The British, Australian, South African and Canadian Highway Codes are, allowing for temporal drift of local conditions over the decades, probably still largely interchangeable. But these local variables can catch you out. In Melbourne, for instance, I was tootling along a main drag in a midengined car, secure in the belief that I had the right of way over everyone. A fat lady in an old Holden flattened my expensive motor around my ankles and was most abusive: it turned out that drivers from the right (in Oz one drives on the the left of the road) had right of way, no matter how minor their entry road. A chum got knocked off his bike in exactly the same situation, a couple of blocks further along that road.
