I don't want to sound like i'm defending lesser-quality, but for one thing, the ride could easily be renamed. Second, the Race portion is a gimmick to add a sense of thrill like with Test Track. The dark ride part of RSR is the best part of the ride, hands down (and i've actually been on it). The ride could easily exist, dark ride only and be a great ride.
And I know everyone criticizes TDO for being cheap, and most of the time they are, but the rock work for Carsland was INSANELY expensive. If they went ahead with that again, I highly doubt we'd get any of the other rumored additions simply because of the inflated costs.
Truth be told, right now only a few select people know what's in store for this. But from everything i've been hearing, i'd expect some variation of what I posted in my prior post.
