It's wild how different the refueling process is between our countries. Paying at the pump was trialed here about 10 years ago, but next to nobody used it. We just rock up to the servo, pump our fuel, then walk inside to pay. I can't see it changing anytime soon. Some rural, more crime-ridden areas require pre-pay, as well as a few locations in urban areas between 11pm and 5am, but even then, you still walk inside or up to a window on the actual building to pay.
