Autopia is a track ride in Tomorrowland at Disneyland. While it's not the best, it is also recommended.
With is redesigned track, cars, and queuing area (that means the place where you wait to go onto the ride :D) autopia seems to be at its best. The ride has gone through several renovations and now is a great ride, though the long lines are a bit of a drag, especially later at night, the new track will take you through jungles, futuristic car parks, and of course, the exit line. The ride is about 3-7 minutes depending on how fast you trek (or ride!) and is still great for kids. While adults may not like it as much, try riding at night, its more fun that you think!! Also check the fast-pass station, it makes the ride more fun because there is never a wait for a fast-pass.
