The issue however, is Merlin controls everything in that region. So compare something like DBGT to literally any other dark ride merlin has ever produced. That is why people think that ride is the greatest thing since sliced bread.
EDIT: I'd also like to add that America is a very lawsuit happy place, so something where you get off the ride and run around before getting back on makes it seem so much cooler. Disney was supposedly going to shoot for something like DBGT, where in the middle of the trackless ride, you get out of the car, run with a stormtrooper through some battle scenes, and then get back in the car a couple hundred yards down. This shows that a level of interactivity can not only increase capacity, but can also increase rider positivity, as they feel like they're truly doing something in the experience, which is what every park tries to do (as seen with a massive increase in shooter dark rides, interactive queues, and stuff like this)
