You may be past the point of interest in EVs but I wanted to to toss out something with respect to the Leaf's range.
I've been messin' around with range extender trailers since the 90s.
Right now,BamZipPow's T-100 Toyota,with 1-wheel teardrop trailer is picking up 2-mpg by pulling the wake reducing trailer.He's one of the few in history to do this.
It seems that a perfectly integrated,gap-filled, boat-tailed trailer could be used as a Battery E V range extender.
Here's Alan Coconni's t-zero modified:
Between now,and when Elon Musk comes out with an entry-level Tesla,a range extender trailer would be a way to reduce the drag of the EV,thereby extending the range of the EV's battery pack,and with a second pack inside the trailer,more that double the range,say, 170-miles or so with the LEAF.
