As a mince, in bolognese (we don't eat roadkill here. Besides they are relatively easy to farm, unlike 'roo.) Those larger creatures do significant damage when hit at highway speeds, so bullbars, nudgebars and smartbars tend to continuously be fitted even though there are actually legal restrictions on them. One guy seems to have had one on his rig earlier this week, as he seems to have deliberately run over several kangaroos in my area. One had to be put down by police, and it was obviously deliberate as he had to leave the road at several points to run them down.
