A closer look

Gas gauges in almost every modern car have a tiny, easily ignored triangular arrow right next to the fuel pump icon that points directly to the side of the car where the gas tank cap is located. This incredibly useful feature was secretly added by designers decades ago, yet millions of drivers still pull up to the pump on the wrong side and have to perform a walk of shame dragging the hose across their trunk. It is a brilliant piece of idiot-proof engineering that is entirely wasted on a population that refuses to look at their dashboard unless the check engine light is flashing a fiery red. Automakers gave us a literal cheat code for refueling, but we prefer to rely on pure guesswork and stubbornness, ensuring gas stations remain a prime location for awkward public failures!
