From a cyclist's perspective, in my area, this would not be an issue. The auto would have passed me - with or without me motioning him around. He also would have gunned the engine and most probably either flipped me off or he would have swerved toward me. I need to move to a more biker-friendly area.
From a driver's perspective, I think that you did the right thing. Well, it's what I would have done @ least!
