Nearly got pushed off the road

Firstly while standing and waiting at a robot at the cnr of Bond Street and main avenue this driver has his bakkie half way over the lane for oncoming traffic trying to overtake me when I turn right at the robot. Then at the intersection of Oxford and Eton road this guy swerves in front of me causing me to swerve in to oncoming traffic. He looks at me in the rear view mirror and shows me the middle finger. He then proceeds to simply turn right with no indication or steady breaking. I have photographs of his licence plate when he was forced to stop at the stop sign. <br> This all happened just after 4 today.
