So, if you charge to 100% then FSD will not brake?
FSD does not care about the mode or regen. It requests deceleration and the car decelerates.

Hi Dewg. I don’t see that option under navigation or autopilot. What am I doing wrong?

"whereas power used by the regular braking system displays in gray."
Ok. Tesla does not always document everything. But here is how it works (approximately - any uncertainty is noted in line). I would do pictures but I keep my car at low SOC and I don't live in a refrigerator so I can't display what is needed.
If that "Apply Brakes When Regenerative Braking Is Limited" is DISABLED:
When NOT using FSD:
- If you have limited regen, you will see dots on the left hand side of the bar. This indicates some level of limited regenerative ability.
- When you release the accelerator, you will have limited regen. This may result in less slowing that you are accustomed to, depending on slope, how long you have been regenerating, etc.
- You will see green on the bar to show you your regenerative power. It may not be able to make it all the way to the dots depending on your speed, but you may still notice reduced braking even if you have not technically hit the regen limit, according to the bar.
- When you use the friction brakes manually, this will not display on the bar in any way.
When using FSD:
- Even if you have limited regen, these dots will disappear when FSD is in use.
- The bar that shows regenerative braking will only show regenerative braking in green.
- When FSD uses friction brakes, it will not display on the bar in any way.
If that "Apply Brakes When Regenerative Braking Is Limited" is ENABLED:
When NOT using FSD:
- If you have limited regen, you will see NOT dots on the left hand side of the bar. This is because limited regen does not matter; you don't need to know about it.
- When you release the accelerator, with limited regen, you will have limited regen. However, the brakes will be applied, and you will feel this if you cover the brakes. You will get the same braking behavior and "regen" profile as you would if you did not have regen limits.
- You will see green on the bar to show you regenerative power.
- With accelerator pedal released, you will see black on the bar to show you how much friction braking is being used (blended).
- Manual brake application is not displayed on the bar in any way.
When using FSD:
- The bar that shows regenerative braking will show regenerative braking in green, and friction braking in black.
- If regenerative braking is limited, it will display more friction braking than it would otherwise.

As explained above, this setting affects behavior when you drive manually. It has no impact on decisions by the computer when using FSD Beta.
where in the manufacture's documentation does it say that? It does not. Trur that you don't see the 'gray' ever show up when not in FSD. ALso irrelevant given this whole sub-thread has to do with FSDs braking using physical brakes or not.
What I do see regarding this original bit are a lot of claims that are not backed by anything other than the poster's claims and that are contracicted by documentation.
Time to stop arguing. I'll continue to believe the manufacturere's word for this which also matches my experience.
Have a good rest of your weekend everyone.
@Webeevdrivers I had an experience on FSD v12.3.6 that I think you will appreciate: At a four way stop it came to a stop, then started to proceed, stop, start, stop, start, etc. At first I couldn't see what was causing the problem, but then I looked up and saw a flashing red light, which it was going in sync to. (I think trees were blocking my view of the red light as we came up to the stop.) I disengaged and reported it.- On a flashing green arrow or light the car starts and stops in sync with the flashing. It’s hilarious. Takes a long time to get thru an intersection. Usually about 8 flashes.. And we have those everywhere here.
Weirdly I went through three more intersections with the same setup and it did just fine. (But none of them had trees blocking the flashing light from a distance.)

Where do you have flashing green lights? I’ve never seen that in any of my driving anywhere.
Flashing red is used as a stop sign, flashing yellow as caution/yield, but what exactly is flashing green supposed to mean? It seems to be a non-standard use so I’d understand why FSD gets confused. One second the light’s green, the next there’s no light at all which generally means stop and proceed with caution because the power is out.
Canada.
What do blinking green traffic lights mean in British Columbia?
Flashing green traffic lights don't mean the same thing in Vancouver BC as they do in Ontario or the US

like this?
I go through this one all the time and FSDs handles it fine. Slows to the stop, maybe creeps a little and then goes. This pic is an old one. Now that stop sign on the right has small lights around the edge (as does the right hand one coming the other way). Those lights blink continuously and the car handles this one fine.
Have to double check but I think these are regualr old lights. Not LED

I believe this may be true in manual mode, which contradicts the documentation, arguably. (Anyway irrelevant here as you say.)
As suggested, charge to 100%. Try using FSD with and without the setting. Observe the regen bar. Report back!
You don’t have to believe me. You can check it yourself. Let me know.
I think you will see mostly black/grey with mode on when slowing modestly, and you’ll see nothing except a tiny amount of green with the mode off.
This doesn’t exactly prove things, because in these modest situations maybe brakes would not have been used and theoretically it might only display brake use when it would have used the brakes regardless. But it doesn’t work that way it turns out. That’s why just going to an unlimited regen state and observing the brake pedal is the way to check this for sure.
Where is it contradicted? The documentation says:
"whereas power used by the regular braking system displays in gray."
Do explain what is contradictory.

Yep, but like I said the one it had a problem with had the flashing red light blocked by trees as you approached the stop sign, you really couldn't see it until you stopped. I think that is what caused the problem.like this?

Sure, it is non-standard in the USA. But it is standard in some other places, and if FSD is allowed to be used in those places, it should respond appropriately to flashing green when the car is in locations where flashing green has a specific meaning.

Yeah I had this happen on the approach to a disabled traffic light, flashing red, on 12.3.4.
But rather than coming to a stop, on the approach it would slow down, then stop slowing down, then slow down some more, etc. With about a 0.3s lag, approximately.
I disengaged & reported.

except it's not even standardized in Canada. so you're expecting it to deal with an unstandardized system. Good luck with that.
I was on Interstate 26 at night from Kingsport going to Asheville using the trial FSD and the car would change lanes for no reason. Did it 3 times. There were no cars, exit or entry ramps nearby. It was slightly foggy. Also I live on a narrow street and the car veered onto the neighbors driveway, went a little slow, 13 mph instead of the 20 mph speed limit, and turned too wide and went on the neighbors lawn. It's impressive but needs some work.
