Idling cars drive me crazy. Over the past few years, I have noticed this happening more and more around Bozeman. It’s a year-round phenomenon, which I have spotted everywhere including places one wouldn't expect such as the parking lots at the Community Food Co-op and Crosscut Mountain Sports Center. Additionally, it’s not uncommon to see people sitting in their idling cars tapping on their phones before they drive off after a trip to the store, and you could make a game out of counting how many idling cars you spot on a cool morning in late fall as you commute to work by bike.
