It's about
damn time they started using trackless tech in America amirite?
Hunny Hunt was the first iteration, but interestingly, the load/unload was on sort of guide rail chain.
After, some flat rides like Aquatopia, and much later on the second Luigi flat ride came to be.
Ratatouille and Mystic Manor shared their tech as Disney's dark ride version #2 except for a small motion base integrated on Rat's puck.
Rise of the Resistance and seemingly Mickey, use the same or similar system, but I have no idea. They just look the same in that they don't have pucks and they are also both capable of varying levels of acceleration.
Ironically, Mystic Manor and Ratatouille use trackless with little importance, but it doesn't detract all that much. Tokyo's Beauty uses an animatronic non-passenger vehicle like Pooh instead of Rise or Mickey where the vehicle
itself is also part of the story.
With exception to Rise, they all suffer a 'flatness,' but it doesn't hurt the parks since there is so much variation of attractions and tech. There are
a few intimate moments in every trackless ride, but overall you feel there are gaps, so I definitely see that point. I think ride variation is what's more important, however. Maybe this decade will see the criminally underused EMV at more parks after trackless was king of the 10's, or even Shanghai Pirates' tech.
Trackless is at its peak when vehicles participate in the story.
