a total mileage/charge requirement if we all went electric?

You can work out average energy per day, but not how bursty the charging is,
which is what sets the network current. For example, a rapid charger will
consume roughly the same energy as a slow charger, but needs a much bigger
grid connection. The charging speed is set by the usage pattern of the car,
not by the energy requirement (for example, owner doesn't have a charging
point at home so rapid charges while doing the supermarket shop).
