A Sydney driver has allegedly made a Nazi salute and assaulted another man before fleeing the scene in a troubling road rage attack in the city's north-west.
The incident occurred yesterday when a 48-year-old man was driving along the road, and a black ute stopped in front of him.
The driver got out of the ute and allegedly used a Nazi salute, assaulted the man and fled the scene.
