Well, it gets even better ... because Targa says "he's nothing at all to do with us, he is just the local cop who made a prick of himself" But two of the articles say he was a road clearance car, in direct contradiction to that.
He's obviously not associated with Targa, as any car entering the stage has stickers plastered all over it, even the police cars (I speak from experience).
I spectated that corner two years back, and as best I recall it is a junction, where they make a slightly more than 90 degree left turn, to cross a bridge. There's gravel and gunk on the surface, and it is downhill to the 90 left.
There's a couple of meters down to a paddock, then another couple down to the creek.
A bunch of cars crashed there while I was watching.
