Wild Mouse roller coasters did not exist when Matterhorn was built. They came after Matterhorn proved steel-tracked coasters were viable. Space Mountain's track system (except for the computerized block braking system), ride vehicle, loading zones, and lift hill layout were lifted almost directly from Matterhorn. The rest was designed specifically for the 1975 version of Space Mountain, with no reference to Franz Mack's 1960s carnival coasters. Except for the initial, single 180-degree turnback after the lift hill at the beginning of the ride, there is no similarity to a Wild Mouse track layout at all. It is very easy to learn the difference between the feel of a Wild Mouse in the dark and any version of Space Mountain. The Dark Knight coasters at Six Flags parks are Wild Mouse coasters in the dark, and they're awful.
