World of Motion was mostly about the history of transportation as I recall and seemed like it was time for a refresh. Test Track was intended to give a flavor of the types of things that take place during the development of a new vehicle. Haven't ridden this newest iteration, but the videos seem more like it is about the future of transportation. Not sure if people will think that is good/bad, but clearly a different focus. Glad they have eliminated designing your own car since it seemed pointless and just another place to queue before getting on the ride. As I recall, no matter how long it took you to design your car, you still waited in the same line as everyone else.
