I don't like it. I've never liked it. Even as a little kid.
The seats are uncomfortable, the place reaks of deisel (no, I can't spell), the steering wheel is iffy, the cars are loud, and the lines were always long. It lacks story and is no longer themacticly relevant to Tomorrowland. I say kick it out.
Don't ask me what it should be replaced with- I have absolutely no idea. I definitely don't want it to just sit there like a certain track that will remian unnamed... Oh, why am I even speculating, Disney'll never take it out.
