I super glued a helmet cam attachment which i also modified to the back of my rear view mirror, small discreet and easily detached, if i need to film left or right i just turn the rear view mirror
I don't see why @RockThinking couldn't make these available for sale as I think there are a number of people asking about them. One of mine cracked while trying to get the tripod base out, so I could use a couple more.
