To non Australians, they seem like cute puppies that bounce, but in reality they're a huge pest and terrifying when they appear out of nowhere on the highway.
When driving from Kalgoorlie (a remote mining town in the middle of the desert) to Perth (the capital city in that state) one must complete the 6 hour drive across featureless plains during the daylight hours only.
Trying to drive at night will result in kangaroos approaching your headlights, then your passenger vehicle is hitting a 200lb (90kg) mammal whilst driving at 70mph (110kmh) which is never going to end well.
I once (stupidly) drove through (unfamiliar) country Victoria to catch a morning flight at Tullamarine. I was about 3 hours drive away so I started at 3 am.
By 4am I was driving 60-70km/hr along a single carriageway when suddenly my car was flanked on either side by a mob of a dozen roos matching my speed pushing me to the center of the road. If my window was open I could have easily stroked the head of the nearest one.
I knew they couldn't keep up for long so I just tried to match their speed before they eventually started to slow and peel off, at which point I took off in front.
Was probably a couple of minutes but felt like half an hour.
Had a car been coming in the other direction we'd probably all be dead.
