I rarely if ever use the stock mirror anymore. BTW, the small mirror at the bottom of the stock mirror is crap. WHY is it there?
i use the <otherwise> worthless bottom part to look at/near the rear
tires so that when im backing up i can make sure im still on the driveway
(but close the the grass).
oh and initally i used it to confirm that my double walled 5" tip was
still on the tailpipe (since i hadnt tack welded the $$ thing on)
