Rocky Coaster
I think that putting a few backward-facing seats on a coaster would be really easy to do. With little to no extra cost, this could give riders an extra thrill and a choice of how to experience the coaster. Despite this, I can only think of a few examples of backward coasters, and I can't think of any that feature both directions on one train. From 2013 to 2015, Six Flags reversed the seats on several of their Batman The Ride inverted coasters for a limited time, but each ride returned to its normal operation in less than a year. From 1982 to 2007, Racer at Kings Island had one track with forward-facing trains and one track with backward-facing trains, but that ride now only has seats facing forward.
