As you drive, note how many homes have three or four vehicles parked in their driveway And most have some sort of “toy” out of view....four wheelers, boats, motorcycles, etc.
Those highway vehicles may be greater in number than the number who drive, so they don’t operate every day. But batteries must be kept charged when not in use or the computers will drain them.
So the questions raised by the OP are not only legit, they are going to be a real deal breaker unless the government intends to restrict the number of vehicles per household.
The electrical requirements will otherwise require a total rebuild from the power plant to your front door...including the high voltage transmission lines and their towers.
The Left doesn’t envision EVs replacing ICE vehicles.
Their goal is to destroy society and western civilization. On the rubble they think they can build “The New Man.”
You’ll have nothing, eat bugs, and like it . . . or else.
