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.
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.
