Reed made a face at the 'Prius' comment. It wasn't that he didn't appreciate Toyota's efforts to go green or even the celebrity status the car had gained (what with nearly every important person owning one to show how they too were going green), but Reed found the design flawed. And he thought the car was less than graceful looking so there was that too.
Speaking of designs being less than graceful looking, he looked at the model in confusion, "You don't like it? It's simple; clean." Not particularly aerodynamic, he'd admit, but Reed certainly didn't think it was really really really boring as Johnny seemed to.
