I would guess it is a cheap way to let air escape or flow through the rear bumper.

We have this issue with the Panther platform vehicles ( Ford Crown Victoria, Grand Marquis, Town Car). We call it "balooning". The bumpers on these cars are quite large and they do collect air at highway speeds. Many people have done bumper tucks, or, like I did, install a plastic cover that practically eliminates most of the balooning.
Most cop cars/ taxis don't have this done. If you're behind one on the highway, check to see if it's lifted up.
