A roller coaster includes a cab that is rotatable between position for loading and unloading of passenger(s) and a position for riding the roller coaster. The cab includes a sliding pad mechanism, which is slidable on station entry and/or exit cams to move the cab between the two positions. In the position for loading and unloading the passenger(s), the cab is arranged so that the passenger(s) are non-parallel to a track of the roller coaster, and in the position for riding, the cab is arranged so that the passenger(s) are substantially parallel to the track.
