I was riding the Harley before I was riding the bicycle and we always used the side specific hand to signal anything: lane changes, turns, debris, railroad tracks, whatever.....so when I started riding bicycles again I just transferred that to the bike. I use the side specific arm to signal what I'm doing. With the drivers here in NM - I'd be afraid if I used the bent-left-arm to signal a right hand turn some idiot SUV driver would take my arm off with their mirror!
