One of the few things I have found, lets' just say "less than perfect" on the Clarity, is the absolutely inconsistant driving score. I came from a Prius (Prime) , and spent a good deal of time playing around with "Hyper-miling" (doing absolutely everything at my disposal to see how far I get on a charge or gallon of gas.) The Prius has a pretty darn good score system (0-100) to help you along with this. When you really drive to eek out every mile, you get scores in the upper 80's-upper 90's. One thing i noticed almost immediately with the Clarity is that it's "score" with the Trees and 3 bars seems to have zero parallel with how economically I drive. Last night was the clincher. I was driving home from work late at night, and had the back-roads to myself, and on the highway few enough "obstacles" that I could really go, and not get hung up behind slow drivers poking along at 58 in the left lane. In a nutshell, I through all economy out the window and took the chance to really push the Clarity. High 80MPH all the way, touched 90 for the first time,. all on battery, which was getting eaten up at a far faster rate than I had ever seen before (I really am usually a very reserved driver) I was passing a lot, changing lanes a lot, and accelerating harder and faster than I ever have. When I pulled into the driveway I was ASTOUNDED to see a perfect driving score, with a medal awarded for the first time. ??? What gives? It was the WORST most ill advised and least eco friendly driving I had done in years!
