...bloody good gear those Subaru wipers

Seriously, I'm not convinced they're up to the job (the Roo-stoppers, not the Subie wipers).
What I
AM convinced of is:
1. Kangaroos are really
really really stupid, they make Pauline Hanson look like Einstein.
2. They have absolutely no comprehension of what a road is, nor what any type of road vehicle is, nor any idea what damage any said road vehicle will do to them.
3. Their actions under stress are entirely random and reasoning does not enter into the equation at all.
4. They have a memory span of about two minutes.
5. They travel in large groups with a collective IQ of about 30, and most of that belongs to the roo in front at the time.
6. Whistling at one and expecting a reasoning "I'd better get the fark outta here" response, when they will quite happily play Russian roulette with a motorbike/car/bus or B-Double, is a tad hopeful and a triumph of marketing.
