I call out BS one dollar a charge. At 12 cents a kwh in OK its almost $2 to charge 16 kwh of batteries. And I live in a state adjacent to OK withe the same nominal kwh charge. However when you include all the #$&*: fees (like cellphones) the true cost is 18 cents a kwh. At this rate $2 gasoline in in a compact car is the same cost per mile for electric per mile (6 cents).

I suspect he is averaging the free charging at work which cuts the true cost in half.
