What drives me nuts is when the light turns green, a left-turner will either just sit where they were for the red, waiting for a space to open, and turn, or, they inch up, literally a few inches, then space opens, make the turn, only that car is able to turn before red again. Rules of the Road here in IL are to pull out, into the intersection, perpendicular to the lane you are turning into, which means essentially the middle of the intersection, not the line one was at for the red. If people followed that, generally a minimum of two, maybe three cars could left turn, even if no spaces opened up before turning red again. I so often wonder how people became licensed in the first place.
