Driving the Sparrow costs less than driving a gasoline-engine car. It has no exhaust pipe. It plugs into a standard wall outlet at our house. I haven't run out of wiper fluid yet. The legend that says electric is not in very big letters on the back of the car.
Questioners usually look perplexed and then start talking about kilowatts.
In fact, our Sparrow will go about 1 mile on a kilowatt-hour. Our electricity is moderately priced by U.S. standards, and our gasoline is fairly expensive. However, the Sparrow does not need oil changes, coolant, air filters, oil filters, or most of the other consumables that the Jetta requires. We charge the Sparrow mostly at night when the utility has excess capacity, so our Sparrow does not pollute, either. Overnight if the batteries are empty.
