I agree with you here. But that electricity had to be made somewhere, I don't think they're producing any 100% efficient power stations yet. So multiply your motor efficiency rating by the efficiency of the powerplant to get the actualy energy input to make the EV move.

Again, the electricity had to be generated somewhere. Unless it was via renewables, then a fossil-fueled plant with all its inefficiencies produced it. Coal, CNG, or something else was used to make it. The electricity didn't just appear out of thin air. That's why well-to-wheels is the only fair comparison, IMO.
