For starters, Aussies sit on the wrong side of the car, a strange remnant from their days under British rule. Next, they have summer in winter and winter in summer, but you can eventually get used to all of those minor details. It’s harder to get used to the wildlife you can encounter on an Australian racetrack, since you don’t find kangaroos hopping around Road Atlanta or Laguna Seca.
I’ve hit a rabbit at speed on a racetrack, and it was no big deal (speaking form my perspective, not the rabbit’s). A couple of thumps, some fur in the radiator and that’s that; you can’t say the same about a kangaroo, which seems like it would equate to hitting a tall, muscular deer. In fact, kangaroos are just one of the many species of critters that can kill you in Australia, but at least they’re not poisonous (like just about every other Aussie insect or animal).
Maybe they’re on to something here; radio controlled, robotic kangaroos, unleashed at random intervals, would make NASCAR a whole lot more entertaining. It sure would add a new dimension to the sport.
