I was hoping to just see a possible adjustment in the programming that would allow the speed to vary more than it does stock. Instead of trying to maintain a speed +/- 1-2 mph, allow the speed to drop a little more (3-5mph) before the cruise would force the speed back to set point.
This is like the way I drive without using cc.
Loosen up the allowable variance from set point.
Possibly have a selector switch that would allow the user to chose between maintaining speed as first priority, or ECO mode which would allow more "slack" in the program so to speak, (less aggressive mode.)
