I've been considering an EV, but this got me to look at the break even point for how much I actually drive (5,000 mi / year), my gas mileage (30 mpg), my offpeak power costs ($0.20 / kWh), and typical gas prices here ($4.50 / gal). It would take me about 20 years to save $25,000, which is about the difference between my current car and a Tesla. That said, I probably shouldn't consider a Tesla, since it occasionally snows pretty hard here in Northern Nevada and the Tesla's snow handling is not the best.
