Optical Illusion Makes Traffic Disappear [VIDEO]

A short clip of traffic that seemingly shows cars and motorcycles moving along a bridge above murky water. When they make a left turn, rather than driving off into the distance, they completely disappear.

Can't figure out what's going on? Well, it's pretty simple. The video was recorded from a terrace or a balcony and the thing that looks like the side of a bridge is actually just a rooftop railing while the murky water is the roof. The cars aren't vanishing, they're just getting obscured by the building.
