Cabnet driver tries to run other car off the road

On Friday night in Observatory myself and others on the street witnessed one of your cabs driving through a red robot at full speed in pursuit of another vehicle and then trying to ram the car off the road. The car he was chasing reversed against the flow of traffic back up to the traffic lights and turned down a different road to escape. Your driver then also reversed down the road and followed them. This behaviour was extremely dangerous and people could have died. I can't believe that you would hire drivers who would behave so aggressively, especially with your signage all over their vehicle. I will never use your service and I know everyone who was on the street and witnessed this incident won't either. I hope you investigate this and fire the driver involved. I think his car registration started with 407.
