@paco TIL: there's a tiny arrow next to the car's fuel gauge to indicate on which side of the car the fuel port is. It is named after its inventor, James Moylan who worked at Ford.

Until today I've only been aware of the existence of such an indicator through a false sort-of rumor that said that the fuel pump icon indicated this through the side on which the fuel nozzle was drawn.

Good to know the name of the well-intentioned person who made this happen.
