What Are These ‘Wings’ On The Back Of This Car?

My brother-in-law sent me a picture this morning asking me "what are the wings on the back of this car?", and I don't know the answer.

The picture was taken at the corner of Bertrand Drive and Johnston Street and, judging by the angle of the picture, the winged car was taking a left on Johnston to head towards UL.

At first glance, the "wings" look like sensors that might tell the driver if there is someone in their blind spot. But, I am not a sensor expert, so I may be way off. Maybe they are boudin sensors that send a message to the driver's dashboard to alert him or her when nearing a link of boudin, also giving the 8-digit grid coordinates along with the national average price-per-pound information for the day (because boudin matters). Again, I'm not a sensor expert, so I may be way off (wishful thinking, right?).

What do you think they are?
