[QUOTE=Laker14;2258726]The gate arms do more than just create an illusion (although I doubt the developer and its sales team do little to dissuade potential buyers from believing in the illusion), that they create a visible and predictable break in traffic, in between each automobile, to facilitate golf cart crossings at those intersections.
True for entrance gates but not exit gates. Exit gates have a time delay and typically do not come down after every car when there is a line of cars passing through.
