In spite of living & riding in a state which does not recognize the extended right arm for a right turn, I signal a right turn with my right arm. Like Diggy 88, I also point with two fingers.
As an older roadie, I find performing the bent left arm for a right turn difficult from an aggressive road position. Sit right there as you read this, and make the left-arm, right turn signal. Now bend your forearm 45 degrees back from the angle of your upper body. Now many of you ladies out there may have no problem with this, but I think few of the gents can do it.
In my cycling classes, I teach & demonstrate the law and then show them right arm for right turn. I even done in from of Joe Law with no problems. Of course, I doubt they know the law.
Trust me, I'm a LCI.
