Drivers of said blockades are oblivious to honking/tailgating/light flashing. They have a sixth sense that keeps them at the exact speed of the car(s) next to them regardless of whether the other car attempts to speed up or slow down.
More often than not, annoyed drivers behind you will ride your ass thinking it will magically lift the blockade making for a most unpleasant experience.
