In the years that I've riden cars / trucks and likes, there is always something hanging on the rear view mirror. Rosaries, Dice, Pine tree (pabango), compass etc. I personally hang a rosary on the rear view mirror because I believe that it'll save me somehow from danger. I don't idolize the said rosary but to think that it is used in praying, it would help you drive safe and in comfort.

How bout you guys? What do you hang on the rear view mirror?
