well the real cause of the accident is still not known but there are some rumours which friends of mine told me which might've caused the accident. First is that, some people say that the driver Majid Naeem had removed the side mirrors from his car in order to reduce the weight before racing. And during the race, at about 160+kmh he turned around just to look at the gap he was giving the corvette he was racing and thats when he lost his attention and the 900hp beast got out of control. the other rumour is that, Majid removed the diffuser and sideskirts from his car before starting the race and due to made aerodynamics, the car crashed. and lastly, some people say that the cold weather in islamabad (the temperature was in the bracket of 0-10celsius)wasnt favourable for such high performance cars to race due to less traction. I dont know if all this is true or not, but both the Driver and the Organizer of this event both are arrested.
