Race three start at Winton

[Nowornever]

Why don't more drivers get a running start like Craig Ferguson did on the winner of this race.

Just hang back 10 lengths and then as they are lining up start sprinting and you get a huge advantage at full speed while the rest are just getting started. Not the first time I have seen this and there is obviously no penalty for it with the weak stipes, so looks like a loophole at the start for drivers who do this.
