Probably a regional / marketing thing. Certainly it was "Spotswood" in Australia and New Zealand at the time of release. Spotswood is the name the Melbourne suburb where the film is set. I don't think I've ever been to Spotswood, but I have been to neighbouring Williamstown and I recall there was a commercial slot car racing layout in a retail location above a shop. This was 15 years ago so probably long gone. I remember wondering whether there was a connection to the movie, some kind of local slot car culture of some kind.
