it feels like it should be easier to plug in a few times a week rather than drive to a gas station, stop the car, exit the car, insert card, enter pin/zip code, open gas cap, remove nozzle, insert nozzle, pump, wait for pumping, remove and return nozzle, close gas cap, take receipt (optional at some stations), return to car, start car, and leave. yes, you have to stop and start the car when plugging in at home, but you already have to do those things, whereas driving to a gas station is additional stopping and starting.
