Cronic report him I reckon. Reckless drivers need to get off our roads.
I had one gold VY commodore with the chev badging tailgate me on hanson road, when i slowed down he got really pissed off, overtook me in my wife's corolla and slammed on his brakes to a halt. He wanted to punch on, so i kept driving to westfield arndale where it's more populated. He followed me all the way to the shopping centre, and started giving me shit about slowing down... wtf! so i came out told him to f**k off and he wouldn't leave me alone until I started acting like a tough guy. Anyhow, didn't bother reporting him.. but i should've.
