I tend to believe they'd want a consistent ride for everyone...and then part of me thinks this is kind of a fun ideaOkay...hear me out on this highly unlikely and possibly impossible theory about the leg ticklers.
What if instead of the whole ride or a few carts having leg ticklers...it was just a couple of seats.
Others brought up that this ride was billed as a psychological thrill ride. Whats more psychological than having someone doubt their own memories or senses? Imagine getting off the ride with family and friends and bringing up the leg ticklers only for your party to look at you funny?
IDK just a random thought.
