I see, from Joybell above, That Melbourne (Victoria, Australia) has one carter-corner crossing in the CBD. Sydney (New South Wales, Australia) also has one; where Park St, the main road east-west, crosses George St, the north-south main road of the city. It's a big intersection ... wide roadways plus a bit of a dog-leg as it passes the Town Hall ... so the diagonal crossing does need a good turn of speed!
Frankly, I never heard the crossing method described by any name at all ... maybe we're all too puffed after the catty-scramble!
