Brother, always keep a wide mouth jar or empty peanut butter tub in the car for those type of situations. Saved me more than once being stuck in city traffic. I keep a small pack with some food items and water also you just never know especially in cities. You could get creative with a condom, some hose and an old IV bag but a jar and a towel (just in case of a spill or cover if need be) works best. Haha!
