So if you drove 1,250 miles per month (15K/yr) and charged at home every night, you'd have used 463 kWh at $0.08 per, for a total monthly electric rate of $37.00..... yep, thirty seven bucks a month to drive your Tesla if you paid for every bit of electricity.
That's SoCal pricing. Savings would be even greater in some parts of the country (in Minneapolis the off-peak EV rate is $0.035/kWh)

I understand that EVs may be worthwhile in the future but, unfortunately for now, you guys are not using real world scenarios to come up with your new found savings.
Super-charges WON'T be prolific in the foreseeable future unless you are looking at a VERY SMALL and densely populated area like LA. This is a case of city people telling the rest of the country to use mass-transit. Show me the subway station in TN.
If you "really rack up the miles" you are going to be getting a lot of tow bills when you run out of juice before lunch. The thing that would help pay for the higher cost of the vehicle is not attainable due to limits of range.
So-Cal prices for elec is higher but, where I live, the cost of power is not the issue. Its getting the charge WHEN and WHERE I need it. Lastly, if the EVs become plentiful then the off-peak rate will jump up to compensate for the lower advantage to the utility. Eventually there will be very little difference in Off-Peak rates. Also, higher demand will stress the Grid that is already on the ragged edge of being overloaded. This means higher elec costs ALL day to cover the cost of upgrading the grid to cover greater demand. I saw this happen with LILCO many years ago. We paid more for building the nuclear plants so we could get cheaper electricity but the rates never went down.
As stated before, there will be additional taxes levied to cover the lost income for gas tax. In the long run, you will pay as much or more for an EV yet still have lower range.
