22: Cut Back On Trash
As is the case with most long-term driving situations, if you spend a lot of time in your car there is a lot of trash built-up. The trash cans that they sell for use inside of a vehicle are usually very small. This doesn’t bode well when you have a lot of people in your car or are too busy to clean it out (via Family Handyman).

Fortunately, there’s a useful piece of Tupperware that you can use. It’s that one that you put cereal in. These make a great trash can because you can put a liner inside and the top makes it easy to pop open and drop trash into it. Your car will become cleaner and you’ll notice that you have a much easier place to put your trash.
