At least the field of awareness is expanding:
Automatic - Your Smart Driving Assistant
Driving Feedback
Automatic learns about your driving style and gives you subtle audio cues when you do things that waste gas, like:
Rough Braking
Braking abruptly decreases fuel efficiency and dramatically increases wear-and-tear on your car’s brake pads.
Speeding
Speeding doesn't save as much time as you might think, but driving 10 MPH over the speed limit reduces fuel efficiency by 12-15%.
Rapid Acceleration
Stepping hard on the gas pedal decreases fuel efficiency and wastes money.
Automatic shows how you're doing on every trip.
