Electric cars are almost 4X as efficient as a gas car, so 1MW of electricy and 4MW of gasoline are roughly equivalent in miles added per minute.

OTOH the only batteries that can absorb 1MW of electricity are those in some Class 8 trucks, and Class 8 diesel trucks are usually filled with pumps a lot faster than a standard gas station pump.

It's a useful comparison for how long it takes to refuel a vehicle, but "moving a liquid storing chemical potential energy through a tube" and "move electricity through a wire [and re-store it as electro-chemical potential energy]" are two such radically different activities that it glosses over a lot to equate the two.
