I agree. The Clarity displays are lacking as compared to the Volt. I don't reset the Trip A odometer. Then under the Info in the Home Menu, you can select Trip Computer, then select History of Trip A. This shows total miles and MPG for Trip A. If the MPG is 199, then that just means that the calculated MPG is 199 with no cost for electricity. Since the gasoline MPG for the car is 45-50, that means that you are running at least 75% electric. Not a ton of help unless the number is less than 199, then you can get a pretty accurate guess about electric/gas. If for example it shows 90-100 mpg, then you are running pretty much 50% electric and 50% gas. Since I know I run more like 85-90% electric, I have to keep up with gas purchases. The car started with a full tank of gas. I've bought 4 gallons and stapled the receipt to a page of paper on which I wrote the date and amount of gasoline purchased. I plan to just keep up with all the gasoline I buy like this. The tank is half full now, so in total for 2400 miles, I've burned about 7.5 gallons of gas. So I'd estimate my gasoline miles at 7.5x50mpg or 375 miles and electric at 2025 miles.
