I’m not sure where in California you’ve lived but I had exactly one place where there was no power available. I’m quite aware that many people do, but it’s still the case that if all of the people who could charge at home did so you’d effectively remove millions of people from the public charger equation and making the problem that much easier.
While I'm sure the charge-at-home number isn't insignificant... I wonder what it really is.
In other words, the percentage of Californian cars that have their own garages/carports. (As opposed to street parking or a spot with no power.)

I personally had the reverse recently: Places without power for 5 days, and long lines of stricken EVs at rare working charging stations.
Perhaps that's an argument for ensuring any home emergency generator one gets can charge an EV, not just keep the contents of a refrigerator safe.
