Thanks to
@NateD1226 for suggesting to turn a mini-thought in The Miscellaneous Thoughts Thread into an actual thread
There is page on Wikipedia that obviously no one cares about and it shows, called List of Disney attractions that were never built
en.wikipedia.org
The first half of the page is not bad at all, but once you get to the second half of the page it gets bad. Stuff like Jolly Old England (in American Wharf), Incredibles Dark Ride (in place of Superstar Limo), Tarzan Rainforest Rollercoaster, "Mussion" to Mars at Tokyo Disneyland, Superstar Limo in the Chinese Theater at HS! Maybe one or two of these things were actual ideas being tossed around, but none of these have sources! Pages like these are why Wikipedia is viewed as an untrustworthy source of information.
