Go Karts on their own rail that allow you to sort of steer back and forth and accelerate while being led around a path. I understand why this ride is still here, given it's history, but it is too slow moving and hard to use what limited control you have to be any fun. Your kids probably will enjoy the sensation of driving, though.
Tucked away in a small but comfortable location next to Space Mountain is the Tomorrowland Indy Speedway. Having survived in the Magic Kingdom since the 1970's, Indy Speedway is a simple but enjoyable ride.
Queue- There really isn't much to say about the attraction's queue. You are mainly walking through an outdoor line with nothing to look at but some colorful umbrellas and Speedway facts. The theming is very simple but is not really an eyesore. 7.4/10 stars
Ride- Like the queue the ride is a simple things that many people can enjoy. 8.6/10 stars
Overall: 8.1/10 stars
