Moose must be hard to detect too I wonder how they tested for them.

Imagine a 700kg (1,500 pound) moose with velvety brown fur suddenly wanting to cross the road at night in front of your car when you are traveling 120km/h (74mph).

That weight is all up high too on spindly legs. It's like running into a high table with 700kg of weigh on it.

Emus have a similar effect - a good amount of mass sitting up quite high on little thin legs. The things punch straight through the windscreen when you hit them.

Emus have the added bonus too of running directly at you when you sound the horn, instead of away as you'd expect. It's quite uncanny, and problematic at a hundred kilometres an hour.
