Don't you hate it when you're getting gas and the gas cap keeps getting in the way of things? Apparently there's a hack that solves that problem in two seconds, and it looks like we aren't the only ones who just found out about it. To keep the gas cap out of the way, just unscrew the cap, pull it out from inside the car, and place it on the hook that's on the side of the gas tank's door. Yup, who knew?
