I can see it being more elegant than that. As others have mentioned, it's very similar to kuka-arm coasters like HP Forbidden Journey at UIoA. But instead of the ride vehicle always "floating in air" (being suspended from the kuka arm), Disney's patent might make it possible for the vehicle to be in contact with the surface of the race track.
In the image below, imagine the arm is attached to the back bumper area of the ride vehicle. In this position, it would work a lot like Radiator Springs Racers- the vehiclerides on the "dirt" road, but it's propelled by the arm, which is connected to a track below the surface.

Then, as the vehicle runs alongside a wall/cliff, the under-road coaster track routes to beside the car (Figs 6 in the patent), with the arm protruding from a slot in the wall. In this position, the car is still "on the road," but now it can be lifted/shifted by the arm for a jump or obstacle avoidance (Fig 9).
Because it's attached to the back of the vehicle (Figs 7 & 8 ), it would mostly be out of view for the rider.
I have no idea what I'm talking about. Just having fun imagining applications of the patent for the Piston Peak ride.
