They also appear to budget $0 for a home charging station, which means either you're doing all your charging at Tesla chargers, are lucky enough to have a charger at work that is regularly available, or charging at home via a very slow 1-2kW outlet.

120V charging is around 4MPH in most electric vehicles.
