Winnipeg has a Confusion Corner. I imagine it's not as messy as NYC, but it is confusing for anyone who doesn't get into the correct lane well in advance. There are, I think, 7 streets which come together all at once, with nothing as sensible as a traffic circle to deal with the cars, and the signs for the lanes and directions are not clear - one particular sign looks very much like the new name of The Artist Formerly Known as Prince.
