In the day of ECU and automatic braking, why doesn't cruise control maintain speed while descending?
While not everyone lives where there are hills, this seems like a thing that would improve safety and speed limit adherance. I lose several hundred feet of elevation going from one end of town to the other, and being able to set cruise control, and trust it, would make a lot of things easier. Yet I have to either manually put the automotic transmission into engine braking or ride the brakes, which then removes cruise control settings for the flat parts that do exist. #cars
