Before self-serve gas became the norm, drivers pulled up to the pump and an attendant filled a car's fuel tank. Someday soon that may be the case, except the attendant will be a robot. The robot system finds the fuel filling door and gas cap and uses suction to open them. Next, it inserts one of three nozzles into the vehicle's fuel neck through a capless system and fills'er up. After topping off, fueling stops via a vacuum-based shutoff system. Fueling time is reduced by 30% and drivers never have to leave the car. That's good news for those in a hurry or those of us who battle the winter months with below zero wind chills. I only have one question, will the robot clean my windows?
