Well actually you/anyone could speculate and guess...and probably would be wrong. And it is not unrealistic to have a car sit for many days until loading. It's a gobal shipping thing they have going...lots of cars and countries. It can sit for some time.
My best counsel: sit back...wait till it is loaded, [which you have to do anyway] get confirm from dealer and then track and enjoy to cruise. Anything else, while fun to think about is really only a guess. Good luck and happy sightings along the route.
