I just assume it's people not agreeing. The Leaf gets a bad rap, and a lot of hate. Nissan put a lot of great work into that car, and it doesn't get much recognition thanks to other developments in the recent years. They've been steadily increasing range (I think they're in the ~70mi range now), and have a much higher charging rate than others (Volt included, sadly).

If it wasn't for the guess-o-meter (range gauge) being so unreliable, and the degradation, I would have held on to my Leaf. But my range vehicle (an '08 Prius) was starting to need some more maintenance, and the Leaf became problematic if I needed to run any errands after work.
