I know exactly how power hungry it is. Yet we have been powering them at home for decades.

But 8 hours a day or more of charging? Where are you getting your math from? Or what are you smoking so I can have some? According to my charger stats, I charge roughly twice a week for maybe 4 hours at most each session. That's less than 8 hours a week.

8 hours of charging nets me about 200 miles of range. Who regularly drives 200 miles a day? I am sure someone does, but they aren't the average car owner by any stretch.
