I wonder if you could sell an aftermarket gauge, with user setpoints so it makes an obnoxious sound if your instantaneous mpg drops below x, and makes really nice noises if you cross above Y mpg (user selectable, cat puring, sexy womans voice, sexy mans voice, etc). Instant feedback at two important points on the graph, don't have to take your eyes off the road, very intuitive, etc etc.

I hereby give permission for anybody and everybody to build and sell this invention for profit or otherwise.

Probably not even really a new idea.

Finest regards,
