Add multi-day electrical outages to the list. During the Northeast Blackout in 2003 you simply could not buy gas for several days in many places because gas pumps run on, you guessed it, electricity.

Actually, I think owning an EV would make me less worried about multi-day blackouts. You can charge an EV from a gas or diesel generator or solar (or wind or...), but a gas car can only run on gas.
