The last time I rode Autopia was in 2008 because my dad wanted to do it. I remember sitting there thinking to myself, I should have just waited and driven the real car when we left the parking garage.
For me personally the Autopia is a waste of space and a waste of time. It smells horrible, it's noisy, the wait time isn't worth it, and it's another thing that is only fun for little kids and teenagers who don't have their license yet. If it's ever ripped out and replaced with something else I don't think I'll be upset at all. The last three times I've visited I've walked right past it without even thinking about riding.
