Bad driver - in an emergency vehicle!!!

On Tuesday 15 December 2015 in the late evening (after 19:00), a driver in a Ford Ranger, branded with Emer-g-med branding, endangered my life and a few others too. From Klipriviersberg Road, he was driving dangerously close to the back of my vehicle. This continued onto the R59 North. When safe to do so I moved into the left hand lane, but this driver did not pass. A while later, I moved into the fast lane and he moved close to the back of my vehicle again. At this point I could not move over, nor could I go faster due to other traffic on the road. The vehicle in front of me braked, and I did to, the Emer-g-med driver nearly collided with my vehicle! He then wove through traffic, pulled up next to me and started shouting at me. When I pulled out my camera to take a photograph of his vehicle, he then backed off and drove normally.<br> <br> Driving on our roads is dangerous enough, but an emergency response vehicle sees the results of unsafe driving, surely he of all people should drive safely?????
