Disneyland does not have the blessing of size like the Magic Kingdom has, but it has attractions literally built on top of one another to increase the number of attractions. The Subs are underneath Autopia practically entire attraction except for loading and unloading. Why doesn't the Tomorrowland Speedway follow that example? Now, I am not saying that the subs should be put in, but would you agree that it is a good idea for Disney to put a ride under the speedway? In my opinion, the ride should be a "future underground city tour" and it should be a dark ride. The loading/unloading station could be on the path east of the speedway that nobody uses. What do you think of the idea and what do you think could be put under the speedway?
