Depending on the circumstance, my cruise control is better than my foot WRT instant MPG. Driving on roads without much traffic and no real hills (not much of that 'round here, but it exists) then cruise is where it's at. Add traffic or some hill stretches for EOC or NC and then my foot is better.
Fortunately my cruise control isn't very aggressive, but it does tend to over-react to small bumps in the road.
