Cali is now advising people not to travel more than 120 miles from their homes. This is conveniently about the maximum range of an electric vehicle without recharging, so 120 out, 120 back, then overnight to recharge. It's not a bug, it's a feature.
They are also actively discouraging anyone from visiting the state during the plague. Just think; if they were to build a tall fence along their border, they could keep the residents in and the "foreigners" out. Knowing how seriously they take this sort of thinking, I'm thinking that no fence would be required along the southern border as Mexicans are not considered foreigners. Likewise no fence along the Nevada border as this would unreasonably curtail the gambling industry, and none on the Northern border as Oregon is close enough to Cali politically as not to matter. This leaves only the Arizona border where dissident elements from Cali cross to try to buy ammunition and smuggle it back to Cali.
