Same. It is the same ride vehicle. But the story and experience is way better.
Truthfully, the first time I rode Indy in the 90's I did not "get it" and said to myself "get me out of here". The ride was so jerky and annoying. But I tried it again. After riding it a few times I started to like it. And if it were not for my beloved POTC, Indy would be my favorite ride at all of DLR.
