If you have two cars, does one of them really need a 300mi range?? Lisa's POS Neon will probably do her for another 5 years at the rate she drives (commute 4mi each way, minor errands), as she makes me drive any time we travel together.. from road trips to across town for dinner.
I'm going to get her an electric next.. The leaf is the current front runner, perfect for in-town use. But who knows by the time she's ready for a car. If she took a long road trip alone to visit family or the like (perhaps a 1-2x/yr occurrence) she could drive my car and I'd keep her electric while she's gone. I have 4 IC vehicles plus her car, I would LOVE to replace 50% or more of the fleet with electric.
As for the argument that electric isn't clean because of coal-generated electricity, that argument is a red herring, coal is dying quickly, and not for political or EPA reasons... Coal power is more expensive/less efficient than power from natural gas and too dirty to be a permanent fixture. Renewables are gaining price equity and acceptance rapidly, just not in the US.. We are lagging as the fuels of the future are being developed in Europe & Asia. There will hardly be a coal-fired plant left in 10 years and I say good riddance.
