I don't know what to make of this track other than it was just a test. Instead of a branch, I just tried having two completely separate roads side by side, but it looks like Golden Fox seems to be the only one driving on the other road. I can never get paths to work correctly once the map does a world wrap. My position goes completely nuts.
