Of course we've discussed this several times, but I don't think the general public is aware of diminishing returns or how this measure of fuel economy isn't intuitive to understand.
Much more important to figure out how to get a 15 MPG vehicle to get 20 MPG than to figure out how to get a 50 MPG vehicle to get 55. I basically don't care if the Prius ever gets better fuel economy because the difference between $0.06 per mile and $0.055 per mile isn't that important to me.
