In the Bay Area, it's regularly an occurrence where people in the Santa Cruz Mountains will not have power for 2 days to a week. With little to no notice too.
You come home with a low battery to refill it at home, you might not be able to get very far. Hopefully you just drive with 50+ miles ready all the time.
Unless I someday get to live somewhere with a very substantial solar system, I won't ever be with only an electric car. Grid-delivered electricity isn't reliable enough to bet on.
And consider storms like hurricanes Irma and Maria which left many areas of the Caribbean without power for multiple months.
That said I also remember a hurricane (Harvey?) which shut down refineries, making gasoline scarce. So it's pick your poison.
I lived in SoCal for 24 years and the only major(>3 hours) power outage I remember was https://en.wikipedia.org/wiki/2011_Southwest_blackout and IIRC it lasted less than a day. That said, a major seismic event could occur anywhere in CA and cause outages for much longer than that.
PG&E's safety outages are a fact of life of living in California
Is this due to natural disaster risk or lack of maintenance for infrastructure? I've lived in Austria & Germany for 15 years now and only once experienced a power outage (I think it lasted about 15 minutes).
I don’t think power reliability should be a concern... except for when the big one strikes. But in that case all the freeway overpasses will collapse, so an ICE car won’t help you anyway.
