Utilizing the same ride tech in a different attraction with a different theme barely registers with ordinary guests. Radiator Springs Racers is Test Track with about a few billion more bells and whistles. A high tech dark ride won't appear as "Meh, it's just a Spider-Man clone" to the general population. They see it as a cool thing to do on their vacation.
With that argument, it invalidates those wanting Radiator Springs Racers to come to WDW since, after all, it is just Test Track with a different theme.
