How a 50 mph dedicated EV lane system could solve to cost-per-range issue with EVs

At 50 mph, the Mitsubishi i-Miev can go 70 miles on a charge, the Nissan Leaf 97 miles, and the Model S 300 miles.

Compare this to what those cars can do at a typical 70 mph speed: 260 miles range for the Model S, 68 miles for the Leaf, and 40 miles for the I-Miev. That's about a 15% range gain for the Model S, a 63% range gain for the Leaf, and a whopping 75% range difference for the I-Miev. The Tesla Model S's being a heavy and aerodynamic car factors into its inefficient low speed range and more efficient, relative to that, high-speed range.
