All the reviews I've been reading of Radiator Springs Racers have been comparing it to Test Track.
However I haven't been to Epcot for decades. I am quite familiar with the Journey to the Centre of the Earth ride at Tokyo Disney Sea though.
Its a richly detailed dark ride using the Test Track technology with a short thrill section at the end (mostly a drop). So seems like it would be a very similar experience to RSR.
Could anyone who has experienced both rides post a comparison?
