You compare a 3 seater with no cargo to the gas mileage a full size pick up gets that can haul 1000 pounds of cargo and 3 people. With a 3 year limited warranty my guess is they aren't standing behind your guess that zero maintainance will be needed. What they dont have parts that wear, need greased etc. I notice you also add maintainance for the gas vehicle but mention no figure for insurance on a $38,000 piece of plastic. I would love to see how that vehicle handles in a crash test first.
Now as to the gas vs electric cost if everyone switches electricity demand goes through the roof and cost expands to cover the new needed electrical demands. You cant build power plants for free. Following the law of supply and demand the kw goes up. Plus your car sits out all day unplugged and all the little devices sap the power. Are you going to pull over and charge your car for 10 hours before getting home? uld the government take more tax dollars than they already do to support these vehicles and build charging stations for them?
In addition, I do not know about you but I often drive my car for other things besides work. Got a date? Sorry honey cant take you out tonite I have to charge up my car.
