Last time I counted it up, I figured it was around 21 cents per mile to drive my civic, and 11 cents per mile to drive my motorcycle, and so far it's cost me about $50 per mile to drive my electric car, mostly because when I figure in the cost per mile, I figure in the cost to buy the vehicle, insure it, license it, change oil, put tires on it, buying gas is only about 1/4 to 1/3 of the cost of driving a car that gets good mileage, I hate to think what it costs to drive a big truck.
