EV's can only improve in efficiency, including in the manufacturing and power sources. The manufacturing of ICE cars and trucks is not exactly a Greenpeace wet dream. You should follow the path of filling the oil pan, coolants, transmission fluids and gas tank...how those are made and transported. Each tank of gas is inefficiently filled by means of tankers driving around our highways and oceans as opposed to stationary wires for EVs. In addition local solar in parking lots and at home can easily supplement charging in the greenest way possible. Try that with ICE.
