I don't really care who wins.
But if your car causes a safety car then you get it back on to the train while they clean up your mess, that car should get a drive though penalty after the restart. Of the first three I think they caused 4 safety cars and all stayed on the lead lap!
The drivers who caused safety cars did get drive throughs. Whincup got one for an unsafe re-entry to the track and Ingall got one for stuffing up and putting Holdsworth off. The other crashes at turn two were because the track was breaking up. You can't give the company that did the resurface job a drive through. All other safety cars incidences the driver penalised themselves.
The incident between Murphy and Ambrose was the fault of both drivers. Neither driver wanted to back off so they both crashed and penalised themselves.
