The coexist sticker was on the Chinese dudes SUV. That was why poked fun at the brother running over his big brother, in the carjacked car.
Have you seen a picture of the sticker on the SUV, or relying on the media reports. There was a picture posted of the Coexist sticker and it was not on a Mercedes SUV. I Doubt seriously the Chinese dude would have that sticker on a Mercedes.
