Electric cars have one advantage: When utilities are out and gas is rationed, those with solar systems can charge and drive.
No they won’t. They’ll need a solar array bigger than anyone has installed right now to adequately charge an EV; and that will be far down the list after keeping the lights on in the house and the building heated adequately.
If the EV owner is the only one moving; they’re not going to get very far anyway. Besides getting hijacked, if they manage to avoid ambush, they won’t be able to venture far from the vast solar array; and there won’t be anywhere to go besides with everything closed.
