It is unlikely, IMHO, that a national will be (a) reported for rude gestures, and (b) if reported, will be treated similar to an expat.
That said, I had an "encounter" with a young local, who tried to make a 4th lane in a 3 lane road and then tried to "intimidate" me by pulling alongside me, removing his sunglasses and making a strange face. I burst out laughing and kept laughing! He was embarrassed. (I also happened to have my camera and took a picture of his license plate as he squeezed into the lane beside me). I mentioned it to a local colleague and asked if he thought I might be in trouble if the driver reported the incident to the police. My colleague laughed and said the driver would be too humiliated to actually report me, that the driver would be scolded for being aggressive (and driving in a negligent manner) towards a middle aged woman.
