re: This is really random but this is the off topic board so I suppose it belongs here

The point is that you don't have to guess. You can find the number of cars driven per day. Look up the KVA of a charger. 60 amps sounds high. Look at the charge curve for car batteries to calculate the charge times. Some guessing there is necessary. Then compare your sum total to the grid capacity in CA.

And then, take your work to the politics board where more will join you in griping about governments.
