Stupid or no

depending on your state DMV laws, having things hang from your rear view mirror can be illegal.

i like to keep mine clear of obstructions. especially things that reflect and refract light. my cousin had a small disco ball hanging from hers at one point and she caused an accident cuz someone else was blinded from the light reflecting off of it and it blinded the other driver momentarily enough to have them hit another car. so smart.
