I really wish they were building this at WDW. It looks very cool, the whole area actually, and I don't see a trip to California anywhere in our foreseeable future.
What did we expect? It is nearly full-sized cars on a track racing through scenery - of course it is going to resemble TT - it is nearly the same exact concept with a different setting and story line.
It is just crazy that POTC, IASM, and all other boat rides all have nearly identical boats...
