Here's an idea:
Don't scrap the Autopia, just re-landscape the area to look like the Arctic National Wildlife Refuge. GW Bush could then narrate the ride as kiddies wiz through the arctic tundra in search of the Earth's last remaining crude oil reserves. Watch in awe as the permafrost melts and the caribou die off... all so we can have one more lap around the track! New name for the attraction: "Countdown to Extinction (ours)".
Sorry for this intrusion of the real world into a Dis forum, but this is something that I feel strongly about. Not only is the Autopia dated (ie not futeristic) it is down right irresponsible to show kids that the continued burning of fossil fuels is still the transportation solution of tomorrow. I know, I know... Its just a ride and the kids love it. Fine. Keep it, but dump Chevron and update the attraction with clean energy technologies. It can (and should) be done.
Or, they could re-landscape the area to look like Iraq...............
