Mind Blown

Have you ever borrowed your spouses/parents/friends car or been in a rental and gone to fill up the tank only to discover you have no idea what side it's on? Ford. All Fords are on the drivers side, right? Or is that Toyotas? Ultimately you pull in, park and have to immediately get back in and pull around to the other side because you chose wrong. Turns out you don't have to guess. Most cars will tell you. Have you ever noticed the little arrow on the gas gauge? Cause I never had...

PS- Pay no mind to the fact that my gas gage tells me I have absolutely no gas....I like to live dangerously.
