There were reports quite recently about guys crashing into other cars and pedestrians while drag racing in Durban.
But ja, keep on "redlining" it for now. Perhaps you, and those around you, are fortunate enough not to have your car smash into them, and you will keep promoting illegal street drags.
Until the unthinkable happens....
They were under the infuence and the hype at drag events does get carried away and drivers act stupid.
