I have spoken to too many people who have no clue what the left arm up signal means. While on a bicycle, I have actually had a driver tell me they thought I was going to turn left. Pointing the direction I intend on turning, however, seems to be understood by even the dumbest drivers.
I agree that drivers ed should be more rigorous and perhaps a short refresher course online before renewing might be in order.
