I agree there should have been a mini-utopia in the land with miniatures of the Cars characters to drive. But not at the expense of Radiator Springs Racers.
-and I'm not sure why people keep thinking that I'm advocating for the removal of RSR. My belief has always been a land themed to Route 66 and car culture but not exclusively locked into the franchise, Cars. Because then, you can build an amazing ride like RSR and do things like move the Autopia over from Disneyland (to free up expansion space there), and think about more creative attractions or include other IPs to widen your audience net.
Anaheim isn't like Disney World. They can't just keep building outwardly as much as they feel like it. They need to be smart about what goes where long term because they'll inevitably want to expand again at some point or shake things up.
The issue I'm trying to illustrate is this: imagine if over in Disneyland, instead of Main Street USA, Tomorrowland, Adventureland, New Orleans Square, Critter Country, Galaxy's Edge, Fantasyland, Frontierland and Toon Town (9 "generic" themed lands) we had 9 lands, each dedicated to a single film or franchise. Instead, imagine if we had UP-land, Snow White-land, Roger Rabbit-land, Winnie the Pooh-land, Toy Story-land, Iron-Man-Land, Zorro-land, Princess and the Frog-land and A New Hope-land. That's literally what "Carsland" has done to the space over in DCA.
Hyper specific, single franchise lands, all 9 of them. Would they be fun? Absolutely! But you're not allowed to think of or include attractions from
other franchises or even other ideas, in general. You're now effectively also land-locked and unable to build anything truly new. Because they wouldn't have thought long term. That's why it's better to have a land like "Tomorrowland" which finds home for Buzz, Star Wars, Space Mountain, Nemo, etc. instead of just "Finding Nemo-land".
That's the only point I'm trying to make here regarding my opinions on the matter. Should RSR exisit? Absolutely! But it should exist within a land that is able to have
other attractions from other ideas. Not just from Cars.
