>> You need actual distances to objects, not just fuzzy error-prone inferences.

Humans do pretty good with fuzzy notions of where the animal is. Exact distances aren't needed so much as reasonable estimates. If it is probably in the "need to brake zone" then the car brakes. Plus or minus a few meters isn't a big deal so long as you've got margins to work with. As animals are unpredictable, Volvo certainly has wide margins.

Plus if there is anything the human vision system is optimized for it would be seeing and assessing an unknown large mammal.

History (and personal experience) shows pretty clearly that humans are really bad at predicting the movements of kangaroos, though. (I've never been in a car that hit one, but have had some close calls)

The things seem to be able to effortlessly execute 90 degree turns between hops, at speed.

Safety lesson: if you see kangaroos travelling alongside the road you're driving on, slow way down so you can execute an emergency stop, if needed; they're always only one hop from suddenly being right in front of you.

Safety lesson 2: there is always another kangaroo. If you see a kangaroo bound across the road ahead of you, slow way down; there's likely to be another kangaroo a very short distance behind it. (And safety lesson 2 recurses and also applies to that second kangaroo; there is likely a third kangaroo just far enough behind it that you'll think there's no third kangaroo. And so on.)

Another is - don't let your dogs near a kangaroo around a body of water. The kangaroo hops into the water, the dog follows and the kangaroo holds it under and drowns it.

But apparently humans get confused by kangaroos too, based on the number of collisions.

It's not confusion as other Australians here have said they really do not behave like any other animal and appear out of no where at speed. A actual collision with one normally takes out the car and not just the kangaroo as well.

They're hard to see because of their coat, move quickly and erratically and they're pretty much all muscle.

I'm not surprised they get hit as often as they do particularly at night.
