voice activated fuel adjustment

As they have it on Indy cars, why cant we have a fuel adjustment on a passenger car. You already have a voice activated adjustment for your heat and aircondition, why cant someone develop one for air fuel mixture to help save gas. it could work like the cruise control, when one taps the brakes it shuts off. To reactvate just ask to go lean or go rich, and the computer could do so in minor adjustment .

Thank You,

The computer in the car does that already. There is no reason that you would want to run lean or rich. The fuel mixture has to be just right to burn. Indy cars use methenol which is different fuel all together.
