Discription of Events: This happened on I-440 Raleigh, in the afternoon 09/19/2018. I watched back of my car before changing a road line on my left. There was a car running super fast and almost hit my car, after I had changed the road line. The driver, however, car-horned me then THROW someting at my car. I was able to see the driver, a black dude. This was a kind of road rage.
