From Sonic Retro
Sonic Ride is an unreleased arcade ride made by Sega where the ride-goer would get a feeling of running alongside Sonic during a typical level, in 3D CG. The ride itself was never released, but the video which would play during the ride was released as an extra on Sonic Jam. GamePro accidentally mistook images from the video as the first released images of Knuckles Chaotix in an article of one of its issues. Parts of the video were also used in a music video for They Call Me Sonic.
After a brief sequence drifting through a casino-styled area called Casino Zone, Sonic suddenly appears running towards the camera in a Green Hill Zone style area. The camera switches behind Sonic, who then runs to the right at a fork, and follows still as he dodges a Buzz Bomber and hits a spring, throwing him high into the air, from where the viewer can see a nice overhead shot of the zone. Hitting the ground, the camera runs around a loop, then runs into a rocky area, jumping from wall to wall, dodging startled looking Moto Bugs.
The camera then switches to a telescope view of Sonic running towards Robotnik, and he is standing by a contraption designed to drop a 200 ton weight onto Sonic when a lever is pulled. He moves into position, and as we see Sonic get closer, Robotnik excitedly throws away the telescope and stands by the switch. As he tries to pull it, Sonic zooms past, leaving a trail of dust in his wake and sending the machine and Robotnik spinning. They move back and forth, dizzy, and just as Robotnik regains his balance and pulls a pose - the weight drops, squashing him flat.
