It's a nasty gasoline powered stinking glorified go-cart, but you know what? Kids absolutely LOVE those kinds of rides. It doesn't matter that it goes 2 mph and can't really be steered, KIDS think they're really driving! When I say kids, I mean little bitty guys that barely meet the height requirement. It's not going anywhere soon, unless Disney just absolutely has to have the space, because it is a huge tract of land.
Love the idea of the cars interacting with other cars, and even other racing props (a la CARS), but not necessarily a fan of electric unless they really try to make some realistic noises with the cars. Racing cars that sound like a gerbil running in a wheel is not appealing to anyone, especially the target group for that type of ride.
