What happens when the electricity goes out? And the food in the fridge goes bad and nobody can get to the store because the electric car isn't charged? Have we really thought this through? Redundant energy sources makes sense.

My car rarely goes lower than 70% charged. I charge it to 80% every night (recommended) and use less than 10% every day. On average, my EV is fuller than my diesel was at any random point.

With many cars now you get V2L charging, so you can use the giant battery in your car to power your fridge. You have to keep your car charged, but that is easy to do if you have a charger at home.

  So you're saying that something like Powerwall will be the backup power solution? An additional $15,000?

    No, they're saying the EV can act like a powerwall, a free bonus capability.

    A power wall 3 is 13.5kWh, many evs are 40 to 100kWh

You always have some battery left in the car. There is no need to go to 0% as it can be very inconvenient and it can also damage the battery on some types of chemistry. Most people never reached home with 0%. So if electricity goes out, you most likely have more than enough range to drive to a nearby store or fast charger. If electricity goes out for an extended amount of time in a large radius around you, that sucks and you may have to find alternative solutions such as walking, running, skiing, biking… It’s not scary or considered as big issues in Norway. Many many people enjoy that kind of activities even with electricity. Electricity goes out rarely too. I think I had two short incidents in the last 10 years.

I remember a concern during Y2K prep that an extended power outage would cause problems pumping gas (and Diesel, which would be the real hurdle for rebooting logistics).
