This statement ignores the dynamic pricing of markets. The gas station is full today, but the marginal electrical care affects the supply/demand curve for gas today and in the future. If the current point of the supply/demand curve drops too low, supply will start to shut off. Hence, electric cars are only "pointless" in the past before they were invented.
