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.
