Can you explain? You're talking about NOA on 2 lane roads, so you must be in FSD Beta NOA mode?
When you're talking about "slamming on the brakes" do you mean literally that, or that the car slows down?
What do you associate that with? Anything specific? What I've had is occasional slowing in reaction to nearby
cars or possibly threatening situations. The solution is to keep your foot by the accelerator when it might happen
and override it. I've only had actual braking maybe twice in 3 years of using NOA. I'm not doubting your report
but I don't understand. I never use TACC, so I dunno about that mode.

This is not phantom braking on the interstate, so Not while on NoA control. Remember the car switches to the 'old' NoA control instead of the new FSD when on 4 lane divived highways. That NoA still seems good on the interstate as far as false braking isn't a problem.
This is on 2 lane, non divided road where speed limit is 55mph so the new vision based FSD. I think it happens most at night when following a car in FSD and an approaching cars headlights become visible to the front camera as the approaching car on the left has its lights clear the car we are following. Like FSD sees the headlights of the approaching car on the left and thinks there is a danger. They are all well within their lane so no danger. FSD does a little slowdown or more aggressive brake apply about 33 % of the time this happens.
I tried avoiding this by giving some throttle with my foot. But after a mile or two of continuous foot pressure, the car bings at you to enforce that Cruise Control Will Not Brake. Wife commented this car is slamming the brakes or binging every miute. And Joe Mode isn't quiet enough either.
TACC is cruise control in this situation without auto steering, with a single pull of the stalk. Problem is braking and binging is identical, as just missing the steering part of the control.
Was annoying passengers so much I drove manually, no cruise, no auto steering for last 30 miles of the trip. What I would do for an option to just have normal old stupid Cruise Control.
And this Phantom Braking has been a problem TACC for years according to posts here. With Radar, now with Vision only this seems to be a Tesla problem they can't get a handle on.
If they can't fix the Phantom Braking, atleast give me to option to turn it off and let ME drive with simple cruise control. I'm not the first to ask for this.
