I use a plastic grocery store bag, I loop the handles on the corner of the open glove compartment, then close it tight. I empty it once a week on trash pickup day, or sooner if it's full. I couldn't imagine not having one
tissues, granola bar wrappers, water bottles etc...even if I brought it in with me when I got home, it would make me nuts just having all that stuffed in cup holders or on the floor in the meantime, seems easier to just toss them in the bag as I need to instead of gathering it all up later
