The point has become obscured by some (disingenuous) interjections. Of course most rides feature vehicles that drive themselves... but usually, the vehicles aren't the entire point. An overwhelming majority of rides at WDW are a variation on a dark ride, which emphasizes storytelling and narrative through complicated, multi-media scene building. A few rides take a different approach - AK's Safari, for instance, relies on live animals for interest. Everything we've seen of Cars indicates it is going to be an outdoor trip through more Disney rockwork. The PR material so far has focused on the ride vehicles themselves, attempting to make the "off-roading" vehicles the focus of interest. I and others are arguing that being driven around a bumpy track isn't a substitute for more conventional dark-ride-esque storytelling. Indy or Dinosaur wouldn't be interesting if they were outside through rockwork, however cunningly devised.
