Reckless driving - Gautrain bus driver

I would like to report a bus for dangerous and reckless driving. Basically almost driven off the road by a gautrain bus. If I had not reacted to being cut off by the bus trying to force his way between cars to avoid traffic, he would have hit me and caused a major accident. Disgusted at the complete indifference of the bus driver while putting both passangers and motorists lives at risk with 0 regard for the consequences of trying to squeeze a Bus between cars on the road. Furious at this reckless driving I hope action is taken against this drive before he causes a major accident on the road
