Although riders can influence the spinning by turning the steering wheel, it doesn't take long to realize that--between the cars' momentum and the many sharp turns in the track--the cabs seem to have a mind of their own. That's actually a plus on this ride, because your struggles to guide the lurching vehicle add to the ride's slapstick atmosphere.
If you want it to spin constantly, it's going to fight you. If you don't want to spin at all, you're still going to pivot a lot. And if you just want to keep facing forward to take pictures...yeah, good luck with that!
Out-of-control craziness is the order of the day at Roger Rabbit's Car Toon Spin, and that seems like the perfect approach for a Toontown adventure.
