It looks like they're all pointing straight back, aligned with the car's direction of travel. But for those to generate vortices, they need to present surface area to the flow i.e. be placed at an angle to the flow. So, depending on what the flow field looks like back there, they may or may not be vortex generators.

But, I have several questions:
1) Does generating a vortex or several vortices there mean they'll migrate upward, against gravity?
2) What effect or interaction will that vortex/those vortices have on the large vortices formed naturally and shed by the car's C-pillar?
3) How many times can one say "vortices" before it starts to sound weird?
