Appears due to liability concerns after last year’s Paradise fire.
Rather than improving tech, accepting it was an accident, or some other option…shut down power for 800k people.
As @louisgray observed, similar to TSA security theater at airports.
Bay Area governments have banned scooters & straws, made ride sharing worse at SFO, and blocked new housing. All in the name of the public good.
Now even the 100+ year old innovation called electrical power is too risky.
