Yesterland has a neat story on a retired Disneyland ride Midget Autopia:
It’s the only Autopia where every car has two steering wheels. But Mom or Dad can’t sit next to you. This Autopia is for kids only. And while the other Autopias look like freeways, this one is more of a country road. [...]
The Midget Autopia was a favorite of Very Young guests. But it fell victim to another favorite of the Very Young—It’s a Small World. The Midget Autopia closed in April 1966 to make way for a wide new path up to It’s a Small World (June 1966). The once-popular Midget Autopia was paved over.
But that wasn’t the end of the Midget Autopia. Walt Disney donated the ride to his boyhood hometown of Marceline, Missouri, where it was installed in a park named in his honor. For several years, the former Disneyland attraction operated as a ride for the children of Marceline. Unfortunately, the cars were too difficult and expensive to maintain.
