Reckless driving

My family, 1 boy of 7 and 1 baby of 5 months traveling from Johannesburg to Cape Town. Was extremely pleasant until one of these busses almost drove into us! We were behind another truck and the bus was behind us flashing his lights. He was probably 2 meters away from our car. Could have easily been in an accident if the truck in front of us had to brake! They are so reckless I do not recommend anyone traveling with this company they are bad and because of people like this accidents happen on the long road.
