Go take that thing off your mirror NOW! Various vehicle codes address the issue of fuzzy dice, graduation tassles and air fresheners ( I like ocean breeze whale's breath to mask the stale beer stench of my recycling efforts <img src="/images/graemlins/grin.gif" alt="" />) as visual obstacles. They are also deadly missiles in an impact if broken free. I know of a death from an empty cigar box flying off the rear window deck and breaking the driver's neck. I would ducttape the tool lower in a mutually accessable local such as the center console or radio. Cut some small 'startertears' on tape's edge to facilitate tearing.
