Had a nasty case of a Golf GTI dicing me this morning - from behind.
I filtered to the front, then pulled away normally when Green and moved to the right (I was going to turn right soon). Mr Golf GTI decided Challenge Accepted and chased me from behind, almost rear-ended me. He put me in an extremely dangerous situation and forced me to go a lot quicker than comfortable.
So, if you live in Centurion, watch out for a white Golf GTI with some (pink?) writing on the hatch. He's going to kill someone or dice you, specifically if you ride something slower like a scooter or a two-wheeled Jeep like my 800GS.
