not to be recognized as well as it used to?
The App tells me I have 12.3.3. My right stalk works like my left one: half way down does one thing; all the way down does another. If I pull all the way down I'm in FSD, and the car drives itself. If I pull it down halfway, I get TACC. (or TACC and lane keeping if I don't have lane keeping disabled).
In other words, to engage FSD, I use the same motion used to go from park to drive.
FSD disengages when I override steering or hit the brakes. I have not tried lifting the stalk to disengage fsd. That is what I do to disengage TACC (or I tap the brakes).

That’s not how it works at all. None of the autopilot modes require a full press. It’s either single half press or double half press. FSD v12 has no more TACC unless you have disabled FSD.

Isn't that a setting? In my "EU FSD" car (so navigate on Autopilot is the highest available) model Y I have a setting to activate "FSD" with one or two presses.
You experience doesn't make sense. If you have 12.3.3 then when FSD is enabled you cannot get into TACC or AP without going into the AP menu and selecting one or the other (doing so disables FSD and you can't re-enable FSD until you put the car in PARK).
When FSD 12 is disabled and you have AP enabled you have the option to do a single tap for TACC and a double tap for AP. Once FSD is enabled you can't do that anymore (in V12). Also a half tap and full pull of the stalk are not different commands when it comes to FSD/AF/TACC.
Back to you original question, you can tell if you are running V12 city streets vs V11 highway by looking at the tentacle and/or using the AutoMax setting which will disappear when on a V11 stretch of limited access hwy.
Best recovery from a phantom brake IME is to just hit the accelerator.

The line extending out from the front of the car on the visualization.
1) It's not really FSD at all when on the highway, it's a version of an older product called Navigate on AutoPilot (NoP). It's a simpler product and has worked well for a number of years.
2) Yes, they both exist in the code
3) It's generally divided, limited access, 4+ lane roads. But it can vary a little.
4) When it switches, the visualizations change slightly and if you have the new speed control enabled, the speed will disappear.
5) No longer single or double clicks, just a single one now with FSD enabled or TACC.
6) Just press the accelerator slightly. SLIGHTLY, don't jerk he passengers around again, just a slight press and bring it up to speed, probably wait a few seconds and slowly release pressure.
BTW thanks for your time in answering these questions. I was using a full pull to engage FSD, because that seemed to work. Then after FSD tried to kill me the second time, I disabled it.
Then I noticed that a half pull would engage TACC. So, I concluded, incorrectly that there was a difference... and convinced myself, because it sort of makes sense: half a pull for just TACC, and a full pull if you want the full monty.
I did this today, prior to having read this. TACC seemed to want to hold a lower speed. I think I disengaged and reengaged at the desired speed. If I just accelerate to the original set speed does it resume without the disengage/reengage?
And thanks for your answers.
Yes. It doesn't tell you what highway version is running, as far as I know. You infer it from lack of changes plus the behavior of the maximum / auto speed limit. (A change there happens when you go on/off the freeway.)
FSD now just requires a single downward pull of the right stalk (on my Model Y) to engage once it is in Drive.
You look under Software in the car menu. You'll see version numbers there.
Not officially? The usual way is if you see Auto as part of the speed upper limit, I think that means you are on 12.x.
With FSD 12, you can't use TACC. You have to choose one or the other now. That did not use to be the case. I liked to have FSD disengage into TACC if (and only if) I'm on the freeway. That way it usually continues holding the current speed rather than dropping off like a stone. But in town the last thing I want on a disengagement is for the car to resume a speed. It would be nice to have the choice.
Just jam on the accelerator.
I have to say that since I've gotten FSD 12.3.x, I've not had a single instance of phantom braking. I've had some 'scared of that vehicle maybe coming into my lane' braking, but not like the shadow-induced stuff I used to get passing trucks.
Hope that helps. By the way, if you get into this FSD version testing/inspection thing, it's useful to have a test loop you can drive with each new version. It should, of course, have a few difficult spots. Myself, I'm installing FSD 12.3.5 right now, and in a little while I'll head out on my own 10 mile loop. I drive to a proposed Supercharger site which allows me to check for progress. I also test the Autopark feature when I get to that parking lot. I'm hoping it's faster as it's way too slow in a busy lot.
That's the second part of my response. It seems as if takes a little bit for the car's internal thinking of speed to some back up to the real speed. So wait a few seconds and slowly release the accelerator and see if it has caught up yet.
