I agree. The “bent left elbow upwards” move makes sense as an option if you are in a car and don’t have a 10’ right arm to reach out of the passenger window to point right, but that limitation isn’t the same on a bike. I’m never braking the same time I’m signaling on my bike anyway- I signal way before.

Though at least my state handbook’s section on cycling says that pointing right is also an option one could use (after explaining the bent left elbow signal).
