Hybrid operation strategy

The Eco cruise does improve the mpg performance by increasing the speed window for cruise control.  It could do even better if the window (speed below the set speed below which to engage the engine) could also have a program that would increase the window to about 6 mph rather than the approximately 2 mph.  This would allow a simple way to implement "pulse and glide" for high speed highway travel.  This would provide better highway mpg numbers simply.
