I use a neck lanyard with a snap-together keychain. This keeps the camera at about waist level & handy to drop in a tankbag pocket. For off the bike shots I just disconnect the keychain. The whole rig fits handily into my camera case.
Great tip on taping the mode knob on the camera to keep it from moving. I had one that would always turn when I put it into the tank bag. Lost a bunch of pictures that way as it would turn to high ISO which washed them all out. Like a dummy, I never thought of taping the knob, I just bought a new camera.....
