I noticed that they only mentioned a 1 mpg improvement, but didn't mention the mpg number. Was it from 16 to 17 mpg, or maybe from 67 to 68 mpg?
Extrapolating, you could remove a mess of heavy sound insulating materials from the car, making it lighter, while the stereo still keeps it quiet. For you, at least. If the engine idles at lower rpms and produces uncomfortable noise, then that noise is audible not only in the cabin (where the audio cancels it), but around the car also. No noise cancelling for those around you on the road, in the parking lot, in your neighborhood.
On the side: it appears that lowering idle rpms can be stable and lower fuel consumption. This is good news for engine-on coasters. Wasn't there a thread on that? Can't find it, can't find it, can't find it!!!
