I have no idea what you are talking about. There aren't that many hand gestures that require that the fingers be highly visible. These gestures are not usually conveying positive sentiments. The driver of a single track vehicle should NEVER use hand gestures to convey negative or angry information around cagers. The cager may go to jail (or not) for killing a cyclist that has flipped them off, but it won't bring the cyclist (or motorcyclist) back to life.
