well, first of all - the driver who mowed down the bystanders were NOT racing. So you make your own judgement that "illegal racing" is the killer or simply a reckless driver himself.....
if he was blinded by all that wheelspin smoke - he should have STOPPED until visibility cleared. And what on earth was he doing being so close until the smoke was blinding him?
Maybe he was the organiser? Well, drive safely all of you.
Hey, imagine if the Gurney driver snow sprayers blinded the car driver by coating his windscreen and he panicked and mowed down spectators.....scary and yes, can possibily happen.
