I didn't want to see a car clouting a geese either, but I'm a bit skeptical whenever some non-crash related SC occurs these days, particulary after the Darwin Holden flag on the track requiring a SC a few years back.
They'd certainly cause a heap of damage to a race car at speed, but turn 4 is probably the lowest speed section of the track where it was best for them to have been.
Did anyone know where they did end up getting herded off to ?
