I have a yellow ResQMe hanging from my rear view mirror. I'm thinking that if I am needing it, I will be in panic mode and will not think to look in an ashtray etc. I'm hoping it will catch my eye and I will grab it. It is also accessible to the front passenger. If the rear passenger can get out of their seatbelt it can be used by them to break the window.

I'm open to other ideas!
