18: Store Your Coffee
Many drivers drink coffee, and if you commute there is a good chance that you will have hot coffee in your car at some point in time. If you are going on a family vacation or you commute with a lot of people then you’ll notice that storing your hot coffee is difficult. A new vehicle only has so many cup holders and if you have a full house then you are going to be out of cup holders very quickly on a trip (via Family Handyman).
Nevertheless, there’s a hack that can help alleviate this long-running problem for travelers. Have a pair of old shoes that you don’t wear anymore? Don’t laugh, because you can use these as a cup holder in a pinch. The shoe is generally pretty stable and you can place them throughout the car, you’ll notice that all of a sudden you have a lot more cup holders than you thought you did.
