Believe it or not, the parked cars are just reflections as seen on the mirror-tinted window of the San Miguel Building located in the Ortigas Business Center of Pasig City. The building was designed like a pyramid where its windows are slanted outward in a fashion that the cars parked at the side of the building are reflected on them.
If you are new in this area, you will swear that the cars seem to look like they are parked inside the building at a certain angle. I was lucky enough to be stopped in an intersection fronting the said building at the right angle which made the illusion that the cars are inside the building.
