My 'most important electronics' might be different than yours, they're my AC, well pump, and refrigerators/freezers. :) But yes, you can still run them for a while...as long as you're willing to make the tradeoff that you can't leave the house without losing power, and using the car as your home energy supply means trading transportation charge for power. That makes me uneasy.
And of course, where I might be able to get in the car or my old beater truck, drive 50 miles, and come back with 50 gallons of gas, generator running for my family all the while, I guess recharging the battery would be...a much more troublesome venture. If gas stations have trouble with capacity during those times, then the length of the charging time is going to have a massive disparate impact on the lines on charging stations. It's going to be nightmarish. And I also have to think about husbanding my car charge so there's enough to leave and get recharged...
I think the "car as backup generator" is a fantastic idea for those unpredictable short blackouts that happen once in a blue moon, just not for hurricanes. I probably would buy an electric car before I bought an automatic whole-home generator.
