I agree as to what I would like. However the average tank and the inststant FE gages are adequate for driving with max FE in mind. The consumption monitor is a "scorecard" of a different sort. My belief is that it was designed because the computer monitoring needed is based on fuel flow and fuel flow is a mass flowed over time and the monitor is a cheap way for them to allow us to watch the computer's progress. had the made it a functiojn over miles then another interface would have been required and like most bean counters they might have just dropped it. I'm glad they added it but it can confuse people that don't understand that one minute at 60 miles per hour and 40 mpg only yields the same result as 2 minutes of 30 miles per hour driving at 40 mpg. It's not intuitive.
