I was led to believe this ride was going to be snake-themed. Shows how much I know, heh.
I don't know, if they wanted to actually tease it as a Batman-themed ride, they could've had Wayne Enterprises be the one who bought out Motorama, or when they closed Rockville High it could've been due to...oh, mold caused by some poisonous ivy plant, or since Rockville was undergoing an "urban renewal," some of those signs could've been vandalized with "THE JOKER WAS HERE, LOLOLOLOL" but I guess that would've been too obvious.
