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

I never ever circumvent the standard printed rules of the road. Never wave someone ahead at a for way stop, never cede my right of way to facilitate someone elses driving. Never. Not because I am a prick or rude, but because rules and etiquette are in place to help us all.
Helpful Hank waving someone ahead or yielding his turn only serve to confuse folks. Driving is hazardous enough with out people just tossing wild cards into the deck!
