I imagine most everybody is able to scramble around in the dark using flashlights which gathering up family photo albums, important documents, pets, and children. And to drive out of the area down unilluminated streets and through intersections where there are no traffic signals.
But only the jerkwads in California government would actually oblige their citizenry to do so.
Part of the plan. people flee California, and spread the sickness. Colorado, Texas, Idaho, Montana.... all going blue. Which will lead to further breakdowns and spread the contagion.
Heck.
