Nobody is trying to insult your intelligence. You’ve posted a question to which you don”t have the answer to a group of others with a vast amount of experience with the issue you’re having a problem with. You need help and we’re offering it.
So here’s another idea to which I hope you don’t take offense. Have you actually checked that setting since you posted the question? I’m sure you’ve seen others post about how settings sometimes reset themselves after OTA updates. Maybe that’s what happened? I honestly can’t think of anything else that would change the car’s set speed from 75 to 85 with no intervention other than speed sign recognition, well other than tapping the “cancel/resume” toggle while going 85, but you would have had to accelerate to 85 with your foot to get there.
Yes, I rechecked the setting. Still off.

I tend to believe that this isn't what a "others with a vast amount of experience with the issue you’re having a problem with. "

Whereas I personally have had the experience of the change in speed because of the speed limit sign reading, in this case we are talking going from 75 to 85, while on BlueCruise, multiple times in a half hour without any signs to that affect and BlueCruise is limited to 80 mph.

This sounds different to me.

Going south through the Aurora/Alaska Way tunnel the speed limit is on a screen, and usually 45mph. The car thinks the limit is 40 until almost the end when it speeds up to 60. There is nothing in the tunnel that it could be read as any number in that section of the tunnel. I suspect a Ford map error.

ps - anytime I feel any unintended acceleration I glance at the speed limit which is in small type upper right-hand corner of the smaller screen in front of the driver.

Just meant that the group has a vast amount of experience with the car - just the kind of group that you want to present your problem to. Maybe some one of the bunch has even seen the problem but so far it doesn’t look like it.

Blue Cruise is limited to 80 mph but adaptive cruise control isn’t.

Sounds like a glitch, …, or a malfunction. If the speed recognition is off and no buttons are being pushed, the car shouldn’t be switching the set speed on its on.

It's not BlueCruise having the issue, since it doesn't work above 80mph. Nor has the OP used the term, BlueCruise. Only you did.

I'm waiting to see all the settings, because sign recognition coupled with the buffer is where I'm placing my money, despite OP's protestations that it's not that. No reflection on OP, I'm just wondering if we're talking apples and he's talking bananas on a specific setting.

In 4+ years, I haven't seen a single report like this on any forum or FB group that wasn't those settings.

10 mph or more should always be accompanies by an auditory signal.

The screenshot doesn't show your tolerance setting. Can you open it up to verify?

I was, in fact. using BlueCruise at the time of the speed changes. I felt the sudden speed changes and immediately shut it down. Reset it, as I said previously, 3 more time, making sure I wasn't hitting any controls that could cause the speed change. I have used BlueCruise on both my MachE's and have never had this issue. I experienced the sign recognition issue almost as soon as I had purchased my 2021 Mach E (first addition) and after finding out what was causing the issue, I shut it off. It's a liability that ford should never have built into the car. And, clearly, should have not been set by default as on. That should be a driver choice to make. No one at the dealership could explain why the car accelerated like it did. I had to research it on line.

I opened it up and verified that it was set to 0. I took the picture after closing it so as not to interfere with the other sittings in the pic. That would also not explain the sudden change in the cruise control setting change from 75 to 85MPH. I also don't think the tolerance adjustment is even close to 10 MPH ( if I remember correctly)

You have Predictive Speed Assist on. You need to turn it off.

This is a result of your newer car having settings your older car did not, because it's more updated. As I said, totally explainable.

You might want to go back and read your posts in this thread, the responses, and now the reality that it is in fact you not knowing what the new setting does that caused the problem.

Tolerance is set to 0

I thought before you said that Predictive Speed Assist was off. With it on, and with a tolerance of zero, if it thinks that the speed limit has changed, either by seeing a speed sign or by what it has in its map data it will change to that speed.

Also, at this point it isn't clear if you were actually in BlueCruise or Adaptive Cruise control (EDIT while I was posting this you clarified that it was BlueCruise). BlueCruise is limited to 80 mph, but Adaptive cruise isn't.

Personally, I have Predictive Speed Assist off. If I'm in "windy roads" I don't use either of these, as such I don't count on them slowing me down in curves and speeding up afterwards. In other "straight highway" situations I want to be the one that changes the speed.

And how would that change the speed setting from 75 to 85 MPH? My interpretation of the predictive speed assist is to slow down the car when approaching curves and exits. NOT to instantly reset the speed. There are no 85 MPH signs anywhere in this state. Are you saying the car misread signs 3+ times in 30 minutes? If that's the case, the system is horrendous and should be deactivated from all cars. And yes, I was CLEARLY using BlueCruise unless Adaptive cruise control allows me to drive hands free for miles and all the blue indicators on the dash are completely wrong.

Not totally explainable. In no way explains the car resetting the speed from 75-85 MPH when using BlueCruise. That makes no sense at all.
