Your comment makes no sense. Do you think that a Prius would be disabled by a failed electric power grid? Really? Can you explain how that would happen?
Perhaps not the Prius exactly, but the name stands in as shorthand for other similar devices be they EV, electric go cart, horseless carriage... whatever you want to call them.
Electricity dependent motor vehicle, does that make it easier to comprehend? When grid down, car no go.
That’s the basis of my earlier statement. I didn’t realize this thread would serve as catnip for the pedantic.
