A poll: What does 2 blinks of the left signal mean to you?

I assumed it was #1. However, I pay attention to what the vehicle is doing whether or not it has directionals on, etc. Have seen too many incidences of one directional on and the driver goes in the opposite direction. I will sit behind a vehicle for hours if necessary before I will pass if I cannot see clearly. If the vehicle in front of me moves to the right, the driver motions for me to go by and I can get a clean shot I will go. Those that don't like my caution can learn patience.
