You're in a hurry to get to work on time and run outside and your car is covered with snow and ice. It's a pain and let's be honest, once in a while you just scrape a little circle out so you can see and it's 'good enough for now'.

Toss plastic grocery bags or ziplock bags on your side mirrors when you get out of the car and that way when you wake up the next morning, take off those bags, toss them on your floor for next time and just GO. No scraping, no worrying and it's fast.
