Any ideas?

Are they the sewn-on bug deflectors?
If so, while they would cause a local flow separation, they would be embedded within a favorable pressure gradient, the flow would reattach, and you'd just be dragging two little separation bubbles around wherever you went.
The cost of feeding the turbulence would be weighed against the cost of replacing the windshield, should a small pebble tossed up from a vehicle ahead of you not be deflected.
