How often do you see kangaroos in the wild?
I'm in Canberra, and we have an annual cull of Eastern Grey Kangaroos in the local nature reserves, because there are so many of them they actually put other wildlife at risk by over grazing and destroying habitat of some endangered species.
I live in a suburb and have had kangaroos in my yard on occasion. We only need to drive 2 minutes to regularly see large mobs of them in a nearby reserve. It's probably as exciting for us to see a kangaroo as it is for you to see a squirrel.
Canberra has one of the highest rates of insurance claims for vehicle damage caused by kangaroos, because it was designed for all suburbs to be within quick and easy access to nature reserves, so there are kangaroos all through the city.
While Kangaroos do quite a lot of panel damage to vehicles, hitting a wombat also causes a lot of damage to a car, because it takes out sumps, diffs etc. You might as well drive into a boulder. They're not huge animals, but they are solid.
