How is BlueCruise supposed to work?

[WilliamRobert]

Predictive speed control, the new update, is on my Mach e but not on my Lightning yet (never I hope). The lightning reads speed signs and is very accurate, the Mach e is doing better but the first few weeks it was reading mile marker signs as speed signs and would jump to 60 in a 40 zone, also when in a 55 zone and a turn was coming up, it would knock off a ridiculous 5 mph when it was totally not needed. Hopefully ford will fix this before too many people die, but you know how hard it is to convince an engineer that they are wrong!

= turn OFF "Road Sign RECOGNITION" feature
= realize that BlueCruise is not perfect for the 'whole' trip, even on roads it says are 'BlueCruise' roads.
It is constantly 'searching' for all the aspects of the roadway it expects as part of it's protocol - if even a single one is 'missing' or not confirmed, it disengages and requires the driver to 'take the wheel'.

Now, many of us have only the 'entry' version of Automated LANEcentering(which I upgraded/added myself, to my basic PRO Lightning), which constantly requires 'hands on' at periodic 15-20 second intervals, no matter WHAT type of road you are driving.
I have overcome this constant annoyance by simply adding a 1lb 'wrist weight' strapped to the 2-3oClock position on the steering wheel. The truck works FLAWLESSLY for hundreds and hundreds of miles like this.

This is great Do you have a picture of this contraption?

Blue Cruise has a limit on how tight a curve it can take, here is the bc map from ford with a curve that isn't exactly bc capable. Check the bc map from ford for your area.

I gathered that from its behavior. Do you know what the criteria or methodology is? Most of these curves are gradual, not places where I would slow down, and the lane keeping and follow distance still works. So I'm a bit mystified why it suddenly wants me to keep my hands on the wheel. Seems to me like it could use a few more passes, but maybe there's something I'm missing.
