That’s why a video like this one below is so disturbing, and has caused a huge stir on social media. News24 reports:The clip shows a motorist picking up from 179km/h driving towards OR Tambo International Airport when a motorbike, also seemingly speeding, starts approaching the vehicle. It is unclear when the video was taken but the time on the screen displaying the speed shows 16:08. A voice from someone inside the vehicle is heard instructing the driver in Afrikaans to allow the motorbike to ride past and then to catch up. “Laat hom gaan, laat hom gaan, dan gaan haal jy hom” (let him go, let him go, then go after him) the man says to the driver.
