on very hilly roads, I like to hit the crest of the hill at least 10 mph below my target speed so I don't have to ride the brakes all the way down. imo, this is fine as long as you don't do it in the left lane. my car has a standard transmission so cruise control isn't super useful in this situation anyway, as I tend to change gears a lot.
