The cruise control has some quirks, but the overall design approach is excellent. None my previous EVs with adaptive CC let you fall back to regular cruise if something went wrong with the front sensors (dirt, snow, etc). We have: selectable Cruise Control (just maintains a constant speed), Adaptive CC (maintains a gap, probably radar and camera), and intelligent CC which adds in auto speed set by reading the speed limit signs.
The intelligent CC is really interesting. It could be a blessing, like on two lane highways that keep going back and forth from stretches 55 mph, then down to 45 mph, and finally 30 mph through the center of towns. But, it can be disconcerting if you are moving along as some mph above the speed limit and it reads a speed limit sign, at which point it reduces the speed to the sign speed.
You can set a "delta" from the marked speed, Ford calls the CC tolerance, but that tolerance then applies everywhere. For example, around here, 72 or 73 is pretty safe out on the thruway. Around 75, especially if it is quiet, you can get pulled over. (I know 80 is normal in a lot of places, but not here.). So, I could set a CC tolerance of about 7 or 8 for the highway (65 + 7 to 72). But, then if I use the intelligent CC on a local road that is 40, it would read the sign, and immediately set 47, which in this town might get you a ticket near residential neighborhoods, where 42 to 44 is probably safe. So, the bummer is that one might have to be constantly tweaking the Intelligent CC tolerance, or just set it to zero, set your desired speed up as desired, but then you have to do that every time it sees a sign!
Or, sometimes, just drop back from intelligent CC to adaptive CC.
So, it's pretty cool. [Probably] You can use CC even if the gap sensors fault, and it can read signs. I think the next step is the ability to set different tolerances for different speed ranges, or maybe a % of speed, instead of mph (so more delta at higher speeds, less at 30 or 40 mph). I suppose it should be possible to set desired tolerances by certain roads, stretches of roads, highways, etc. too.
