I realise it's a joke and the details are irrelevant, but an EV is probably going to take weeks to drain its battery just sitting on in the garage. Days if it's running the A/C.
Moving the vehicle costs so much energy that it's a bit shocking how long an EV battery lasts if you use it for things other than driving.
Even still, my EV could run the electric dryer for 12h straight on the highest settings. Washer is a rounding error in that estimate. It takes a lot to use up am EV battery.
I'm not sure about other EVs, but the Ford Lightning specifically has a whole home inverter/backup interface that allows you to safely plug your EV in using the same Ford charger you use to charge and power your home in an outage, automatically switching between the grid and the Lightning
I only know this because I had to install one for a customer, so again no idea if that's as streamlined for other EVs
There are a number of EVs and PHEVs capable of "vehicle-to-home" power transfer as long as they have a bi-directional charger. The Lightning is just particularly well suited for it due to its massive battery.
PHEVs as well, since they have a gas tank which enables using the vehicle as a generator, so that in an extended outage you have a means of refilling your source of power.
