I was thinking the same thing, being capable of storing the juice is one thing, getting the juice in there is another. You can’t put a substation up at every charging spot. The grid is already failing on hot summer days, now think of a place like Southern California plugging in eight million cars a day. It would be amazing for off grid power though. They’re even pushing electric semi-trucks, one Pilot would take down the power grid in four states lol. And what’s the temperature operating range? Not to mention they are passing laws that allow the state to suck the power out of your car and put it back into the grid.
