I love the idea of bringing the flying saucers back this idea was also in a concept painting for paradise pier a the orginal DCA preview.
However turning cool flying saucers into car tires in a junkyard seems to be "playing" down what would be a much cooler concept like i dunno maybe Flying saucers!!
You know they wont ever build these tho since heavyset people bottom them out and they wont move, they have a narrow range of weight where they work well too low and you cant manuever to high and it wont move, do you really think disney is going to have a scale outside the queue to weigh people to see if they can ride??! lol
