Automating the buggy whip-robot tank fueling devices

Via Bruce Sterling: Robots Take Over Car Fueling In The Netherlands At "TankPitstop". View the cool video, and then ask, so much human energy for such a trivial and short term problem. I suppose as proof of concept of robots in the field interact with civilians, it has its uses, but (a) since when were people too lazy or unskilled to pump gas (i.e. the driver is still sitting in the car), and (b) once cars are plug-in electrics, will we need a robot to plug the car into the socket, or maybe we get a home robot to plug the car into the socket, and then a robot to plug that robot in, and then a robot to plug *that* robot in, and so on.
