wow 5.7cm that is huge compared to my Take-A-Look mirror.
Well, no matter the size or where it is mounted, my comment was really about "possibilities of life threatening incidents" in regard to lightning--what I hoped to illustrate is that getting sqwershed by Mr and Mrs Retiree in a fricken Love Boat sized RV, or Billy Bob in his pickup pulling a trailer who doesnt give a rats ass, these sort of risks are magnitudes of times more of a danger to us than getting hit by lightening or getting a bonk or 20 on the head by hail.....
