A always, a thorough, and wonderfully written article, Pritch!!
I, too, never liked hybrid brake feel, but can't argue that they still work. The first gen RX hybrid is awful.
And that is silly good mileage... But I've seen good mileage on long highway drives at 105. The fiesta managed 4.7-4.9L/100km consistently from Windsor to Guelph. The Corolla is in the low 5s at that speed, too. It's over you get to 115-120 that you see fuel economy tank. I wonder where the Prius sits at that speed.
