In other news though, I'm loving the dual exhaust and the wheels. I can't wait to see a black one with a chromed (or at least silver) grille, and its side profile is absolutely amazing.
As for the trailer hitch thing, I'd imagine it has something to do with the testing. Maybe they had to haul something or attach some sensor or do something to throw its center of mass off. I doubt a trailer hitch would come standard.
