Yes. It's foolish to compare the cost of consumable gas vs consumable electricity.
Much better is consumable gasoline versus battery depreciation. Electricity costs nearly disappear.
This was an old adage among the homebrew EV crowd: buying a battery pack is pre-paying for your fuel for the next N years.
The Powerwall[1] is about 35 cents per KWh, assuming it can handle 1000 full cycles. ($3500 for 10KWh capacity.) A decent EV can get 5 miles out of that, so the battery depreciation is 7 cents a mile. That's a multiple of the electricity cost, which is about 2 cents a mile if you don't try for any time-of-day billing.
[1] This is just my best comparison of the actual cost of a Tesla battery.
30mpg at $2.25/gal is 7.5c per mile. Versus 9c for an EV (7c battery, 2c elec), this is a $1500 over 100k miles. If we consider the other maintenance costs, I think they are nearly equivalent.
This thread is rapidly entering territory where only a comprehensive comparison of TCO will suffice (not that those won't be biased either way), but the price of the battery is only one part of the price of the car. 70k$ amortized over 300k miles is still 23¢/mile.
I understand Tesla's luxury-first strategy and hope the future part will pan out, but at the present time it is very weird to be making a cost based argument.
