Tie it to the bike so that it goes parralel to the ground and sticks some 30 cm to the left (if you ride on the right side of the road). Tie a piece of red cloth to the end of the branch. Cars will give you room.
I've been contemplating some sort of similar device utilizing a coat hanger wire, and something to reinforce the rigidity out to 36" beyond my mirror.
I was talking with another rider yesterday and she was working on a similar device with a diamond point on the end.
