Tomorrowland Speedway, formerly known as Grand Prix Raceway, is a ride through twists and turns in go cart-like race cars. I believe you have to be 40 inches to ride by yourself but a child can ride with a parent. It's not fast but fast enough as the kids steer the cars on a single track so they get the feel of a steering wheel without going off the course.
We like this one a lot and the kids never mind waiting in line. The cars move 4 at a time so the line moves quickly. They strap you in and you go through a course similar to Le Mans or some other type of European raceway. It takes 2-3 minutes but the feel of a car is fun for everyone. The cars ran faster at one time but they've slowed them down over the years. Still worth not passing up.
I don't think there is a Fast Pass option for this ride so check it out when the lines are lighter.
