Why is the hand signal for turning left a parallel left arm pointing left, but to turn right it is still the left arm, bent at the elbow hand upward at a 45 degree angle to the ground?If we signal left with the left arm, couldn't we just signal right with the right arm?
(Actually, I just figured out the answer typing this. Does anyone else know the answer?)

well, superman, am not able to see thru metal yet...you?
Hummm...Could it be because it's easier for the driver behind to see the hand signal when done from the left side?
Okay, okay. You are right. Signalling with the right arm when inside a car makes logical sense. But when I raised the question, it was after seeing someone on a motorcycle (like in the picture) and it looked more like waving than signalling.
BTW-it is accepted protocol to signal with the right hand when on a bike, even though I, like hundreds of others were taught all left-hand signalling.
I believe, on a bicycle or motorcycle, it is permissible to signal a right turn with the right hand.
Additionally, the throttle is always located on the right handle bar; therefore, if one was to signal with the right hand the potential of loosing speed and not being able to accellerate through the turn increases the probability of an accident occuring...
Not being a cool biker boy, I didn't think about the last bit on a motorized bicycle.
