It is an emergency. I'll compromise in an emergency. My fridge can sit unpowered for a couple hours while I'm driving, and that is all I need to drive anyway.

If there is a major outage most bosses understand that you won't be working normally because you need to deal with the emergency.

The amount of money you spent on a cybertruck could’ve instead been spent on a generator, gasoline for the generator, and a car to go buy gasoline for the generator. Or, battery packs & solar panels, and a generator, and gasoline for the generator, and a car to go buy gasoline for the generator. That car could even be an EV, just a much more efficient one.
