SUPER BOWL 2012

Last week I was trying to figure out how a Zamperla Demolition Derby ride worked. After a lot of research and digging through the interwebs I have finally found some answers.

There's also another variation called the Cuddle Up (or cuddle-up) which I think depends on the number of turntables involved. Anyways, here are a few of the patents with diagrams of the flat rides with intersecting ride paths:
